Hi All,
Im wondering if I need to install an expansion tank on my water heater, but I'd like to hear your thoughts first regarding the issue I've been experiencing.
The house is 125 years old (I've lived here 2 years). The plumbing (copper) is from the late 70's, and is still in decent shape. We're on rural water and there is no PRV on the incoming water line (at least not in the house). The water heater is a 40 gallon Richmond propane (6G40-32PF1).
Ever since living here, we'll get an occasional 2-3 second surge (on both hot and cold lines). I've finally pinpointed that it only seems to occur after running a decent amount of hot water (think a hot shower, or extended use of kitchen sink hot water). After shutting off the water to the shower, for example, you can go to any other faucet in the house, and the handles give some operational resistance and the surge occurs once opened.
I tested the pressure last year while in its non-surge state, and it registered 55 PSI.
This plumbing setup has been in place for many decades (excluding the water heater which is 10+ years old), so it can't be too terribly damaging, but I do have occasional drips from some faucets after shutting off (from what I can only assume is due to the occasional overpressurization of the system).
Any thoughts on what my issue may be?
