How do I adjust the relief setting?
First, remove the chrome hex plug with a 7/8”combination wrench, etc and set aside. This gives you access to the
relief set screw (5/16” hex). Turning the set screw clockwise 1 turn will increase the pressure ~300psi [20.7bar].
Can I paint my valve? – Painting valves is okay as long as the all ports are properly plugged.
Pipe thread sealant – Warranty is void when Teflon tape is used to seal pipe threads. This is because Teflon tape is a friction
reducing agent which allows customers to over-torque fittings. We recommend using a sealant that does not include friction
reducing agents i.e. Lead Plate.
