I have a Pentair FNS Plus 60 square ft filter part # 180009. Looking to replce with a cartridge filter. Can you provide recomendation? Would I need to replace the multi valve currently being used with the Pentair filter?
Hello John - Thank you for contacting Inyo. You can replace the Pentair FNS 60 with a Pentair Clean & Clear 520. The Clean & Clear 520 is a quad cartridge filter. The cartridge filter does not require a valve. You could remove the old valve when you plumb in the new filter.
Thank you for the information.
