Water Pressure Regulator Valve Adjustment

Step 3 adjust the screw.

Water pressure regulator valve adjustment.

Pressure reducing valves are designed to reduce incoming water or steam pressure to a safer constant predetermined downstream level. Depending on the type of valve the downstream pressure is established by a pressure adjustment setting on the valve or by an external sensor. Depending on your location and distance from the municipal water source incoming pressure can range from 80 pounds per square inch psi to 150 psi. A water pressure regulator is a dome shaped brass fitting that generally is found just past the main shutoff valve where the main water line enters the house.

Too much pressure can damage your pipes and lead to leaks and water waste. The home water pressure regulator reduces the amount of water pressure entering the home from a municipality.

The valve is made of brass and has a bell shaped midsection with a medium sized screw at the tip. If you didn t have a pressure reducing valve installed between the municipal water system and your house the water pressure would break.
