Was running washing machine. I noticed a drip from 50 gallon WH- TRV valve.
Around the same time I tested pressure upwards of 100 in the house.
We do not have PRV valve. Water pressure in area is usually consistent at 60.
I removed 2 gallon expansion tank, it was 10 psi lower than it should be and I pumped it up. All seemed good, multiple tests of pressure with water heater running and directly after running and pressure never changed.
A few days later, same thing happened as before. When the pressure was high, I quickly tested my neighbors outdoor spigot and it was spot on 60 while mine was much higher. I let my faucet run for awhile and retested and the pressure had lowered.
Since my neighbors pressure was ok at the same time and the fact that my pressure lowered after running a facuet for a bit I assume my expansion tank was the issue. I replaced with a larger 4 gallon tank. WhenI removed old I noticed it was still holding that 60 psi charge that I pumped it up to a few days later.
Do you feel I made a logical decision to replace tank?
ie: drip from TRV (only a year old) and water pressure was high. I don't think its the valve in that case.
No need to install PRV since neighbor was normal while I was high....
Since my pressure seemed to have gone up after using washer and the fact that the pressure decreased after running water for a while, Im guessing its something within my house...
So if its in the house, what else could it be besides the thermal expansion tank? What else causes high pressure within the home besides thermal expansion or increase pressure in the main?
If it happens again... what would you do? Add a PRV?
