  • The number one reason is for your safety and protection. The pressure relief valve allows steam and hot water to escape safely from your water heater. Water heaters are designed to operate within a safe margin of temperatures and pressures. Should one of the internal safety features fail the pressure relief valve operates to keep your home and family safe. - Source: Internet
  • I had this with a previous house. I’ve also had a house where in spite of having a hot water shut-off, the valve was leaky and was mainly only useful for damage limitation. The solution is pretty simple - turn off the cold water inlet and drain down the entire system, hot and cold. - Source: Internet
  • In any case, checking the temperature of the water in your system is easy. A meat thermometer from the kitchen is the right tool. Open the hot water faucet in your kitchen sink and let it run for a few minutes to ensure that you are getting water directly from the water heater. Check the temperature of the water with the meat thermometer. - Source: Internet
  • Unlike ball and gate valves, globe valves allow you to control how much water is flowing in addition to whether the water flows at all. They include an internal plunger that moves up and down to control water flow depending on how much you turn the valve’s handle. Since they allow for variable control, these valves commonly control pipes leading to sprinkler systems, but you might find them attached to other pipes as well. Residential globe valves can cost anywhere from $5 to $70, but they typically fall between $10 and $25. - Source: Internet

  • Fixture valves feature small twist knobs or handles. They let you turn off the water from an individual fixture, like a toilet or refrigerator, without turning off the water in other areas of the house, making them helpful for repairing individual fixtures in your home. Most houses feature a variety of fixture valves, typically ranging in cost from $50 to $150. - Source: Internet
  • If the pressure relief valve on your water heater has been replaced in the past, you may have a problem. There are different relief valves available for different applications. Domestic water heater relief valves are much different from relief valves meant for boilers or other applications. These valves may look the same, but their pressure ratings and temperature ratings are much different. - Source: Internet
  • In addition, most houses built today have small, localized shutoff valves called fixture supply stops (Photo 7) installed on the supply lines leading to toilets, faucets, dishwashers, washing machines, water softeners and water heaters. These supply stops usually have a small round or oval handle that you turn clockwise two to four full turns to shut off the flow of water. Many older homes have them only at toilets, if at all. This can lead to great family discord, since working on a single drippy faucet can require shutting off water to the entire house at the main valve, leaving everyone shower-less, flush-less and waterless. With supply valves, you can turn off the water to a single fixture while fixing or replacing that faucet. - Source: Internet
  • Over-pressurizing your home’s water system is a serious situation. Typical home plumbing systems can suffer damage from high pressure that can lead to catastrophic losses. A burst pipe or a failed valve can do immense damage to your home if undiscovered for even a short time. - Source: Internet
  • Like gate valves, ball valves are an all-or-nothing valve, controlling only whether the water is on or off and not the flow. They feature a relatively thick middle body, which holds the ball used to control the water. Typically used as the main water shut-off valve in a home, you can usually turn them off quickly as they only require a quarter-turn of a lever handle. Ball valves typically cost around $10 to $20. - Source: Internet
  • The check valve line is where the RV and the city water first meet. This needs some anti-freeze too. Your water pump should be off before adding the anti-freeze. - Source: Internet
  • Make sure you fill and ensure there’s no air in the tank before you turn it on, or you’ll fry the upper heating element…you need to purge the air by opening hot water valves upstairs until it runs free without any air…then, you can turn the WH back on. A WH element that gets turned on without water surrounding it will melt. - Source: Internet

If you don’t have a basement, the main water valve might be concealed behind an access panel. - Source: Internet
  • The winterization process can be a baffling practice for a new RV owner. It varies slightly depending on the model of the vehicle, but certain aspects are standard in all RVs. One such practice is the water heater bypass. - Source: Internet
