Emergency or not, the moment the sink drips or the faucet starts leaking, it could become a disaster unless you act on it. Don't delay it till the emergency ukase comes! Know it now, and save yourself all the nervous moments later.
What Is The Main Water Shut Off Valve?
The main water shut-off valve governs every drop of water into your entire house. Whenever it is turned off, one stops the inflow of water to all fixtures: sinks, toilets, showers, etc. Think of it as the master switch for your plumbing system.
Most of the time, this valve is somewhere:
- Near the water meter
- In the basement if the climate is cooler
- In the garage or utility room, or near the foundation if the climate is warmer
Step-by-Step Guide: Turning Off the Main Water Shut Off Valve
This is the safe and precise way to do it:
- Locate the Valve
The search will be somewhere near where the water line enters into the house. More often than not, the main water shut off valve is usually found indoors, very near to where the main pipe comes from the outside. - Identify the Type of Valve
You'll normally see one of two types:
- Ball valve: Turn it a quarter turn clockwise.
- Gate valve: Rotate it clockwise until it won't turn anymore. - Closing the Valve
Close it gently but firmly. If it hasn't been turned for years, it may have rusted a little. If it isn't turning, don't force it! Consider some penetrating oil. - Test by Opening a Faucet
After you have closed the valve, open the hot or cold water faucet to check if there is any water flow. If water is stopped, then you have successfully turned off the water supply to your house.
What You Should Know About Outside Water Shut Off Valve
Most older homes have an outside water shut off valve near the street. Typically, this valve is found in a box buried in the ground with a metal or plastic covering over it and denoted as "Water" or "Meter".
Usually, it is in the city. But in some amazing cases, like having a house valve break, you might need to shut this one off. It can be tricky, though; perhaps you might require a special tool like a water key or valve wrench, or tamper with it becomes illegal according to local codes.
Water main valve VS other valves
The water main valve is one of those valves which is often confused with other shut off valves found in the home. In difference, it is as follows:
- Water mains valves all shut off water to the house.
- Fixture specific valves (under sinks, toilets) only shut off water to that fixture.
- Shut off valves for outside irrigation systems work only to shut it down.
So when you have a problem, don't mess with the wrong valve.
