How High Water Pressure Can Damage Your Home’s Plumbing System


Everyone dreads taking a shower or washing their car with low water pressure, but the soothing luxury of sufficient water pressure doesn’t come without a cost to your wallet or your home. For every 10 minutes of water use, high water pressure can waste 6 to 26 gallons of water, which can result in a pricey water bill. In fact, high water pressure also puts excess stress on your home’s plumbing system and reduces the life expectancy of appliances like dishwashers, washing machines, and water heaters.

Water Pressure: How High Is Too High?

In general, residential water pressure is considered too excessive at or above 60 pounds per square inch (PSI). For most plumbing appliances and systems, the ideal water pressure is somewhere between 45 and 55 PSI.

Can High Water Pressure Damage Pipes?

Yes, high water pressure can erode pipes, causing:

  • A greater risk of pipes cracking or breaking
  • Leaks and disruptive sounds
  • A reduced service life for both your pipes and your plumbing fixtures

3 Signs of High Water Pressure

Your home’s water pressure may be too high if you notice:


  1. Banging pipes: Excessive pressure can cause water to thrash through pipes quickly, causing knocking or banging sounds.
  2. Running toilets: Though uncommon, high water pressure can cause toilets to run continuously.
  3. Leaking faucets: If your faucet leaks at certain times of the day or when using a plumbing fixture, high water pressure may be to blame.
