Hi, I've a Bradford white gas water heater in my house. The heater is about 9 years old. I've not done any maintenance on the heater till now. I live in Washington state.
Sequence of events
1. Before leaving for a short vacation, I turned the water heater to pilot mode.
2. Within a day since vacation, the water pressure shot up from 55psi to 105psi.
3. We are back from vacation, and the pressure is back to normal, after I opened one of the water taps, thereby relieving the water pressure. Now, I've started investigating the reason for the jump in water pressure.
4. I tested the Thermal expansion tank, and it seems good, since it is releasing air (no water coming out) from its valve.
5. Next, I'm testing the T&P valve in water heater as per here:
6. I pulled the T&P valve, and water started coming out of drain pipes. But also, water squirted on the T&P valve itself, which I was not expecting. Is that normal?
7. Now, the hot water draining from T&P valve's drain pipes doesn't stop. The water is coming out of drain pipes for the last 2 hours and still draining. I was expecting this to stop.
Can you please suggest, on how to troubleshoot and fix this issue, where the drain pipes from T&P valve doesn't stop flushing water?
