How to Correct Surging Water Pressure

When water pressure abruptly goes up and down, it is known as surging pressure. Surging pressure is caused by a number of factors inside your home and around your neighborhood. Appliances that use water, such as dishwashers or laundry machines, can drain the pressure on your system and cause water pressure to surge in other areas of the house. Sprinkler systems can also lead to surging pressure as zones turn on and off. New construction in your neighborhood can also cause water pressure to surge. There are steps you can take to minimize the impact of surging water pressure.

      Adjust the timer on your automatic sprinklers to run during times of the day that no other water is being used in your home. Turn the dial on the timer to the "Set Time" function and enter a time when minimal water use is occurring, such as late at night or early in the morning.

      Run your laundry and dishwasher at different times. Running both appliances at the same time will contribute greatly to surging water pressure.

      Call your local utility provider and ask if it is aware of surging water pressure in your area. Often, water utilities will be aware of the cause of surging water pressure. Ask the customer service representative when the problem will be solved and if there are times of the day that are best to run water-using appliances.

      Check the setting on your water pressure regulator. All homes have a regulator installed along the main water line. The brass cone-shaped device changes the raw inlet pressure from the utility lines outside the home, which is typically very high, to the normal pressure range of between 45 psi and 55 psi to the downstream pipes in your home. This is preset by the manufacturer. The regulator is adjustable, and can be set between 50 psi and 70 psi. You need a pressure gauge on a downstream faucet to get a measurement of the psi. Use a wrench to loosen the locking nut around the base of the regulator and turn the adjustment stem clockwise to increase or counterclockwise to reduce with a wrench.
