Installation & Compatibility Notes
Before installation, cut and prepare the wall opening to accept the long-body return fitting. Insert the fitting body into the pool wall ensuring the flange is flush with the interior surface. Thread the 1 ½″ male inlet into the corresponding return port, and solvent-cement the 1 ½″ slip side to the PVC plumbing. After installation, pressurize briefly to check for leaks, then finish with the pool surface. It’s particularly suited for thick-wall applications found in gunite or concrete pool construction.
Maintenance Tips
- Inspect the fitting face and flange at each seasonal service for cracking, flange separation or signs of leakage.
- Ensure the slip-joint connection remains properly solvent-cemented and that the threads remain secure to avoid air-ingress or loss of prime.
- Keep replacement body in stock as part of service inventory for renovation or thick-wall retrofit jobs — it helps reduce downtime when upgrading or repairing return plumbing.
