Where is My Shut off Valve?

Do you know where to find the water shut-off valve if you need to turn the water off to your entire house? Knowing how and where to shut off your home’s main water supply is as important as knowing how and where to turn-off or reset an electric breaker or replace a fuse. Learn where your main shut-off valve is inside your home, have it plainly marked and operate it at least annually to ensure it is in proper working order. It is also a good idea to show this valve to any of your children you feel are responsible enough to utilize the valve in your absence.

Age of Your Home

Older homes obviously also have old shutoff valves that probably will fail; however, newer homes and buildings sometimes have shutoff valves that will also malfunction. The failure of modern shutoff valves can be a result of several things:

new water line
  • Poor brass material
  • Leaky solder joints
  • Internal parts poorly made

Every new home is required to have a main water shut-off valve installed inside the home during initial construction. Typically, they are located close to where the water service line enters your home and are usually near the water meter. Our area has older homes built prior to this requirement. In those cases, shut off valves may not even be inside the house but rather outside where yard growth may cover its location. If your home does not have an internal shut off valve call us and we can quickly remedy this problem.

There are also underground shut-off valves installed at the property line. This shut-off is typically referred to as the “curb-stop”, which is protected by and accessed through a “curb-box”.

For most emergencies or repairs, shutting-off the proper inside valve is essential. With this valve, you can shut water off for the entire house. Your home will also have shut off valves for specific areas of your home such as an exterior faucet, or an irrigation system. Private Water Shut-Off Valves will look different based on the home’s age. Older homes may have a round handle where newer homes will have a lever. If your home has the old style, you should consider having it upgraded to a lever which are far less likely to experience leakage.
