Find Your Master Water Valve

  • Phone:
If you ever have a line break inside your home (or if you want to check for a leak), you need to know where your master water valve is located.
There are three most likely locations:
  1. Where the water supply pipe enters your home, apartment or business
  2. Near your clothes washer hook-up
  3. Near your water heater

To make sure you have found the right valve, try turning it off briefly then check each one of your faucets by turning them on to verify that no water comes out. If water stills flows the valve you turned off is not the master water valve, try again. Mark the master valve clearly, with a tag, bright ribbon or paint so anyone can find it in an emergency.
