Here is a guide to shutting off your main water valve in an emergency.
Situations That May Require Shutting Off the Main Water Valve
- Burst Pipes: Over time, your pipes can burst due to corrosion or water pressure changes. In this case, water can spread rapidly and damage walls, floors, and belongings.
- Major Plumbing Leaks: Any kind of severe leak originating under your sink, behind your walls or from your shower can cause catastrophic water damage. Shutting off your water supply may be the only way to stop water flow until your emergency plumber arrives.
- Overflowing Toilets or Appliance Failures: Overflowing toilets, failed water heaters, or leaking washing machine hoses can create emergencies that require a water valve shut-off.
How to Locate Your Main Water Shut-Off Valve
Each home is different, and your water shut-off valve could be located in a few different places. Being aware of its location before an emergency occurs is extremely important and will help you act quickly in any emergency situation, limiting water damage.
The shut-off valve is usually located in the basement of the home, in the utility room. However, some homes have exterior shutoff valves near the foundation or property line.
Step-by-Step Guide to Shutting Off the Main Water Valve
- Identify the Type of Valve: There are gate valves and ball valves used in plumbing systems. Gate valves usually need to be rotated a few times to turn off the water supply, whereas a ball valve requires a quarter turn.
- Turn the Valve Off Properly: If you have an older plumbing system, you’ll need to exercise caution when turning valves so you do not damage them. Rotate the valve slowly and confirm that the water supply is off.
- Test That the Water Is Off: Open a faucet to check whether water flow has stopped.
What to Do After the Water Has Been Shut Off
If you haven’t already, call in your local water leak detection specialists once your water is off. You should also move any valuables away from affected areas to keep them safe in case of any residual water fall. Try to avoid turning the water back on until your emergency plumbers arrive.
