When to Replace

• If the rotating collar becomes stuck, cracked, or difficult to turn.
• If the threaded base shows signs of stripped plastic or stress fractures.
• If the unit fails to maintain a proper airtight seal, resulting in loss of suction power for the cleaner.

Installation Tips

• Ensure the pool pump is turned off before removing the existing fitting.
• Clean the pool wall suction port threads of any debris or old sealant tape before installation.
• Hand-tighten the fitting into the wall port; do not overtighten with tools to avoid cracking the plastic.
• Apply a thin layer of pool-safe silicone lubricant to the threads if the fit is excessively tight.
• Verify the safety spring mechanism functions properly by inserting and removing the hose before turning the pump back on.
