The pressure release valve on your water heater tank is another common place of indoor leaks. The valve is a brass fitting threaded into the tank and is most often located near the top of the tank.
Look for signs of water around the valve or even on the floor around the water heater. If the pressure release valve is leaking, water may drip down the side of the tank and onto the floor. If you find a leaking pressure release valve on your water heater you should repair it immediately.
These are just some common places of leaks inside the home. These are not the only places leaks can occur. Leaks can also occur on dishwashers, ice makers, washing machines , or plumbing pipes, just to name a few.
Leaks can also occur outside the home. Check outdoor water spigots, sprinkler systems and swimming pools. In any case, if you can’t find and repair the leak yourself, call a professional plumber.
