Installation & maintenance tips
- Before installation, wipe clean both mating surfaces to remove debris that could compromise the seal.
- Align the collar so the adjustable portion sits evenly around the sump opening, then snug the connection to secure alignment.
- After assembly, run the system briefly and inspect for leaks; re-tighten if necessary to maintain a reliable seal.
- Periodically inspect the collar during routine pool maintenance to ensure the fit remains secure over time.
