Regularly testing the pressure can help catch any regulator problems before excessively high pressure damages your plumbing.

What Is the Ideal Water Pressure?

Water pressure is measured in psi, or pounds per square inch.

Most building codes consider anything over 80 psi too high.

Look out for a hose fed by a large pipe, about 1/2 inch to 1 inch in diameter.

Turn off any washing machines, sprinklers, refrigerators with ice makers, and dishwashers.

If the reading is below 40 psi, call your water supplier to investigate the low water pressure.

Screw the pressure gauge onto the faucet, then launch the faucet all the way to test the pressure.

This regulator is a bell-shaped rig attached to the pipe where the water supply enters your home.
