Relief Valve

Why does water heater relief valve is leaking?

My water heater is 7 years old and the pressure relief started to leak. I tried flushing the water heater, and lowered the water temperature, but it’s still leaking.

Flick it a couple times and see if it’ll reseat and stop leaking. If it doesn’t, replace it.
