I am replacing a 24" sand filter operating from a Hayward 1HP Super Pump. My pool is an in-ground that holds 35000 gallons. Will the C1200 filter (1.5" pipe) be adequate for this pool which is lightly used?

A  Answered on 4/23/2013 by InyoPools Product Specialist Patrick P.

Yes this would be a proper fit for your pool. The Hayward Super Pump (1HP) would not be able to exceed the flow capacity of the C1200 allowing it to be a proper and safe fit for your system.

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.

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.

Hello, I am considering the C1200 filter for my above ground 24' dia. pool. Will this filter cover the needed GPM and maximum gallons of approximately 22,000 gallons? I have a 1.5 HP pump as well.

A  Answered on 10/20/2014 by InyoPools Product Specialist Brian M.

The C1200 filter will handle 120 gpm on a residential pool and will turn over 57,600 gallons in 8 hours. It will be more than plenty for your pool.
