Pentair 14965-0028 Plug / Rotor with Gasket Assembly for Sta-Rite 1-1/2″ Multiport Valves
The Pentair / Sta-Rite 14965-0028 is an OEM replacement plug/rotor with gasket assembly used in select 1-1/2″ Sta-Rite multiport backwash valves. This internal valve component helps seal and direct water flow between valve positions (Filter, Backwash, Rinse, Waste, Recirculate, Closed). Replacing a worn assembly can restore proper sealing and reduce internal bypass or leaking to waste.
Common Compatibility (Verify Before Ordering)
- Sta-Rite / Pentair 1-1/2″ multiport valves (select models)
- Often referenced in parts catalogs as a plug & gasket assembly or rotor with gasket
- Common alternate references include STA-061-5822 / 4679-12 (seller/catalog dependent)
Multiport valves vary by size and generation. Always confirm your exact valve model and parts diagram before ordering.
What This Part Does
- Directs water flow internally as the multiport handle is moved between positions
- Provides sealing between internal valve ports via the attached gasket
- Helps prevent cross-porting (such as water leaking to waste while in Filter)
- Restores smoother, more reliable valve operation when the original rotor/plug is worn
Common Signs You May Need Replacement
- Water continuously leaking to the waste line while the valve is set to Filter
- Poor filtration/backwash performance caused by internal bypassing
- Visible wear, tearing, deformation, or separation of the gasket on the rotor/plug assembly
- Valve operation issues after confirming handle/top assembly is functioning properly
Installation Notes
- Turn off the pump and relieve all filter pressure before servicing the multiport valve.
- Mark the valve position and take photos before disassembly to ensure correct reassembly.
- Inspect the valve cover O-ring and other internal seals while open; replace worn parts as needed.
- Clean the valve body sealing surfaces thoroughly before installing the new rotor/plug assembly.
- After reassembly, test valve positions and check for leaks or unwanted flow to waste.

Maintenance Tips
- Never change multiport valve positions while the pump is running.
- If the handle gets stiff, inspect for debris/sand intrusion before forcing the valve.
- Backwash and rinse as needed based on pressure rise from your clean starting baseline.
- Inspect internal valve seals during seasonal service to catch wear before it causes bypassing.