  • Yes, there might be exceptions. From my 365+ days of plumbing experience as a fully qualified and master homeowner, I would guess that on a residential 2 heater parallel installation, installing a hot and cold on each heater might be essential. When 1 heater takes a dump, that heater can be isolated, and the other heater will work without the leaker leaking. - Source: Internet
  • If you are satisfied that there are no leaks, it is time to make hot water again. Turn on the gas valve and relight the pilot light if necessary. Some water heaters have pilotless ignition systems. Make sure the burners light properly and that all the covers are installed correctly. - Source: Internet
  • Shutting off the water supply in your home is usually necessary when you are making plumbing repairs to any of the fixtures or pipes in your home’s plumbing system. There are at least three different places you can shut off the water, and your choice of locations will depend on where the leak or the ​plumbing repair needs to occur. Generally, no tools are required to shut off the water. - Source: Internet
  • When you repair or replace a gas appliance, use these shutoff valves to stop the flow of gas. (Most pros replace the flexible connector when they replace the appliance.) If you discover you have a faulty supply valve, or your system doesn’t have one, turn off the gas using the house side main shutoff valve. - Source: Internet
  • Ensure that the valves on the cold and hot water line are turned perpendicular to the line. Turn the bypass valve in such a way that it is parallel to the line. The anti-freeze will now pass straight through the line bypassing the tanks. - Source: Internet
  • Needle valves were once commonly used to control water supply appliances, like your refrigerator, but many building codes no longer permit their use because they’re not very dependable. If you currently have a needle valve, we recommend replacing it with a more reliable fixture valve. Needle valves typically cost $5 to $20. - Source: Internet
  • Finding water under or around your water heater is never a good sign. The immediate reaction is usually a bit of panic. Is your water heater about to flood your home?

  • The RV water heater has a water line at the bottom where the cold water goes in. On top of that line, there is a hot water line that feeds your pipes. If there is a middle pipe that connects these two lines, congratulations, you have just located the RV’s bypass valve. - Source: Internet
  • The main reason for blocking the stop mechanism within the valve is the sediment buildup. As the water gets warmer and eventually hot, mineral deposits will start extracting at the bottom of the tank. If there is no regular maintenance, sediment buildup can develop heavily, clogging up the drain valve and affecting the performance and efficiency significantly. - Source: Internet
  • With the discharge pipe removed, use your pipe wrench or adjustable wrench to unscrew the pressure relief valve from the water tank. Getting the old valve out may be the hardest part of this project. Removing the old valve may take considerable effort at the first few turns. - Source: Internet
  • Houses with natural gas have a main shutoff valve (Fig. A) located just before the gas meter. This valve, often called the street-side valve, is normally a rectangular nub (Photo 1). When the long side of the nub or handle is parallel to the incoming gas line, it’s open and the gas is flowing. When it’s turned a quarter turn, perpendicular to the incoming pipe, it’s closed. - Source: Internet
  • You have a closed water system, and the water heater is causing the pressure to rise in the system. The pressure relief valve is opening as it should and releasing the excess pressure. You should consult with a licensed plumber to correct this problem. - Source: Internet
  • The valve is designed to be installed at a certain height from the bottom of the tank, so there will always be some water left even if you try to drain the unit thoroughly. Water left at the bottom of the tank will contain most of the harmful and corrosive particles, which can again clog the drain valve. This is why the recommendation is to flush the whole system and remove those deposits. - Source: Internet
  • Hot water from the faucet above 120 degrees is a danger to your family. Water above 120 degrees can burn or scald tender skin. If the water temperature approaches 200 degrees, your water heater may be malfunctioning and needs the attention of a licensed plumber. - Source: Internet
  • Connect the garden hose to the drain at the bottom of the water heater. Run the garden hose outside and then turn on the valve on the water heater drain. Open a tap on a nearby faucet to allow air to enter the system so the tank will drain. - Source: Internet
  • In some cases, the pressure relief valve on your water heater may simply fail. There are several reasons that pressure relief valves fail and begin to leak. Usually, this kind of leak problem is minor, perhaps only a few drops every few minutes. However, even a minor leak should not be dismissed. - Source: Internet
