While homeowners can make minor adjustments to existing regulators using the adjustment screw on top of the unit, we recommend professional service for safety and warranty reasons. Incorrect adjustments can damage your plumbing or void manufacturer warranties.
If you choose to adjust it yourself, you’ll need a pressure gauge and should make small quarter-turn adjustments while monitoring the pressure. Turn clockwise to increase pressure, counter-clockwise to decrease it.
However, if your regulator needs repair, replacement, or if you’re experiencing significant pressure problems, professional service ensures proper diagnosis and prevents costly mistakes that could damage your entire plumbing system.
