Pentair 170022 FNS Plus Tank Lid | 60 SF

The most common reasons your filter leaks can be from a worn, cracked, or warped filter lid. Replacing the lid of your filter is an easy and cost saving fix. Especially, when purchasing an OEM replacement like Pentair 170022, saving you the hassle that comes with most aftermarket brands.

With most generic filter lids they do not always have the specifications of the original manufacturer (Pentair)and may not seat correctly. The Pentair 170022 is manufactured using Pentair’s specifications and this can make a difference when dealing with filter pressurization. Furthermore, if a filter lid does not fit correctly it can cause air leaks, water loss, and unsafe operating conditions and using OEM parts can save you from this problem.

Pro Tip: When replacing a filter lid it is best to replace the lid O-ring before seating the lid. If you install the new lid with a worn or brittle O-ring it can still leak. Also, it is important to lube the O-ring

The best use for pool owners with this lid is for Pentair 180009 FNS Plus 60 square foot DE filters. Especially, if they have issues with leaking, cracks, and holding pressure. In most cases the filter body may not have issues and the lid material is worn from sun exposure.
