Product details

The Pentair 190037 is the standpipe assembly for the 60 square foot PacFab FNS DE filter. It is the genuine Pentair replacement part.

What the standpipe does

Inside a DE filter the grids surround a central standpipe. Water is pushed through the DE coated fabric, and the clean water that comes out the other side collects in the manifold and travels up the standpipe to the filter outlet. Everything depends on that path staying sealed.

When to replace it

If the standpipe cracks, splits or the seat wears, unfiltered water takes the shortcut and goes straight out the outlet. The tell is DE powder returning to the pool after a fresh charge, or a filter that never builds normal pressure. Replacing the standpipe restores the seal that forces water to go through the grids.

Questions and answers

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

Will this fit any FNS filter?
It is the 60 square foot version. Filter size is printed on the tank label, so check it before ordering, because the other FNS sizes use different standpipes.
Is it a genuine Pentair part?
Yes. It is Pentair OEM, part number 190037.
Why would the standpipe need replacing?
A cracked or split standpipe lets water go around the grids instead of through them. The usual symptom is DE powder coming back into the pool through the returns.
Does it include the grids?
No. This listing is the standpipe assembly. The DE grids and the manifold are separate parts.
