Do you sell 1 1/2" unions for this filter?

A  Answered on 6/25/2023 by InyoPools Product Specialist Hector F.

Hello Jeffrey, unfortunately Hayward does not sell 1.5 inch unions for this series filter however you can use the 2 inch version being part number 5112-200 and then use the reducer bushing part number 7153-0 to make them plumb to 1.5 inch plumbing.

I'm looking to replace an American Products Quantum CM. What do you recommend?


A  Answered on 2/8/2021 by InyoPools Product Specialist Hector F.

Hi Eugene, the Hayward Swimclear cartridge filter series would be a good replacement series for the Quantum CM series however you will need to get the specific filter model of yours to match or even exceed filter capacity. I do not see any model labels legible however you can also get the part or model number off of the cartridge themselves to confirm your specific filter model.

    Thanks, The pool is approx 16,000 gallons, but I replaced the pump motor last year with an A.O. Smith V-green (2.7 hp). So I have a degree of freedom around the actual filters. Gene

    • Commented on 2/9/2021 by InyoPools Product Specialist Hector F.

      Hi Eugene, understood. Without your current filter model and with free reign essentially you will need to size a new filter. Here is a guide that we put together called "How To Size a Pool Filter" that will assist in calculating that.

Does the Hayward c5030 require DE after cleaning it?

A  Answered on 7/16/2019 by InyoPools Product Specialist Hector F.

No, this filter model does not need D.E. powder. This model just requires the cartridges to be regularly hosed down.

Is the C5030 the same thing as the C5025? I'm looking for a generic cartridge and your website says it will fit a C5025 and nothing shows for a C5030.

A  Answered on 9/25/2018 by InyoPools Product Specialist Lennox H.

Hi, Paul. The C5030 is the current model that replaced the C5025; however, the replacement cartridges are the same PL0106.

A  Answered on 6/3/2018 by InyoPools Product Specialist Lennox H.

Hi, Steve. This Swimclear Cartridge Filter - C5030 does not require a valve. 

?     Asked on 5/26/2018by tom

Does the c5030 filter price on website quoted include the 4 filters?

A  Answered on 5/26/2018 by InyoPools Product Specialist Patrick P.

Hi Tom, Yes the 4 cartridges are included.

?     Asked on 5/20/2018by Tom

I have a 18 x 36 x 4.7 avg depth rectangular pool~ 22.8K gallons. I have 2 skimmers..baskets are 29' & 68' from pump. Currently running a 11 yr old sand filter I want to replace, with a 6 year old STAR RITE MAX E PRO 3.0 HP/3.45 SU HP pump. Previous owner over pumped system when replaced pump because it has 4 water returns in pool & 3 water outlets above. What size filter do you recommend with this pool & pump? If I decided to re-pump, what combo filter and pump?

A  Answered on 5/23/2018 by InyoPools Product Specialist Patrick P.

Hi Tom, In regards to the filter bigger is always better and with a 3 HP pump the Hayward C5030 would be what we suggest. If you did decide to swap out the pump then you probably could get by with the 2 HP Max E Pro Pump or a 2 HP PureLine Prime Pump. The PureLine Prime would require a little bit of re-plumbing. We would still suggest the large C5030 filter even you changed out your pump.

?     Asked on 3/14/2018by Tim

Is the C5030 a direct replacement for the C5520? By that I mean, can I simply unscrew the locknuts on the C5520 and connect the C5030? Also, does the new filter include cartridges? Thanks.

A  Answered on 3/15/2018 by InyoPools Product Specialist Lennox H.

Hi, Tim. Yes, the Swimclear Cartridge Filter - C5030 will directly replace the C5520 model filter. The filter body is the same for both models. The cartridges are included with this complete unit.

What is the distance from your pump to your skimmer so I can calculate the estimated flow rate.

I have a 10,500 gallon in ground play pool that includes 500 gallon spa over flowing into the pool. What size cartridge filter would you recommend to replace my DE 20 year old filter. My pool pump is a 2 hp challenger brand pump.

A  Answered on 2/1/2017 by InyoPools Product Specialist Scott W.

I need to know the distance in feet from the pump to the pool's skimmer(s) so I can calculate the flow rate. This will let me know what size filter you need based on the flow rate.

Old filter had a crack in the side wall approximately 18 years-old.

Written on 11/9/2018 by Guest

After removing the old filter, everything lined up well on the new filter. The pipe fittings were all the same size, so it amounted to an easy fix. No plumber or pool service technician required.
