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.

Compatibility and specifications

Fitment note: This kit is for the larger FullFloXF check valves listed above. Check the part number on your existing valve or its parts diagram before ordering. It is not the replacement assembly for the smaller Pentair 2-inch check valve, part 263042.

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.

No. Part 270119Z is a repair kit for the internal check valve assembly. The plumbed-in valve body is not included.

Will it fit Pentair check valve 263060?
Yes. Pentair lists 270119Z with its 2½-inch / 3-inch FullFloXF check valve family, which includes 263060.