  • You can, of course, call a plumber to make the repair, but most homeowners can easily replace a leaking pressure relief valve in a few simple steps. However, you may need to consider other possibilities if the pressure relief is not faulty but is doing its intended job. Understanding why your water heater has a pressure relief valve and how it works is the key to making good decisions in this case. - Source: Internet
  • Leaks of this nature are usually small and don’t pose much of a problem themselves. The larger problem is a pressure relief valve that may not function properly if it is needed. The valve may fail completely in some rare cases and unleash a flood of water into your home. - Source: Internet
  • A failed thermostat could create a serious explosion hazard unless a pressure relief valve is installed on the water heater. Water, when turned to steam, expands by a factor of 1,200. A water heater without a pressure relief valve is a bomb waiting to explode. Water around your water heater or water dripping from the pressure relief valve is a sign of trouble. - Source: Internet
  • Copper supply lines allow for the use of the same shut off valves as PEX with the addition of solder/sweat-on fittings. Soldering copper is a great method of installation but requires extra plumbing tools and supplies. You can check out our tutorial on solder copper here. - Source: Internet
  • The location of the main water valve in your home is one of the biggest factors in determining cost. An easy-to-access basement valve will cost much less to replace than an outdoor valve buried underground or locked in a vault. National average costs for valves in different locations are listed below. - Source: Internet
  • If there is a missing drain valve, it may be difficult to get the sediment deposits out of the bottom of the tank. If the valve is damaged, it may not be able to operate. If it is leaking, then there is a problem that has to be fixed. - Source: Internet
  • Place your bucket under the pressure relief valve discharge pipe and open the valve. A bit of water should flow out into the bucket. As the water heater drains, the water level will fall below the pressure relief valve opening. The water flow from the discharge will quit. - Source: Internet
  • Pressure relief valves have metal labels around the top of the valve body that show the pressure and temperature ratings. Your water heater should include information about the correct ratings for the pressure relief valve. Make sure that the two match. - Source: Internet
  • The type of water shut off valve you need will depend on many factors. All shut-off valves are designed to stop the flow of water but not all valves are created equal. The shut of valve that best suits your needs will be based on the size of the waterline, the type of appliance it serves, and how the valve is operated. - Source: Internet
  • Outside your home is another shut off at the water meter or curb of your property. Some main water valves require specialized tools to turn this valve OFF and ON. This shut off is best left for professionals to operate and repair. - Source: Internet

These valves are conveniently located close by faucets and appliances to easily facility repair or replacement of these plumbing fixtures. - Source: Internet
  • Shut off valves with a wheel or other multi-turn valves operate by spinning the handle. Turning the handle clockwise will tighten the valve stem inside and force a gate CLOSED or press a rubber gasket against a seat to restrict the flow of water. Alternatively, counter-clockwise will OPEN the valve and allow water to pass through the valve. - Source: Internet
  • Turn both valves so that they lie parallel to the line. This will allow the water to bypass the heater. One-valve system. Simply turn the valve perpendicular to the line on a one-valve system to bypass the hot water tank. - Source: Internet
  • Supply water stop valves are designed to control the flow of water to individual household plumbing fixtures. These valves are located nearby the fixture they serve as the water line enters the room through the floor or wall. You will find supply shut off valves in the cabinet below a sink or tucked away behind a toilet. - Source: Internet
  • Some things in life are worth learning before it’s too late—like the locations of your water and gas shutoff valves. Now granted, these shutoff valves are often hidden in some dark, creepy corner of the house. But if a water pipe springs a leak, knowing where the shutoff valve is could save you thousands in water damage repairs. What’s more, you can’t make those major plumbing repairs or improvements unless you first turn off the water. The same goes for turning off the gas—though with some strict safety precautions, which we’ll talk about later. - Source: Internet

Think of this like the difference between a shut off valve for your toilet that is normally open and your outside hose bib that is normally closed. - Source: Internet
