To adjust water pressure in your house, locate the pressure valve, and tighten or loosen the adjustment screw on the valve to increase or reduce the water pressure respectively. Check the supply line to ensure it has enough pressure before attempting this task.
First, gather a screwdriver and a wrench. Once the necessary tools are in place, start by locating the pressure valve and the adjustment screw on it. The valve is usually located at the water meter, which typically is found in the basement of the house, in the utility room or under the kitchen sink.
After locating the valve, use the wrench to loosen the locknut and facilitate the turning of the adjustment screw. To increase the water pressure, tighten the screw by turning it clockwise, slowly and carefully in order to prevent water leakage.
Reducing the water pressure, on the other hand, involves loosening the screw by turning it counterclockwise. Check the result of the adjustment by turning on the house faucets and assessing the effectiveness of the adjustment, and repeat the process as needed until you achieve desired results. If the pressure does not change despite the adjustments, replace the pressure valve with a new one.
