Where to find your water shut-off valve

Your main shut-off valve is usually where the water line enters the house: in the basement on the wall facing the street, or near the water meter or well pressure tank. Turn it clockwise, or a lever a quarter turn, to stop the water.

Your main shut-off valve is usually where the water line enters the house: in the basement on the front wall, near the water meter, or next to the pressure tank if you're on a well. Knowing where it is turns a burst pipe from a flood into a mop-up.

Where to look

A private wellOn the pipe beside the pressure tank, usually a blue or grey tank in the basement

How to turn it off

  1. A round wheel handle: turn it clockwise until it stops.
  2. A lever handle: turn it a quarter turn so it sits across the pipe, not along it.
  3. Open a faucet on the lowest floor to drain the water left in the pipes.
  4. On a well with no valve you can find, switch off the well pump at the electrical panel.