  • Your water heater is leaking? Make sure that it doesn’t come from the valve before replacing it. If your pressure relief valve is leaking, then this maybe because it isn’t seated properly in the tank’s threaded opening. This is quite a common issue if you’ve recently replaced your old valve with a new one. To fix this issue with this cause, you have to take several steps. - Source: Internet
  • If the buildup is severe, try to loosen debris by using the stiff wire or screwdriver. Insert the tool through the drain valve, move it back and forth and in a circular motion. Even if you have loose some, the debris can block the valve again, so repeat the process. - Source: Internet
  • Ball valves or quarter-turn valves operate via a handle on the valve stem that pivots a steel ball with a hole inside to control the flow of water. If the handle is in-line with the valve body, the valve is OPEN and water flows through the hole in the steel ball. Conversely, when the handle is turned perpendicular to the valve the steel ball twists and STOPS the flow of water. - Source: Internet
  • Replace the discharge pipe on the pressure relief valve. In some cases, this is easily accomplished by simply threading the discharge pipe onto the valve. However, if the discharge pipe is PVC or some other material, you may need to replace the entire discharge pipe assembly. - Source: Internet
  • Several problems could cause your pressure relief valve to leak. Understanding the causes of pressure relief valve leaks is important to diagnose the problem. In most cases, the solution to the problem is easy. To solve the pressure relief valve problem, replacing the faulty pressure relief valve is usually the answer. - Source: Internet
  • Carefully screw the new pressure relief valve into the water tank. Make sure you don’t accidentally cross-thread the pressure relief valve. Hand tighten the valve as far as possible, then use your wrench to make the last few turns. Be sure that the opening in the pressure relief valve points down. - Source: Internet
  • Also note: When you shut off main or individual gas valves, you’ll be extinguishing the pilot lights to certain appliances. Many newer appliances have “pilot light–less” electronic ignition systems, but if you have older appliances, you’ll need to relight the pilot lights. Most appliances have clear relighting directions on a label near the pilot light or in the instruction manual. - Source: Internet
  • In many municipalities, you will need to obtain a permit before replacing your main shut-off valve. Expect to pay $50 to $500 for the needed permits. Your plumber should be familiar with the local permitting process. They can provide a cost estimate for the permit itself and any upgrades required as part of that process. - Source: Internet
  • Important! Now that you know where your gas valves are, also know this: it’s not always safe for you to turn these valves off in an emergency. When gas reaches a certain concentration in a room or house, the slightest spark can set off a tremendous explosion. A light switch or telephone—even static electricity from your clothes—can produce such a spark. - Source: Internet
  • Water main shut-off valves are most commonly brass, which is relatively durable and inexpensive. However, other metal materials are available for a higher price. Bronze tends to be more durable than brass when exposed to high levels of chlorine, and stainless steel can last longer under pressure and high temperatures. - Source: Internet
  • In cold climates (Fig. D), the meter and main shutoff valves are located inside, usually in a basement or other warm area to prevent freezing. In milder climates (Fig. C), the meter and its two shutoff valves may be attached to an exterior wall or nestled in an underground box with a removable lid. - Source: Internet
  • Tip Some homes are equipped with branch valves that can be used to shut off the water supply to selected branch lines in the home. These valves will be located along the main branch pipes and are located in accessible utility areas. For example, water pipes feeding outdoor hose faucets are very often controlled by in-line valves that control only the pipes running to the outdoor faucets. - Source: Internet

  • If the water pressure on the supply side of the water heater is too high, the pressure relief valve may open slightly and allow water to escape. This is an unusual situation and not often found. You can test the water pressure in your water supply system yourself. Pressure test gauges with the correct fittings are available at most home improvement stores. - Source: Internet
  • Most people don’t know that the pressure relief valve on their water heater will also open if the temperature inside the water tank becomes too high. It is an unusual situation for a relief valve to open because of high water temperatures. Most relief valves are set to open when the water temperature approaches 210 degrees Fahrenheit. - Source: Internet
