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.
A water pressure reducing valve, also called a water pressure regulator, is designed to reduce incoming main water pressure levels in order to protect plumbing system components and reduce water consumption.or example, a good quality 3/4â³ pressure reducing valve costs between $100 to $150. Larger sizes cost more. If homeowners are unsure if they need a replacement, we can perform a water pressure reducing valve inspection. If we determine there is no need to repair or replace the valve, our fee is $70.
