Hi, The Tank Lid Assy., 520 (after 11/98) (178582) would be the tank lid needed for the Clean & Clear Plus 520 Filter.

I have a 25,000 gal salt water pool. It measures 20'W x 33'L x 5' D (avg.). What model Pentair Cartridge Pool filter would be best for my pool?

A  Answered on 12/13/2016 by InyoPools Product Specialist Lennox H.

Hi, Leonard. We will also need the flow rate of your pump to determine what size filter you'll need. To calculate the flow rate of you pump you can follow the steps in our How To: Size a Pool Pump guide.

My Pentair clean and clear model 520 tank, top/bottom o-ring needs replaced and I can't tell from this diagram which o-ring I should order . can you advise? Thx

A  Answered on 6/12/2018 by InyoPools Product Specialist Hector F.

The body o-ring for your model filter is listed at key number 10 on the parts diagram listed here. There are two types based on year of manufacture. If you are not sure of that then you can call Pentair at  1-800-831-7133 with the serial number of the filter so they can confirm for you.

Ordered the 520 at a great price and timely delivery. I disconnected the plumbing from the old one and discarded. I plumbed the pvc and then finished installation of new filter with new cartridges. I tightened all of the fittings and the pool is running smooth.

Were these instructions helpful?
