Pentair G4 Head Adjustable Orifice with Riser

This assembly is specifically designed for Pentair G4 in-floor cleaning systems. Before purchasing, verify that your current cleaning heads are the G4 style, as they are not universally interchangeable with other Pentair models or older cleaning systems.

The adjustable orifice allows you to fine-tune the water flow coming out of the head. By tweaking this setting, you can balance the cleaning pressure across different zones in your pool, ensuring debris is pushed effectively toward the drain.

Yes, this is a complete assembly that includes both the G4 cleaning head and the riser. It is designed to be a direct drop-in replacement for units that are no longer rotating or popping up correctly.

Most pool owners can replace these heads without professional help. You typically just need the specific removal tool designed for Pentair G4 heads to unscrew the old unit and thread the new one into place.

The adjustable version is ideal if you have specific areas of your pool that aren't getting enough cleaning power or if you need to reduce pressure in certain zones to prevent surface erosion. It gives you more control over your pool's circulation pattern than a standard fixed head.
