Inside a water pressure regulator has a variable spring loaded diaphragm that automatically widens and narrows depending on the amount of.

Water pressure regulator valve adjustment.

See the illustration at the top of this page and at left. Step 3 adjust the screw. Step 2 find the valve. It usually has an adjustment screw on top.

How to adjust the psi on a water pressure reducing valve. If you didn t have a pressure reducing valve installed between the municipal water system and your house the water pressure would break. The valve is made of brass and has a bell shaped midsection with a medium sized screw at the tip. A water pressure regulator or pressure reducing may be installed.

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. The home water pressure regulator reduces the amount of water pressure entering the home from a municipality. 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. Test your pressure after each incremental turn by turning on faucets and shower heads and flushing toilets.

Depending on the type of valve the downstream pressure is established by a pressure adjustment setting on the valve or by an external sensor. Make sure that your supply line has sufficient pressure before adjusting the pressure valve itself. It may seem like a pain to test your fixtures after each tiny adjustment but these small adjustments can make a lot of difference in the pressure. To set your water to your preferred pressure you need to adjust the pressure regulator valve.

The pressure regulator valve is usually located on the water supply line either in your basement or crawlspace or in the box with your water meter. Pressure reducing valves are designed to reduce incoming water or steam pressure to a safer constant predetermined downstream level. Once you have found the water meter locate the valve. Too much pressure can damage your pipes and lead to leaks and water waste.
