Product Overview

The S1 Internal HF Gray Cleaning Head | 236353 is a high-flow internal pop-up cleaning head designed for compatible A&A Manufacturing / Pentair In-Floor Cleaning & Circulation pool systems.

This Style 1 high-flow head is built for strong floor-zone cleaning performance. The large 7/16" high-flow orifice helps create a powerful jet of water that sweeps debris across the pool floor while improving water circulation. As the system cycles, the head rotates through 12 positions to provide full 360-degree cleaning coverage.

Finished in gray, this replacement head is a strong choice for pools with gray, dark gray, pebble, or neutral interior finishes where a lower-profile appearance is preferred.

Benefits

The S1 Internal HF Gray Cleaning Head helps restore cleaning power to compatible in-floor pool systems. When pop-up heads become worn, stuck, clogged, or damaged, debris may collect in dead spots and the pool may require more manual brushing or vacuuming.

This high-flow head helps improve water movement across the pool floor with a larger orifice designed for stronger cleaning action. The rotating pattern helps spread the water jet across the surrounding area, improving coverage and helping the in-floor system perform as intended.

For pool owners and service professionals, replacing worn heads is a simple way to improve system performance without replacing the entire in-floor cleaning system.

Installation Notes

Turn off the pool pump and relieve pressure before servicing the in-floor cleaning system. Use the correct Style 1 cleaning head removal tool to remove the existing head from the floor body.

Inspect the body, O-ring, locking tabs, and surrounding floor fitting before installing the new head. Make sure the replacement head seats fully and locks into place. After installation, restart the system and confirm that the head pops up, rotates, and retracts properly.
