No, 65 PSI (pounds per square inch) is not too high for residential water pressure and is generally safe for modern plumbing systems. While 50 to 60 PSI is widely considered the optimal sweet spot for balancing vigorous shower performance with plumbing longevity, 65 PSI falls well within the acceptable code limit under 80 PSI. However, if your home features older, fragile piping or delicate fixtures, you may want to adjust your pressure reducing valve slightly downward toward 60 PSI. Verification: Check your pressure gauge reading against manufacturer limits for connected appliances.
