Installation & Component Swap

Step 1 (Prep): Unthread old Air Relief Valve and Pressure Gauge. Clean all male threads with a rag and remove old debris or Teflon tape.
Step 2 (Sealing): Apply 2-3 wraps of PTFE tape clockwise to the valve threads and 3-4 wraps to the gauge threads. Lubricate the valve O-ring.
Step 3 (Assembly): Hand-tighten components into the new lid center port. If the gauge is crooked, add tape layers rather than over-tightening.
?? Pro-Tips for a Perfect Seal
  • The O-Ring Secret: Always clean the main tank O-ring and apply non-petroleum (PTFE) lubricant to ensure a vacuum-tight seal and easy removal later.
  • Inspect the "Seat": Run your finger along the rim of the bottom tank half; a single grain of sand can prevent a perfect seal.
  • Startup Safety: Keep the Air Relief Valve open during startup. Stand back until a steady stream of water purges all trapped air.
  • Chemical Caution: Avoid storing corrosive pool chemicals next to the tank, as fumes can weaken the thermoplastic over time.
Essential Components: Requires Tank Body O-Ring, High-Flow Manual Air Relief Valve, 0-60 PSI Pressure Gauge, and Locking Ring Nut (sold separately).

Safety Warning: Explosion Risk-Never remove the lid while the pump is running. Sized strictly for 50/100 sq. ft. tanks; will not fit 125, 150, or 200 sq. ft. models.
