Product Overview
The S1 Internal HF White Cleaning Head | 236351 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 creates a powerful water jet that helps sweep dirt and debris across the pool floor while improving circulation. As the system cycles, the head rotates through 12 positions to provide full 360-degree cleaning coverage.
Finished in white, this replacement head is ideal for pools with white, light plaster, quartz, pebble, or light-colored interior finishes.

Benefits
The S1 Internal HF White Cleaning Head helps restore cleaning performance to compatible in-floor pool systems. When pop-up heads become worn, stuck, clogged, or damaged, debris may collect in low-flow areas and the pool may require more manual brushing or vacuuming.
This high-flow head improves water movement across the pool floor with a larger orifice designed for stronger cleaning action. Its rotating pattern helps distribute the water jet around 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.
