Product Overview

The Pentair 236703 Dark Gray G2V Venturi Retro Cleaner Head Internal is a genuine Pentair/A&A replacement cleaning head designed for compatible Style 2 / Gamma Series 2 in-floor pool cleaning systems.

The G2V Venturi design utilizes the flow of water through the cleaning head to enhance surrounding water movement, helping move dirt and debris across the pool floor while improving overall circulation.

Part 236703 installs into an existing compatible Style 2 floor fitting, allowing the removable cleaning-head internal to be replaced without replacing the permanent fitting installed in the pool shell.

The dark gray finish is well suited for darker plaster, pebble, quartz, and other coordinating pool interior finishes.

Benefits

G2V Venturi Design

The G2V designation identifies this cleaning head as the Venturi version of the Gamma Series 2 system.

As pressurized water exits the cleaning head, the Venturi design helps draw surrounding water into the flow pattern. This creates additional water movement around the cleaning head and assists in moving debris toward the pool's main drain or designated collection area.

Properly operating in-floor cleaning heads can help improve:

• Pool-floor circulation
• Debris movement
• Distribution of sanitized water
• Temperature distribution
• Cleaning around steps and benches
• Reduction of stagnant areas

Specifications

Pentair currently identifies 236703 specifically as the Dark Gray G2V Retro Internal within its Style 2 cleaning-head product family.

Available G2V Retro Colors

Pentair offers the G2V Retro Internal in several colors:

Warranty & Compatibility

Style 2 / Gamma Series 2 Compatibility

The 236703 is designed for compatible A&A Style 2 / Gamma Series 2 floor fittings.

This replacement allows an existing Style 2 system to use G2V Venturi cleaning-head technology without replacing the permanent floor fitting when that fitting remains in good condition.

Style 2 heads are not interchangeable with Style 1 or Style 1.5 systems, so the existing cleaning-head style should always be confirmed before ordering.

G2V vs. Standard G2

The 236703 is a G2V Venturi cleaning head, not the standard G2 variable-flow version.

For the standard Dark Gray G2 Retro Internal with variable-flow orifices, Pentair lists 236683.

These are separate cleaning-head designs and should not be treated as the same replacement.

Installation Notes

Before replacing the cleaning head:

• Turn off the pool pump.
• Relieve pressure from the circulation system.
• Verify that the existing fitting is Style 2 / Gamma Series 2.
• Remove the existing internal using the proper Style 2 installation/removal tool.
• Inspect the floor fitting for debris, cracks, or damage.
• Install the new G2V internal and make sure it locks securely into position.
• Restart the system and verify proper cleaning-head operation.

The commonly used Style 2 / Gamma Series 2 installation and removal tool is Pentair Part Number 229642.
