To adjust a water pressure valve, locate the pressure valve and the adjustment screw, and loosen or tighten the screw to reduce or raise the water pressure as required. Replace the pressure valve if the problem persists.Continue Reading
Start by locating the water supply meter usually situated in the basement beneath the water sink or in a utility room. Locate the pressure valve, which is a brass device that is bell-shaped in the middle and features a medium-sized screw at its tip. Before the adjustment, check the supply line to ensure that it has enough pressure.
Once you have located the pressure valve, unscrew and remove the lock nut with a wrench, use a screwdriver to either turn the adjustment screw clockwise to tighten and increase water pressure, or counter clockwise to loosen and reduce the pressure. Work slowly and frequently check the pressure as needed to prevent excessive pressure that may result in leaks and running of the toilets.
Examine the faucets and showers to ensure that the pressure is properly controlled and there are no leaks. In case of any leaks, replace the faulty valve with a new one to prevent any further damage. For full valve replacement, consult a trained plumber.Learn more about Plumbing