  • When the threads on the water tanks are clean, you are ready to install your new pressure relief valve. Wrap Teflon plumbers tape around the threads on the new pressure relief valve. The Teflon tape should be applied in a clockwise direction. Some people apply a thin coat of plumbers pipe dope to the threads as well. - Source: Internet
  • If your leak is somewhere in the main branch line, or if there is no fixture shut-off valve near the fixture you need to repair or replace, find the main shut-off valve for the home. This is usually found in a utility space near where the main water line enters the house, or on an outside wall near the water meter. This valve will always be located on the same side of the house as the water meter and it is usually a rather large valve. - Source: Internet
  • First, shut off your water heater. Wait for it to cool completely. Then, remove the valve and rethread it into the water tank opening. - Source: Internet
  • Surprisingly, many pressure relief valves begin to leak because the valves have never operated. This problem may arise after the pressure relief valve is operated, or it may just happen due to corrosion or sediment build-up. In any case, the pressure relief valve should be replaced. - Source: Internet
  • Pressure relief valves can begin to leak for a variety of reasons. Fortunately, in most cases, replacing the pressure relief valve solves the problem quickly and inexpensively. Most pressure relief valves for water heaters can be purchased for around $15. Removing the old valve and installing the new valve is a relatively simple process. - Source: Internet
  • If your home is newer and you find a flexible copper pipe running from the meter into your utility room, you probably have a higher pressure gas system. In this case, your inside main shutoff valve (Photo 3) is probably near your furnace or water heater, just before it enters a flying saucer–shaped doodad called a pressure regulator. There’s also a chance your home—especially if it’s older—doesn’t have a house-side main shutoff valve. - Source: Internet
  • A water heater has two shut-off valves. A cold water inlet valve (often identified by a blue handle) feeds cold water from the main supply into the water heater. This is the valve to shut off if you need to repair or replace the water heater. - Source: Internet

  • There are two water pipes connected to the water heater. One supplies cold water to the water heater. The other is the hot water outflow pipe that serves the hot water connections in your home. The cold water supply pipe should have a valve that will shut off the water supply to the water heater. Close this valve fully. - Source: Internet
  • Gate valves feature an internal gate that raises and lowers to control water flow. It’s considered an “all-or-nothing” valve because it can only turn the water all the way on or all the way off and cannot manage how hard water flows. These valves are usually controlled with a twist-type knob or handle. Gate valves are more commonly used in industrial applications rather than residential homes, but in some cases, they control a house’s main water pipe. Residential gate valves typically cost around $10 to $50. - Source: Internet

The reasons for replacing the valve might be leaking, clogged, or a broken valve. - Source: Internet
  • If you’ve been noticing any issues with your water heater pressure relief valve, then you need to know where it is on your water heater. Usually, you can find it on the top or side of this appliance. It’s a valve that’s connected to a plastic or metal discharge tube that points up. - Source: Internet
  • If your valve is sticky, then it becomes stuck in a closed (downward) or open (extended position). If it’s closed, then the valve won’t be able to relieve the heat or pressure that builds up in the closed water heater system. There could be a rupture as a result. - Source: Internet
  • Drain valves are found on water heaters and boilers for cleaning and servicing purposes. You can also find drain valves on lawn and sprinkler services so that these water lines can be blown out and winterized. Although drain valves spend most of their working lives closed, they should be exercised regularly to ensure they function properly. - Source: Internet
  • They prefer you turn your water off or on using the main valve on the house side of the meter. This valve will normally be a gate-type valve, with a round knurled handle, requiring several full clockwise rotations to turn off. In newer homes, it could be a ball valve. - Source: Internet
  • The most popular material for water shut of valves is brass. Brass is the material of choice due to its durability and reliability in residential plumbing systems. You can find brass shut off valves throughout your entire home. - Source: Internet
  • Remove the drain valve (especially if it is plastic) using the instructions from above, and replace it with the 3/4" ball valve. Use two 3/4" dielectric nipples to prevent rust. The valve is bigger and stronger, and it will help in the future, preventing sediments from clogging again. - Source: Internet
