Polaris 9-100-1116 Replacement Diaphragm Valve Kit
Part # 9-100-1116 — a replacement valve diaphragm kit designed for use with many Polaris pressure-side pool cleaners and booster pump systems. This kit restores proper water flow and suction by replacing worn or leaking internal valve components.
Key Features
- Includes the primary diaphragm and internal sealing components required to refurbish the cleaner’s valve assembly.
- Designed to restore correct one-directional flow and maintain suction strength for efficient cleaning performance.
- Helps eliminate leaks, loss of suction, or erratic cleaner behavior caused by degraded or cracked valve components.
- Cost-effective repair kit — extends the life of the pool cleaner without needing a full replacement.
Typical Applications
Used when a pressure-side pool cleaner shows signs of poor suction, reduced coverage, back-flow, or inconsistency in movement. Also recommended as a preventive maintenance measure when the cleaner has seen heavy use or when the valve appears worn.
Installation & Compatibility Notes
Disconnect the cleaner from the booster pump and release all pressure. Remove the valve housing and carefully discard the old diaphragm and seals. Clean the valve interior thoroughly, install the new diaphragm and sealing components, reassemble the valve housing, reconnect the system, and test for correct suction and flow before allowing the cleaner to operate normally.
Why Choose This Valve Kit?
The 9-100-1116 diaphragm replacement kit allows you to restore proper valve function, improve suction performance, and prolong the useful life of your Polaris pool cleaner — all at a fraction of the cost of replacing the entire unit.
Maintenance Tips
- Inspect the valve components annually for wear or deformation, especially if the cleaner is used frequently.
- Replace the diaphragm kit at first signs of cracking, leaks, or loss of suction.
- Ensure all internal surfaces are clean and free of debris before installing new seals to maintain proper sealing.
- Test the cleaner after repair to verify suction strength, hose integrity, and proper cleaning coverage before leaving it unattended.
