The great thing about pressure reducing valves is that they're set to regulate your water flow to a specific pressure. That means if there's a sudden spike in your area's municipal water pressure, the spring and diaphragm in the valve will tighten and you'll still have a consistent amount of pressure in your home. PRVs are effectively multi-functional - by lowering outlet pressure and flow rate, they also help reduce excessive water consumption and plumbing noise. Many valves have a nut, screw, or knob attached to them that allow you to do the actual adjusting. Turning the screw or knob clockwise typically increases the water pressure while turning it counter-clockwise lowers the pressure. We do not recommend adjusting your pressure reducing valve if it is over a year old.
Normal psi for a home pipe system is between 30 and 80 psi. While you don't want the psi to be too low, it violates code to be above 80. Instead, you should aim for a psi that's between 60 and 70.For most houses, 80 psi (pounds per square inch) is about right. If the water pressure is over 100 psi, that's too much. High water pressure puts a lot of unnecessary strain on your home's plumbing system. This often leads to loosened joints, pinhole leaks in the pipes, dripping faucets, shower heads, running toilets, burst wash machine hoses or icemaker lines. Left unrepaired, leaking pipes are likely to cause mold growth and other serious water damage to your home. @TappPlumbing
