Yes, having high water pressure in your house is very bad and damaging to your plumbing infrastructure. Water pressure exceeding 80 PSI violates standard plumbing codes and places extreme, continuous mechanical stress on water heater tanks, appliance supply hoses, washing machine inlet valves, toilet fill valves, and faucet cartridge seals. This relentless stress drastically increases the risk of sudden pipe joint leaks, pinhole leaks, and catastrophic indoor flooding. Verification: Use a pressure test gauge to confirm your home operates safely between 50 and 60 PSI.
