Client called us out due to their 50 gal Rheem nat gas water heater that was 4 yrs old was leaking at the bottom. Rheem did a warranty swap out and we got new 50 gal tall nat gas water heater installed in the old ones place. Installed up to code, with new expansion tank with proper support, and new ball valve shutoff, as well as new copper piping and new gas piping at the unit itself. Clients home water pressure is right at 80 psi, safe range is 50-79 psi. High water pressure will cause any type of plumbing issue on the water system possible, ex. Running toilet, dripping faucet, dripping shower head, pipe leaks, etc. Due to customer declining to have the high water pressure addressed by replacing the failed pressure reducing valve, work we did today we cannot warranty. NO WARRANTY DUE TO KNOWN HIGH WATER PRESSURE
