Our Expert Verdict: Real-World Results You Can Trust
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.
Expert Comparison & Pro Tips
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

How does the Pentair 170022 FNS Plus Tank Lid compare to aftermarket filter lids?
Most aftermarket filter lids may appear to be identical but they can often have problems. These problems can lead to the top not seating right, which can cause leaking and pressure loss. They also do not have the same factory specifications or durability.
The Pentair 170022 is an OEM part and was manufactured using Pentair's exact specifications for the original filter. Also, using OEM replacement parts ensures that your newly replaced filter top will have the same long lasting durability as your original filter. The best option is to use OEM replacement parts for safety, performance, and hassle free installation.
