I have 32x14 fiberglass inground insert that holds approximately 16000 gallons. I’m currently running a Hayward 2.70 VS pump with a Hayward DE3620 filter. I’m considering changing my filter because I’m tired of cleaning filter grids and dealing with DE. My local pool store advises to use a Hayward sand filter with glass media. I’m not a fan of sand filters due to the waste of backwashing. I’m thinking of use a cartridge filter. What would your recommendation be?

A  Answered on 10/13/2021 by InyoPools Product Specialist Megan C.

The Hayward Swimclear Cart. Filter 325 sqft - W3C3030 https://www.inyopools.com/Products/02201212000434.htm or the Crystal Water 325 sqft Pool Cartridge Filter - 570-0325-07 https://www.inyopools.com/Products/07203367087343.htm would be great replacement options to the Hayward Pro Grid DE Filter 36 Sq Ft w/o Valve - W3DE3620

Hi! I want to know what is the difference between MODEL # W3C12002 and Model # C12002 , please.

A  Answered on 5/2/2021 by InyoPools Product Specialist Patrick P.

Hi Ruben, The W3C12002 and Model # C12002 are the exact same filter. The W3C12002 is the model # that is allowed to be sold on the Internet. If you purchase the W3C12002 on the Internet then it will come with the full manufacturer warranty and if you purchase the C12002 on the internet then it does not come with a manufacturers warranty.

  • Commented on 5/7/2021 by Product Owner

    Why would there be to models exactly the same, one with warranty and one without? Is the C12002 sold and warrantied by pool builders/installers? Trying to understand why there would be two models for the same unit?

    • Commented on 5/8/2021 by InyoPools Product Specialist Patrick P.

      Hi Mike, Yes the C12002 is sold by pool builders and brick and mortar retailers where the W3C12002 is the internet version, however the model is the exact same thing. Hayward set up this model to only allow for there product to be sold by Authorized Online Sellers which Inyo is one of, so if you purchase this filter from us you will get the full warranty.

I can never get the top part of the housing to screw on flush and even witout a struggle, and now with new o-ring its impossible and it leaks and sits nowhere flush. is it warped and old? any recommendations? C12002 ID 21120607004274006

A  Answered on 8/9/2019 by InyoPools Product Specialist Joe S.

Hi Johnny, it sounds like the tie rod may be cross-threaded. We would recommend replacing the complete unit to an easier one to service. Such as the Hayward SwimClear C150S Single Element Filter.

?     Asked on 6/3/2019by Buddy

How long should a filter chamber last, C1200?

A  Answered on 6/3/2019 by InyoPools Product Specialist Patrick P.

Hi Buddy, Normally around 12 months for the filter cartridge. The filter tank should last 20+ years.

?     Asked on 11/19/2018by Inyo Visitor

A  Answered on 11/19/2018 by InyoPools Product Specialist Hector F.

Yes, any new complete filter purchases do come with the cartridges. 

?     Asked on 5/30/2018by Gustavo

I have had an old Hayward C1100 filter for 20 years that I need to replace. I have a pentair inteliflow variable speed pump in a 20k gallon pool. Would you please recommend a replacement cartridge filter? Will the c12002 be appropriate? Do you have any coupons for today?

A  Answered on 5/30/2018 by InyoPools Product Specialist Lennox H.

Hi, Gustavo. The C12002 will be a step up from the old C1100 cartridge system. The C17502 model will be an even better replacement option. 

?     Asked on 3/5/2018by Glenn

I currently have a Pentair CC150 Clean and Clear which is broken. The pool is 15K and I have a Pentair Intelliflow pump. Can I replace my broken filter with a Hayward C1202 even though I would be going from a 150 to a 120?

A  Answered on 3/5/2018 by InyoPools Product Specialist Kevin G.

Hello, we do not recommend going down on filter size due to the fact that you can risk damaging your filter from increased pressure in your system.

Have existing Sta-Rite PXC 125 Cartridge Filter, which is no longer available. Would this be a good replacement? Pump is 1.5 HP.

A  Answered on 11/13/2017 by InyoPools Product Specialist Lennox H.

Hi, David. This Hayward Star Clear Plus 120 - C12002  can be used to replace your Sta-Rite PXC 125 Cartridge Filter. 

?     Asked on 8/9/2017by Pat

I have a Hayward Star Clear Plus C12002S. Purchased in 2011. Since last year, I have not been able to use a "cleaned" filter - it must be new before it will activate (run) the Zodiac sweep. Have installed a new filter, but sweep will Not work. Do I need a new filter system??? If so, is there one larger than the C12002S?

