Why is my Water heater leaking in TPvalve?

Answer 1

Like any mechanical device, T-P valves (temperature/pressure relief valves) do have a finite life, and must eventually be replaced. Most have a small lever you can move to test them. When you lift the lever, the valve releases hot water as if it had tripped. Sometimes you can use the test lever to dislodge debris that is preventing the valve from completely closing. Try a couple of short blasts. If you try this, make sure that you and other persons are clear of the discharge pipe! Hot water willshoot out, and can seriously burn anyone standing in the path of the water. If this doesnt stop the leak, call a qualified plumber and have the valve replaced. This is a safety device, don't skimp on doing it right!