  • However, the water flow should soon come to a stop. If water continues to flow from the hot water tap after a few minutes, the cold water shut-off valve is not operating properly. You may need a plumber to repair or change the valve. - Source: Internet
  • A bypass prevents anti-freeze from going into the heater. If for some reason anti-freeze does enter the heater, you will need to flush it out completely before you can store more water for showering. Most RVs have this bypass installed. Some RVs have one, two, or three bypass valves. - Source: Internet
  • If you’re working near the main or individual gas valve and clearly know the source of the gas leak and that gas hasn’t been leaking for long, shut off the valve and get out. But if you’re uncertain of the source or how long the gas has been leaking, clear yourself and your family out and call the gas company or fire department from a neighbor’s house (not your own—remember, phones can generate sparks!). Always err on the side of caution. - Source: Internet
  • Check the information for your water heater and make sure you know the temperature and pressure ratings for the relief valve. Most home improvement centers sell water heater pressure relief valves and a modest cost. Usually, the cost is around $15. While you are at the home improvement center, pick up a roll of Teflon plumbers tape and some plumbers pipe dope as well. - Source: Internet
  • Finally, you may also be able to shut off the water at the water meter itself. Water meter boxes sometimes have two shutoff valves, one on the customer side and one on the city side of the meter. This should be a last resort, because in many communities there are ordinances that frown on homeowners touching any part of the plumbing system positioned on the street side of the water meter. The plumbing lines beyond the meter technically belong to the city, so you should not touch this valve unless there is no other option—such as if the main shut-off valve on the house side is non-existent or doesn’t work. - Source: Internet
  • This is for safety reasons. Everything has been done according to standards that have been mandated by plumbing codes. So if you’re having any issues with the valve, you’ll have to call a professional to have it fixed. - Source: Internet
  • Finally, many ice makers and furnace humidifiers are fed by small flexible copper tubes that are connected to larger copper pipes via a very small T-handled device called a saddle valve (Photo 8). These valves essentially bite into the larger pipe to feed the smaller one. Leaky saddle valves are a major cause of residential water damage and are no longer code-compliant in many areas. If you have saddle valves, replace them with standard supply stops. Since these things can leak like crazy and cause tremendous damage, I’m replacing it with a standard supply stop as soon as I’m done with this story. - Source: Internet
  • The average main water valve replacement cost is $600, but that average rises to $875 if a trench is required to reach the valve. The cost continues to rise the deeper you have to dig, as trenching and dirt work often cost hundreds of dollars per excavation foot. If the replacement is being done during the winter, frozen ground and bad weather make access even more difficult. - Source: Internet
  • It’s a good idea to get ready for gas emergencies before they happen, because sometimes projects involving gas lines don’t go as planned. When a gas project goes bad, that’s not the time to be searching for the right tool to shut the gas off at the meter. A good strategy is to buy an emergency gas meter wrench shutoff tool and secure it to the meter as shown in Photo 4. Pick one up at a home center for about $12. - Source: Internet
  • You should never ignore water leaking from the pressure relief valve. Two possibilities exist if water is coming from the pressure relief valve. Either the valve is faulty and needs to be replaced, or the valve is operating correctly. In the latter instance, immediate attention to the situation is required for the safety of your home and family. - Source: Internet
  • It’s important to know where your main shut off valve is in case you need to turn off your water to make water line repairs or your neighbourhood is having water supply issues. Also, some insurance plans will have stipulations that require you to turn the water off to your home if you leave on vacation for more than 48 hours. It’s a good idea to check the fine print of your home insurance policy before you head off on holidays! - Source: Internet
  • Sometimes we see shut-off valves at both the hot and cold pipes near the water heater. There is nothing wrong with it, but the second shut-off at the hot water side is not necessary—except as part of a flush kit for a tankless (on-demand) water heat. What we don’t want to see is no shut-off valve at all, like at the water heater shown below. It gets written up as a defect in the home inspection report. - Source: Internet
