What is an automatic shut off valve?
An automatic water shut-off valve is designed to take the guesswork out of turning off the water in your home. It’s installed at the apex to your household plumbing system, where the entire water supply can be shut off.
When to turn off a leaking water heater?
If you find that your water heater has developed a leak, you should turn off the water via the valve on the heater to minimize leakage. If, however, the valve is broken, you must turn off the main water supply to prevent a never-ending flood. Here are some potential causes for a leaking water heater:
What causes a pressure valve on a water heater to leak?
If the gauge shows the pressure is at 150 psi or greater, excessive water pressure is probably causing your pressure valve to leak. But if the leak is active while the pressure is normal, the water pressure in your plumbing system probably isn’t causing it.
What does it mean when your water heater valve is off?
The ‘Off’ position on the gas valve dial only means that it will not heat the water. The pilot light is still on and gas from the main supply line is still on. You need to turn the inline valve ninety degrees so that it is perpendicular with the gas line. Next you want to run some hot water into a sink until the water cools down to lukewarm.
What to do if your hot water tank is leaking?
That depends on whether the pressure relief valve is leaking around the threads where it attaches to the hot water tank or if it is leaking out of the inside of the valve itself. In either case, start by replacing the pressure relief valve, using a different brand in case the valve itself is defective.

Where is the cold water shut off valve on a water heater?
Locate and close the cold water shut-off valve entering the water heater. This is usually located directly over the water heater. It will either be a ball valve or a gate valve. For a gate valve, turn the valve clockwise to close.
When does a water heater pressure relief valve open?
If at any point the temperature or pressure reaches an unsafe level, the water heater triggers the relief valve to open and release water out of the tank until the temperature and pressure return to normal. Reasons for water discharging from the relief valve
