Product details

This is the genuine Pentair 170016 tank bottom assembly for the FNS36 Plus DE filter. It is the lower half of the filter tank, supplied as an assembly.

What it does

The tank bottom holds the grid assembly and takes the full working pressure of the filter. It is not a part that wears out gradually. It gets replaced when it cracks, splits at a seam or leaks under pressure, and a cracked tank half is not something to patch.

Before you order

Confirm your filter is the FNS36 Plus. The FNS Plus range covers several tank sizes and the bottoms are not interchangeable between them.

Questions and answers

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

Which filter is this for?
The FNS36 Plus. Tank halves are sized to the filter, so a different FNS Plus size needs a different part.
Is it a genuine Pentair part?
Yes. It is the Pentair OEM tank bottom assembly, part number 170016.
Do the grids come with it?
No. This is the tank bottom assembly. Grids, the manifold and the o-ring are separate parts.
Why would I need one?
Most often because the lower tank has cracked or is leaking. A cracked tank half cannot be patched reliably under pressure.
