Product Description

Installation Notes

Installation should be performed by a licensed plumber or certified backflow prevention technician in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure fully before disassembling any backflow preventer components. Inspect the valve body seat for damage before installing the new check assembly and O-ring. Do not overtighten the cover, as this can distort the O-ring and compromise the seal.
