Pentair 261055 2-inch Side-Mount Multiport Valve (Triton / Quad Filters)
The Pentair 261055 is a high-flow, 6-position side-mount multiport valve designed for use with Pentair sand filters (like Triton / Triton II) and D.E. filters (such as Quad series). It provides all essential filter functions in a single, durable valve body — making filter operation and maintenance simple and reliable.
Key Features
- 2″ side-mount multiport valve — compatible with standard 2″ plumbing for both sand and D.E. filter systems.
- Six operating positions — filter, backwash, rinse, waste, recirculate, and closed — plus a winterize position for off-season shutdown.
- Positive-lock handle mechanism — ensures secure, accurate position changes without over-rotating.
- Durable PVC construction — chemical- and corrosion-resistant for long life in swimming pool environments.
- 7.5″ centerline dimension between filter ports — designed to match many Triton and Quad filter housings for straightforward installation.

Installation & Usage Tips
Before installing, ensure your filter tank plumbing matches 2″ pipe and that port alignment corresponds with valve ports. Align the valve handle in the correct position before starting the pump. Always turn off the pump before changing positions to avoid damage. For winterizing or seasonal shutdown, use the supplied winterize/closed position to isolate the system and prevent freeze or debris ingress.
