Electric water heater TPR valve leaking


The water pressure is at 62LBS PSI the TPR is 210 Degrees & 150 PSI...It seem strange but maybe the new valve is bad?

I seriously doubt that it's the TPR valve. Do you have a pressure gauge plumbed into your system or are you putting a gauge on your hose bib? Does it leak when you have a hot water faucet open and running or just when there's no hot water running?

If you have a hose bib pressure gage put it on the drain line at the bottom of the heater and see what the pressure is inside . Be real careful though we're talking real hot stuff. If you get no reading the line might be clogged. DANGER.

the water pressure is about 60psi until the heater kicks in then it rises over 100psi (my gauge only goes to 100psi) triggering the T&P valve
why such a huge jump in pressure (yes I know...heat) but it takes almost triple the resting pressure to trip the T&P valve?
again it just started a week ago?

Did you get 60psi at the drain valve on the tank or somewhere else?

How can you tell that its your elements turning on that's raising your pressure?

How quickly is your gauge moving from 60 to 100+psi?

When my pressure reducing valve went bad it appeared to be working when someone was using water in the house, but as soon as all the taps were closed the system would climb from 60psi to 160psi in about 5sec.

Fingers crossed..it's the pressure reducing valve. The guy at Ace says they are selling 10 week in our area becouse the water company has increased the pressure (they deny it) and our houses are all older (my valve may be 50+ years old). any hoo the new one is installed and the heat spike was only about +20lbs it was +90lbs before in less than 5 minutes.

I will report back tomorow to see if we are back to normal?
