A water pressure regulator is a plumbing valve that reduces the water pressure coming from the main water line into the house.o determine if you need a water pressure regulator test the water pressure of the main water supply to your house. You can buy a pressure gauge for a local hardware or home improvement store.
Regulators reduce the pressure from a supply pressure to some other desired operating pressure. They do this independent of supply pressure and flow. So, whether a gas range is on low or on high, the pressure on the outlet side of the regulator will be the same. 2.hese regulators can be installed at individual appliances, or used as line pressure regulators. A line pressure regulator refers to regulating the gas pressure from pounds to inches of water columnat a manifold or central location.
