A Guide to Water Shut-Off Valves in and Around Your Home

When water starts flowing where it shouldn’t, time is everything. A quick water valve shut-off can save your home from costly damage. That’s why every homeowner should know how to locate and operate key water shut-off valves throughout the house.

Below, we’ll walk you through finding the main water shut-off valve, understanding how individual shut-off valves work, and knowing what to do in an emergency water shut-off situation.

Know Where Your Valves Are

The main water shut-off valve controls water to your entire house. It’s typically located near your water meter—either outside near the curb or inside in a utility area. If you’re not sure how to turn off the water to your house, this is the first place to start. Turn it clockwise to shut off the supply.

Also, locate and test:

• Toilet shut-off valves (behind the toilet)
• Sink shut-off valves (under bathroom or kitchen sinks)
• Washing machine valves (on the wall behind the unit)
• Water heater shut-off valve (usually on the cold water pipe leading into the top of the tank)

For added protection, consider installing an automatic water shut-off valve that detects leaks and shuts off water automatically.
