I had the same problem. Mine was cured when I installed an expansion tank on the cold water line running into the water heater.

I replaced my old hot water tank about 2 years ago because no one I called could not get the overflow pipe to stop leaking, even after replacing the valve twice! Within 2 weeks of installing the new one…it started leaking too. As I forestated, that was 2 years ago…and it is still leaking. I am really frustrated about how to stop this leaking. The valve has been replaced on this once, and as of today, a plumber, who is a friend of ours lowered the pressure…?? and within an hour after he left, the leaking started again! What else can I do?? Thank you.

Hi Eduardo,
Unless it’s leaking substantially, replacing your temperature pressure relief valve shouldn’t have an effect on water pressure.

I have attempted to change the TPR valve b/c it has a slow leak, I have followed all the steps, however I am unable to remove(unscrew) the TPR valve. I had a 250lb man use his weight and a pipe wrench to try and remove the valve in order to replace it with a new one. A cheater won’t work b/c that 250lb man bent the relief valve drain pipe threads. Can I try to use WD-40 or some other trick of the trade to get the TPR valve off w/o damaging anything?

I had a leak from pressure valve which finally just blew across room. I replaced valve but when I turned the main water valve back on only upstairs water runs. I didnt turn anything else off but the gas and delmarva told me how to do that. for three days I have no water on 1st floor, but have water in basement and second floor. Help!

Maybe from now recommend turning the main supply line off. Today we changed a relief valve on a heater in an attic. The plumbing had been crossed. The shutoff was on the cold inlet side of the heater but the cold water was coming in to the hot side. Dip tube changed and c and h crossed. Not good is a understatement. Just an idea but thats how I will approach it from now on. Turn off main. Real fun going behind a sorry plumber
