Product details

The Pentair 400006 is the lid and locking ring assembly for the XF Series pumps, covering both the WhisperFlo XF and the IntelliFlo XF variable speed models. It is the genuine Pentair part.

What the lid does

The strainer pot has to hold a vacuum for the pump to stay primed. That job falls to the clear lid and the ring that clamps it down. When the lid crazes, cracks or stops seating flat, air works its way in, the pot will not fill and the pump runs noisy and dry looking even though the valves are open.

Buying it as an assembly

Lid and ring are sold together here, which avoids the common problem of a new lid meeting an old ring that has gone brittle at the threads. Turn the ring down by hand only, since overtightening is what splits rings in the first place.

Questions and answers

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

Which pumps does this fit?
The Pentair XF Series: WhisperFlo XF and IntelliFlo XF variable speed pool pumps.
Does it include the locking ring?
Yes. Pentair 400006 is supplied as the lid and locking ring assembly.
Does the lid o-ring come with it?
The facts list this as the lid and locking ring assembly. The pot o-ring is ordered separately if yours is flattened or cracked.
Why would the pump lose prime through the lid?
A lid that is crazed, cracked or no longer seating flat lets air into the strainer pot. The pump then draws air instead of water and the basket will not stay full.
