Product details

The Pentair T40FG is an automatic pool filler that uses a Fluidmaster valve, supplied in grey.

Why a pool needs one

Evaporation, splash out and backwashing all pull water out of a pool, and the level drifts down whether anyone is watching or not. An autofill takes that job over. It holds the water where you set it, which keeps the skimmer at its working depth and keeps the pump from drawing air on a pool that has quietly dropped an inch too far.

The valve

The unit uses a Fluidmaster valve, the same style of fill valve used in millions of installations, which makes it a familiar item to service.

Questions and answers

What people ask about this product, answered by our pool techs.

What does an autofill do?
It watches the pool level and opens a water valve to top the pool up when it drops, so the level stays where you set it.
What valve does it use?
A Fluidmaster valve.
Why does the pool level matter?
If the water falls below the skimmer mouth the skimmer stops working and the pump can start drawing air, which risks losing prime and running the pump dry.
Is this a genuine Pentair part?
Yes. It is Pentair part T40FG.
