55000 gals having trouble keeping pool clean algae builds up on walls what size filter do i need gone through a couple now is there a filter bigger than 520 thanks

A  Answered on 11/17/2021 by InyoPools Product Specialist Rich N.

Hi Jay, it sounds like your filter is properly sized for your pool.  Generally, lack of chlorine is the biggest reason to have algae.  Maybe your stabilizer (CYA) level is too high, making the chlorine ineffective.  Your pool may not be as green as the pictures in our article on Why Is My Pool Green?, but I recommend reading that as well as our article on How to Clean a Green Pool?.  We would also recommend getting a good, reliable test kit like this Taylor Water Test Kit FAS-DPD - K-2006 to get accurate readings of your pool's chemistry.

I have a 36,000 gallon pool with a 1HP Hayward pump. Am looking to switch away from D.E. Should I go with 420 or 520 sq.ft. cartridge filter?

A  Answered on 4/23/2021 by InyoPools Product Specialist Craig C.

Hello Brian.  The Pentair Clean & Clear Plus 520 Cartridge Filter would be the more appropriate selection.  This filter has 520 square feet of filter area and is rated for pools of this size.  A 420 square foot cartridge filter is rated for pools more in the 20,000-gallon range.  Additional note:  for a pool of 36,000 gallons the pool circulation pump is undersized at 1 HP.  ( other factors may have influenced this pump selection that are not apparent in this information ) In the future, if you choose to upgrade to a larger pump size, the 520 sq. ft. filter can accommodate up to a 2.0 HP pump.  Clean & Clear Plus 520 Cartridge Filter - 160332

Replacing a sand filter with pentair 420 or 520. Don't know which one to buy? Pool, 19,000-23,000 gals(approx) in ground/raised jacuzzi. A 3 HP, Pentair intelliflo pump manufactured in 2012. Pool cleaner tell me to go with 520. Pool company who does replacements states 420 more than enough. i know filters are 40% less for 420 but in a 3-5 year replacement cycle,not enough to be concerned about. Pool in nort Scottsdale,at 2,800 elevation. we don's get sandstorms as they do lower in the valley.

A  Answered on 12/16/2020 by InyoPools Product Specialist Hector F.

Hi Ethan, as long as you meet or exceed the gallons per minute(GPM) rating that your sand filter has in the new filter then you are good to go. If you are not sure of that specification then please use this guide we put together called "How To Size a Pool Filter" that should assist.

how do you drain the pool using a pentair 160332 filter

A  Answered on 10/26/2020 by InyoPools Product Specialist Hector F.

Hi Dwight, in order to drain water out of a swimming pool with this filter you will need to remove the drain cap that you can see on this Pentair Clean & Clear Plus Cartridge parts diagram on key number 19. Here is a guide that we also created for adding a waste line as another option as well called "How To Add a Pool Waste Line"

Can I pay for airfreight rather than wait 2 weeks I want to purchase a Pentair 520 cartridge filter

A  Answered on 12/10/2020 by InyoPools Product Specialist Hector F.

Hi Chris, unfortunately, this filter cannot be expedited as it is shipped via freight. Currently, it has an approximate delivery lead time of 3-6 business days in the continental USA.

I have a crack in the lid assembly. Is there a part number for just the lid assembly and not the entire unit? Thanks in advance!

A  Answered on 3/3/2020 by InyoPools Product Specialist Lennox H.

Hi. The Tank Lid Assy., 520 sqft (Post-11/98) - 178582 will work with your unit.

I know this may get a laugh, however, is it possible to only replace the bottom of my clean and clear unit? it is leaking due to corrosion and do not have $1000 to buy a new unit. Any advice would be appreciated.

A  Answered on 12/13/2019 by InyoPools Product Specialist Kevin G.

Hello,Thank you for contacting Inyo Pools. You can go with THIS part, if your unit was installed after 11/98.

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.

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.

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?
