Quick, there’s a major water leak! Where is the turn-off valve? Sounds like a simple test, and it is unless the test occurs when water is pouring from the leaking pipe.
That is not the time to go on a water -valve treasure hunt.
Every teenager and adult living in the home should where the main water shut-off valves is located. Knowing where the main water valve can be found is the key to averting catastrophe when it comes to plumbing emergencies. Being familiar with the location of the valve and how to turn it off will save money, time, and headaches in the case of a water disaster.
Water meters are typically located outside, attached to the side of the house. Some meters have two valves, in which case the one closest to the house will be the correct one to turn , when attempting to cut water flow.
Some homes will have an outside meter but no valve. Following the pipe extending from the meter to the house will usually reveal the valve. The other possibility is a valve located inside the home. This valve will be found on the water pipe where it enters the house (most commonly placed on the ground floor or in a basement.) Water valves are usually placed near the wall and within easy reach.
It is easy to tell if the correct valve has been located and turned off, because water flow from all pipes in the home will cease.
Isolation valves located at each fixture or servicing an entire bathroom or kitchen can stop the flow of water to that location and water will continue to service the remainder of the home.
A final hint- the shut off valve will not be located under a sink or on the hot water heater. Turning the hot water valve will only stop the hot water from running through the pipes. For those living in a condo, it is good to know that the shut off valves to all condos may be lined up in a row.
Inspect and test the main and isolation valves every year for operation and possible leaks. Never store items in front of a valve. If you ever have a water problem, it’s nice to know exactly where to go to stop the flow.