  • There is no need to drain the water heater tank any further. Shut off the drain valve and carefully disconnect the garden hose. Drain the garden hose by walking it to the other end. - Source: Internet
  • If your water heater is electric, find the breakers on the circuit breaker panel that protect the electrical circuit. Most water heaters require 220-volt electrical service and will have circuit breakers. Make sure both are in the off position. - Source: Internet
  • To fix a drippy supply valve, try gently tightening the packing nut (Photo 7) with a wrench, or opening and shutting the valve several times until the drip stops. If a supply valve simply won’t stop leaking, your only option is to replace it—which will require shutting off the main valve. In cold climates, most people remember to close the supply shutoffs for their outdoor spigots to prevent freezing, but many then forget to open the outside spigot to drain the remaining water. - Source: Internet
  • If you are merely repairing or replacing your main water line and not the valve, an alternative to trenching is trenchless water line replacement. This method costs between $75 and $150 per linear foot. It generally involves inserting a new pipe between where the water line connects to your home and where it connects to the city line, then filling it with resin to form a stronger pipe. - Source: Internet
  • For those with propane or liquefied petroleum gas, there’s a main shutoff valve on the tank itself, and usually a main shutoff valve somewhere before the first appliance. Some valves (both gas and water) manufactured before 1980 contain a lubricant to help the valve seal better and operate more smoothly. In many cases, this lubricant will have hardened or reacted with the gas to make the valve difficult to turn. Applying gentle heat with a hair dryer and working the valve open and shut in stages will usually free it up again. Sometimes you need to use a pliers to free the stuck handle. - Source: Internet
  • You’ll notice this story contains a lot of “oftens,” “usuallys” and “almost always’s.” That’s because valves vary greatly in location, shape and number, depending on the age of your house, the local codes and which part of the country you live in. This article covers the basics of each system. - Source: Internet
  • If you can guarantee to have the fix completed quickly, then a pipe freezing kit (such as this one for example) can shut off water in a pipe temporarily by creating a frozen “plug”. These kits are great for professionals who can get the job done rapidly and have all the right tools and parts to hand. As a DIYer though, you can usually expect jobs to take longer than you expected. I would 100% recommend not using a pipe freezer for any repairs you’ll be doing, because there is an extremely high risk of the pipe unfreezing while you’re working and filling your basement with a couple of inches of water! Do it the safe way instead, and drain the system down. It’s much better to regret a bit of time and some aching muscles than to regret Katrina-style flood damage. - Source: Internet
  • If your plumbing system lacks supply stops, install them when you shut off the main valve to repair a sink, toilet or appliance. Eventually you’ll have supply stops at every fixture, and your family won’t yell at you every time they see you with a wrench in your hand. Remember, fixture supply stops must be easily accessible; you can’t drywall or plaster over them without installing an access panel to reach them. - Source: Internet
  • For example, the shut off valve for your toilet will be entirely different from the valve for your laundry machine. One valve will be smaller and built with the ability to quickly connect with your toilet supply line. Whereas the other will be much larger and equipped with hammer arrestors to prevent the detrimental effects of water hammer. - Source: Internet
  • Expect to pay around $40 for a replacement main water shut-off valve. You’ll need to know the type of valve and plumbing you currently have. If you need to rent a trencher or excavator to reach a buried valve, you may pay more than $1,000 in rental costs. Obtain all necessary permits and take great care when digging, as you don’t want to damage the water line. - Source: Internet
  • If the water trapped between the spigot and supply shutoff valve freezes, it can burst that section of pipe. Since there’s no water flowing through this short damaged section of pipe, there are no obvious leaks or sign of damage—yet. But when you turn the supply valve back on in the spring and pressure returns to that pipe, the burst section of pipe will leak like crazy—and often go unnoticed for hours or days. One plumber told me he’s made dozens of repairs dealing with this mistake. - Source: Internet
