Did you know the average life expectancy of a pressure reducing valve is 3-5 years? A PRV adjusts the high water pressure that comes into your home to a lower, safer level. The recommended pressure setting for a household PRV is from 60 to 70 pounds per square inch.
Think about the water that comes out of a fire hose. It is running fast and furious at a high pressure. Now think about a high force of water like that coming into your home and imagine the damage it could cause to your system. A PRV helps regulate that water pressure. High water pressure can result in leaks, pipe damage and wasted water.
If you haven't replaced your PRV lately, it might be time.
