Water pressure that is too high entering a home can lead to ruptured pipes and damaged fixtures. More pressure than you actually need also creates unnecessary costs and waste in water consumption. The solution is a pressure-reducing valve, also known as a water pressure regulator. These valves reduce the force of water flow from city mains and regulate the amount of pressure you receive, preventing fluctuations.
If you hear banging pipes, experience an unusual number of leaks and/or have water splashing out of your sink, your water pressure may be too high. The best way to slow and regulate pressure is with a pressure reducing value. Your local plumber can tell you if you have excessive pressure.
