How do I replace my water pressure regulator?

If you’re handy, you can save the few hundred dollars a professional plumber will charge you to replace your water pressure regulator by doing it yourself.

  1. Turn off the main water supply to your house. Run a faucet to empty out all water pipes.
  2. Use a wrench to remove your existing regulator, which is located next to the main water valve shutoff inside your home.
  3. Install the new regulator, adding caulk as necessary to ensure an airtight fit.
  4. Once everything is reinstalled, turn the main water supply back on and run a faucet for approximately 30 minutes, checking for leaks near the newly connected regulator.

Some regulators may need to be switched on prior to operation. If you encounter difficulty, call a plumber for professional advice.
