Product overview
Restore the internal check valve assembly on a compatible Pentair FullFloXF valve with the Pentair 270119Z Check Valve Flapper Replacement Kit. Designed for the larger FullFloXF check valves, this kit provides the service parts needed to replace a worn or damaged flapper assembly while retaining a sound valve body and existing plumbing.
A properly working flapper opens with normal water flow and closes to help prevent reverse flow. If the flapper is damaged, sticking, or failing to seal, inspect the valve and confirm the model before ordering this repair kit.

Service guidance
Turn off the pump, isolate the plumbing where possible, and relieve system pressure before opening the check valve. Inspect the valve body and sealing surfaces while the cover is removed. If the body is cracked or the plumbing connections are damaged, replacing the internal assembly alone will not correct that problem. Reassemble and test the valve according to Pentair’s instructions.
