I just put in a brand new gas hot water heater and at first it appeared
everything went smooth, then two hours after installing it, I saw a
somewhat strong flow of water coming out of the T&P valve. I then ran
back to Home Depot and bough a new T&P valve and even turned down the
temperature to about 90 degrees. Then overnight I saw a lot of water
came out of the new T&P valve once again.
After browsing through this group and doing some research, it appears I
might have too much pressure coming from the public water. But I'm
surprised because I never had this problem on my old hot water heater.
Both of the valves are the same (I believe 170 PSI or 205 degrees)
A few questions:
1) Is there a possibility I could have a defective water heater? It's
a 40 gallon GE 6year that I just purchased from Home Depot. I'm on my
second T&P valve.
2) Why didn't I have this problem on my old hot water heater? (they use
the same T&P Valve)
3) If this is the case, can I get away with just installing a pressure
reducing valve, or will I need an expansion tank as well.
Thanks for any help!
