New 50 gal AO Smith gas WH which is leaking small amounts of water out of the T&P valve.
- I'm getting normal pressure reading of 50 lbs, with a max pressure reading 160 lbs.
- I installed a new 2 gallon Everbuilt expansion tank which has 45 lbs of pressure.
Would a larger expansion tank or changing the pressure solve this problem? Could there be something wrong with the WH?
Solution: I finally noticed there is an inline check valve installed between the WH and the expansion tank. Looks like the plumber installed it when the recirculation pump was installed and the expansion tank has been a decoration ever since.