A  Answered on 9/22/2017 by InyoPools Product Specialist Alex V.

Pat, I would recommend having the cleaner checked. Depending on the model, a jet or gear may be causing the issue. As for the filter, the next sizes up would be the C17502 (175 sq ft) and the C2002 (200 sq ft).

I have a 12,000 gallon pool with a 1 hp pump, currently has a sand filter. We are looking to change to a cartridge filter. What do you recommend?

A  Answered on 6/28/2017 by InyoPools Product Specialist Patrick P.

Hi Jdt, This Hayward C12002 would be the cartridge filter I suggest for your size pool.

?     Asked on 4/22/2017by Frank

I have a 10000 gal in ground pool with a 1 1/2 hp pump I need to replace the current DE pool filter Sta-rite PLDE-48.Is the Star Clear Plus 120 Sq ft filter a proper replacement for my pool? where are the 2" input/output ports located on the filter?

A  Answered on 4/24/2017 by InyoPools Product Specialist Lennox H.

Hi, Frank. I would recommend the C2002 or the C200S because these options will provide a better flow rate and longer cartridge life span than the C12002.

?     Asked on 3/8/2017by John

I have a 15,000 in ground pool with a Hayward Tristar SP3210x15 1.5 hp pump. Can I use the c1200 and use a reducer from 2" pipe to 1.5" into the filter? i didn't know if the small reduction into the filter would cause a problem. Thank you!

A  Answered on 3/8/2017 by InyoPools Product Specialist Lennox H.

Hi, John. to confirm if this filter is suitable for your pool we will need to know the flow rate of the pump. You can calculate the flow rate of your pump by following the steps in how How To: Size a Pool Pump guide.

I have an 22000gal pool with a Pentair 3hp variable speed pump, and am replacing an old Sta-Rite 100gpm filter system. Do the C1200 and C12002 seem like good replacements? What is the difference between the two.

A  Answered on 2/3/2017 by InyoPools Product Specialist Alan M.

Either one of these would be a great option to replace your current filter. The difference between the two is the C1200 has 1.5" intake and output ports, while the c12002 has 2" intake and output ports.

?     Asked on 9/19/2016by scott

My pool is almost 10,000 gallons, I'm replacing the pump with a VS pump and a new cartridge filter and space is not a problem. The Hayward C1202 is probably everything I need but what is the difference between the Hayward C150S and C17502 other then they look different. And if I decided to go with a quad filter which one would you recommend. It doesn't have to be a Hayward brand. thanks

A  Answered on 9/19/2016 by InyoPools Product Specialist Scott W.

Really the only difference between the two as far as functionality is the plumbing is going to be a little different. With a quad filter, part number C3030 would be a great you for your pool as well.

I have an old Pentair 36 sq/ft fns DE filter and would like to replace it with a cartridge filter. Can you give me a couple options to replace it with? Thanks

A  Answered on 7/13/2016 by InyoPools Product Specialist Lennox H.

Hi Jason, Switch from a DE to a cartridge unit I will recommend going to quad cartridge filter versus a single cartridge filter. The Pentair CCP320 or Hayward SwimClear C3030 are the recommended models.

?     Asked on 10/1/2014by Guest

Are there specs on how many microns this filter is rated at? Is there available another filter that won't allow finer particles to pass through?

A  Answered on 10/1/2014 by InyoPools Product Specialist Patrick P.

As a rule, sand filters sift particles ranging from 20 to 40 microns in size.  Cartridge filters can sift particles as small as 10 to 20 microns in size.  DE filters can sift contaminants as small as 1 to 3 microns in size. This makes DE filtration at least five to six times more efficient than sand filtration systems.

?     Asked on 10/1/2014by Guest

Is the C12002 and the C12002S the same?

A  Answered on 10/1/2014 by InyoPools Product Specialist Patrick P.

The C12002 has threaded ports and the C12002S has slip ports. Most people prefer the threaded ports of the C12002.

?     Asked on 9/16/2014by Guest

The filter I had before needed to be backwashed. How do I backwash this Hayward C1200 or C12002?

A  Answered on 9/16/2014 by InyoPools Product Specialist Patrick P.

This filter model type is a cartridge filter and does not actually need to be "backwashed". The filter cartridge element inside must removed on a regular basis which is on average about every month, rinsed down with a water hose and pressure nozzle of some sort and then put back into place.

?     Asked on 9/21/2006by Guest

Does this come with the filter cartridge and gauges?

A  Answered on 9/21/2006 by InyoPools Product Specialist Patrick P.

This filter comes direct from the manufacturer and includes the cartridge and gauges.
