My house is about 8 years old. All original plumbing and 50gal natural gas hot water heater.
About 3 months ago, one morning after taking a shower, the whole house filter I have near the meter in my basement burst.
I had a plumber come out to replace the broken filter system with a new one. He said while he was there, he noticed the pressure was a bit on the high side (70ish) and backed it down to 50 using the PRV.
Since that day we experience very high pressure after running the hot water (shower, dishwasher, clothes washer, etc). The way we noticed is that now after using the hot water, our kitchen sink and our shower head would drip until we opened a faucet somewhere to relieve the pressure for about 10 seconds. In the 7 years of being in the house prior to this day, we never had a problem with the pressure.
Last night I bought a pressure gauge and ran a few tests:
I ran only cold water for about 5 minutes. Shut everything off and checked the pressure. It held steady at about 45psi.
I ran only HOT water for about 5 minutes. Shut everything off and checked the pressure. It started out at 45psi and about 10 minutes later was over 160psi!
I do NOT have an expansion tank near my water heater (or anywhere, for that matter).
It seems that adding an expansion tank would solve the problem. Does that seem right?
And if so, can anyone explain why all of a sudden we have this problem? Why did we not have this problem for the prior 7 years?
Any help would be greatly appreciated.
Thanks!
