What is a water pressure regulator?

A water pressure regulator is a safety feature designed to prevent the water pressure inside your home from climbing too high or falling too low. Building codes require builders to install a water pressure regulator on homes when the street mainline pressure exceeds 80 psi (pounds per square inch). Most regulators are pre-set by manufacturers at 45 to 60 psi, which is the optimal pressure.
