If the pressure is between 40 and 60 psi, there is no need for a regulator. However, if the water pressure is over 80 psi, it is probably causing excessive stress on pipes, fittings, and fixtures.

This is due to the water pressure regulator, or pressure-reducing valve, that manages the water pressure in your home. It's not always necessary, but it is needed for homes that receive water with ...

This regulator prevents water pressure from spiking in the home (usually no more than 40 to 60 PSI). Most regulators are adjustable, so it may be that the regulator is set too low.

Then, install your pressure gauge on an exterior faucet, turn on the faucet and read the pressure. Your home’s water pressure should be between 40 and 80 psi (pounds per square inch).

The typical inlet water pressure to a home is about 40 to 45 psi. Normally, it should not exceed 60 psi. The pressure regulator is usually preset to 50 psi.

At the lower end of the pressure range, the spring loses sensitivity; at the high end, the spring nears its maximum capacity. Regulators use either a piston or diaphragm to sense downstream pressure.
