Product Overview

This inlet/outlet fitting is used in compatible vinyl liner pool wall installations as a connection point between the pool interior and the circulation plumbing. Depending on the system design, the fitting can support water return to the pool or function as an outlet point for water movement through the plumbing system.

The fitting is commonly installed during new liner pool construction, liner replacement, wall fitting service, or renovation work. Because vinyl liner wall penetrations are critical sealing points, proper installation is important to help prevent leaks and maintain the integrity of the pool wall and liner.

During installation, the liner, wall panel, gasket surfaces, plumbing connection, and fitting alignment should be inspected and prepared carefully. Hardware should be tightened evenly to help create consistent sealing pressure without pinching or distorting the liner.

Routine maintenance should include checking the fitting face, surrounding liner area, and plumbing connection for leaks, cracks, looseness, or signs of wear. Maintaining the wall fitting in good condition helps support proper circulation, water containment, and long-term pool system performance.
