Product details
The Pentair 170020 is the tank lid for the FNS Plus 36 square foot DE filter, model FNS36. It is a new genuine Pentair part.
What it is
The FNS Plus tank is built in two halves held together by a band clamp. This is the upper half, the domed lid that carries the air relief and clamps down onto the tank body. It is not the full tank and it does not include the filter internals.
When you need one
Filter tops live outdoors under constant pressure cycling. Over the years the plastic crazes, and once the surface is crazed or cracked the lid begins to seep, usually near the clamp line. Tightening the clamp harder does not fix it and can make the crack worse. Replacing the lid is the repair.
Before you order
Match the model on the tank label. FNS Plus is sold in several square footages and the lids are specific to each size, so a 36 SQFT lid will not seat correctly on a larger tank.
