Product Overview

The S1 Internal LF White Jet | 236251 is a low-flow internal pop-up cleaning head designed for compatible A&A Manufacturing / Pentair In-Floor Cleaning & Circulation pool systems.

This Style 1 low-flow head is commonly used where a smaller, controlled water jet is needed for proper zone balance. The 1/4" low-flow orifice helps direct water through the in-floor cleaning system while supporting controlled circulation and debris movement. As the system cycles, the head rotates through 12 positions to provide full 360-degree coverage.

Finished in white, this replacement jet is ideal for pools with white, light plaster, quartz, pebble, or light-colored interior finishes.

Ideal For

• A&A / Pentair in-floor cleaning systems
• Style 1 pop-up head replacements
• Low-flow cleaning zones
• Step, bench, spa, and detail cleaning areas
• MagnaSweep and JetSweep style systems
• Replacing worn, stuck, cracked, or missing cleaning heads
• Balancing in-floor cleaning zone flow
• White or light-colored pool interior finishes
• Professional pool service repairs
• In-floor cleaning system maintenance

Benefits

The S1 Internal LF White Jet helps restore proper flow and cleaning action in compatible in-floor pool systems. When a pop-up head becomes stuck, damaged, clogged, or worn, the system may lose cleaning coverage and water distribution in that zone.

This low-flow version is useful when the system requires controlled water output rather than a stronger high-flow jet. It helps maintain balanced distribution across multiple cleaning heads, especially in steps, benches, spas, shelves, or areas where too much flow may disrupt system performance.

For service professionals, replacing the correct low-flow head helps keep the in-floor cleaning system operating according to its original hydraulic design.

Specifications

Included Components

• 1 × S1 Style 1 Low Flow Internal White Jet

Cleaning head tool, body, collar, O-ring, in-floor valve parts, and additional system components are sold separately unless specifically included by the supplier.

Compatibility Notes

This cleaning head is intended for compatible Style 1 / S1 low-flow internal in-floor cleaning systems.

Common compatibility references include:

• A&A Manufacturing Style 1 systems
• Pentair In-Floor Cleaning & Circulation Style 1 systems
• MagnaSweep systems using Style 1 heads
• JetSweep systems using Style 1 heads
• Jet Clean / Quick Clean Style 1 applications
• Former part number 521406

Always confirm the existing head style, color, orifice type, flow type, body style, and part number before ordering. Low-flow and high-flow heads are not always interchangeable because the system may be hydraulically balanced for a specific orifice size.

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.

If the head does not pop up or rotate correctly, inspect the in-floor valve, zone pressure, pump flow, filter condition, debris in the line, and cleaning head body.
