We replaced the pressure regulating valve on the main water line for a beautiful home in Taylors, SC. The pressure for the home was dropping to nothing when a faucet was turned on. After the valve was replaced, the tubs, showers, faucets, and toilets ran much better. There are typically tho ways pressure regulators go bad. 1. The regulator will completely shut down the flow when the water is turned on , or 2. The regulator will fully open to allow dangerous levels of pressure to be on the system.
