Q: How to find and shut off main water shutoff valve?

A: Main Water Valve: If you have a basement, it will likely be located on the front foundation wall and will have a large, metal handle. If you don’t have a basement, your shutoff valve could be near the water heater, by your washer and dryer or under the kitchen sink. Also, if you have a crawl space, the valve could be there.¹

Q: Is there a sensor that can detect water?

A: Water sensors detect and prevent excess moisture and flooding caused by broken pipes and faulty appliances. A leak detection system is made of sensors, shut-off valves and a centralized hub. The sensors are placed in areas where leaks are common, such as near faucets and beneath water heaters.

Q: How do you fix a water shut off valve?

A: Clogged Valve. Test the “street-side” valve where the water enters the house. … Loosen the Old Valve. Check out the electrical system “bonding jumper” that runs from a clamp on the house side of the meter to a clamp on the street side. Install the New Valve.
