Venturi Pinhole Design for Extra Cleaning Power — Pops Up Fully Even on Variable-Speed Pumps
The Gamma Series 4 Venturi (G4V) Pop-Up Head from Pentair In-Floor (A&A) is built for pools that need extra cleaning muscle. Unlike the classic adjustable Gamma 4, the Venturi uses pinholes on top of the head to pull in additional water, giving you a stronger, boosted flow that reaches the spots a standard head leaves behind. It's a Gamma 4-generation head, so it drops straight into your existing Gamma 4 collars — and the improved spring means it still pops up fully even when your pump is dialed down to low RPMs.
KEY FEATURES
- Venturi Cleaning Boost: Pinholes on the top of the head draw in extra water for a stronger flow — ideal for hard-to-reach areas and pools that need more cleaning power than a standard head delivers.
- Patented Dual Laminar Nozzle: A 3/8" inner and 7/16" outer nozzle create a focused, laminar cleaning path for the Venturi's patented cleaning boost. (Note: the Venturi is a fixed-flow head and does not use the four-in-one adjustable nozzle found on the classic Gamma 4.)
- Improved Spring for Variable-Speed Pumps: Pops up fully even at lower RPMs — full cleaning coverage on your energy-saving pump speeds. A big win for anyone who's upgraded to a variable-speed pump.
- Secure Fit, Larger Locking Tab: A larger locking tab grips the collar tighter for a stable, secure fit, so the head stays seated instead of working loose mid-cycle.
- Drops Into Existing Gamma 4 Collars: A true direct replacement — no plumbing changes needed.
- Easy Diagnosis & Installation: Use the Plastic or Metal Gamma 4 tool for quick install or removal — go with the Metal tool if you're fighting an old head that's stuck in its fitting.
- Light Gray Finish: Blends cleanly into gray and darker pool surfaces for a low-profile look.

FREQUENTLY ASKED QUESTIONS
What's the difference between the Venturi (G4V) and the classic Gamma 4 head?
The Venturi uses pinholes on top of the head to draw in extra water, creating a stronger, boosted flow for hard-to-reach areas. The classic Gamma 4 instead offers a four-in-one adjustable nozzle. The Venturi is a fixed-flow head and does not adjust — choose it when you want maximum cleaning power rather than tunable flow.
Will the Venturi head fit my existing Gamma 4 collar?
Yes. The Gamma Series 4 Venturi is a Gamma 4-generation head and drops straight into your existing Gamma 4 collars, so it's a direct replacement with no plumbing changes.
Does this pop-up head work with a variable-speed pump?
It does. The improved spring lets the head pop up fully even at lower RPMs, so you get full cleaning coverage on your energy-saving pump speeds.
Does the Venturi have an adjustable nozzle?
No. The Venturi uses a fixed 3/8" inner and 7/16" outer nozzle for a laminar cleaning path with its patented boost. If you need adjustable flow, choose the classic Gamma 4 Adjustable Flow head instead.
Which installation tool should I use?
Either the Plastic or Metal Gamma 4 tool will install and remove this head. If you're dealing with an older head that's stuck in its fitting, go with the Metal tool for extra leverage.
Is this a genuine Pentair (A&A) part?
Yes. This is a genuine Pentair In-Floor (A&A) replacement head, SKU 231202 (formerly 567630), and it ships free within the U.S.
