- Use when the valve handle becomes hard to shift, leaks when under pressure, or the piston is worn or damaged.
- Compatible with pool filter systems where a 2″ slide valve controls backwash, rinse and filter modes.
Features & Specifications
- Includes piston shaft, packing, O-rings and mounting hardware for a full internal rebuild.
- Designed for durable performance in pool chemical environments and repeated cycle use.
- OEM replacement part ensuring correct fit and factory specifications.
Installation Notes
Turn off pump and relieve system pressure. Remove valve handle and cover, extract old piston and shaft, clean valve body interior thoroughly, and install new assembly per the kit instructions. Re-assemble the valve, restore pressure, and check for smooth operation and absence of leaks through the valve body.
Maintenance Tip
During annual service inspect the valve handle, piston movement and packing area for wear or signs of leakage. Replacing the piston assembly at the first sign of stiffness or seepage will help maintain flow integrity and extend the life of the valve body.
