Temperature Pressure Valve leak

I just tested the temp pressure valve for the first time in a few years. Now it has a tiny trickle that won't stop. Anybody have this happen?

Is this for a hot-water heating boiler or a domestic hot-water heater? Heating boilers normally have a pressure relief valve, not a T-P.

Assuming this is a boiler, what does the pressure gauge indicate?

If your relief valve is leaking when the pressure is normal, it should be replaced - with one of the same type and of sufficient relief capacitiy.

It is a boiler and the pressure is normal, in fact it leaks when the boiler is not even hot.

It only began leaking after I tested it, but I suppose its time for a new one. Thanks.

I would replace it with a new one. This may require draining the system.

Boiler safety valves should be replaced every five years even if they "seem" okay. What you might be able to do is to open the valve by pulling the handle and flushing some water through the valve for at least a full second and then letting the valve snap shut. Be sure the "make-up water" is turned on when doing this test.
