Quick overview
- Pentair part 274416Z The factory center diverter for the FullFloXF backwash valve.
- Center position Pentair lists the inlet and outlet diverters as separate parts, so confirm which one has failed.
- Stops port to port bypass A worn diverter lets water cross between ports, which shows up as backwash water in the return line.
- Genuine Pentair The OEM part rather than a generic diverter of approximate fit.
- Serviceable valve The FullFloXF diverters are replaceable, so a leaking valve does not have to mean a whole new valve.
- Inspect the set together If one diverter has worn, the others have seen the same hours, so check them while the valve is open.

Product details
The Pentair 274416Z is the center diverter for the FullFloXF backwash valve. It is the genuine Pentair replacement part.
What the diverter does
A backwash valve works by routing flow between ports, and the diverters are what seal one path off from another. As they wear, the seal stops being tight and water begins to slip past. The result is a valve that never quite commits to a position, so you get dirty backwash water reaching the return line, filter pressure that will not settle, or a slow leak to waste while the system is in filter mode.
Which one to order
Pentair sells the FullFloXF diverters individually, with separate parts for the inlet, center and outlet positions. This listing is the center diverter. Since all three see the same running hours, it is worth inspecting the others while the valve is apart rather than opening it twice.
