Product details
The Pentair 170017 is the tank bottom assembly for the FNS Plus 48 square foot DE filter, model FNSP48. It is the genuine Pentair part.
What the tank bottom is
An FNS Plus filter is a two piece pressure vessel clamped together at the belly band. The bottom half carries the internals and takes the working pressure of the system. When it cracks, usually from freeze damage or age, the filter cannot hold pressure and the filter is out of service until the half is replaced.
Size specific
The FNS Plus family runs in several square footages and the tank halves are not shared between them. This is the 48. Read the model off the label on the filter and confirm FNSP48 before ordering.
While it is apart
Replacing a tank half means stripping the filter, which is the moment to look at the grids, the manifold and the seals. Those are separate Pentair numbers and it is far less work to do them now than to open the filter twice.
