Reduce the Pressure
Pressure regulator valves (PRV) regulate household water pressure and diminish the force of water being sprayed from you irrigation system. Pressure regulator valves are located at the water service entry point, near the main shutoff valve.
PRVs can reduce misting and cut water usage outdoors by 20%. Lower pressure increases the life of you irrigation system by decreasing wear on pipes, valves, and sprinklers. Check your water pressure annually with a water pressure gauge. Water pressure should be 50-60 pounds per square inch (psi). If it is higher than 80 psi, your PRV may be failing, or you may not have a PRV.
When purchasing a new pressure regulator valve ensure that it meets the American Society of Sanitation Engineer Standards. PRVs can be found online or at your local hardware store.
To install, follow the manufacturer’s instructions or call a plumber.
