I have a 16' x 32' inground pool. Shallow end is roughly 3.5 feet and deep end is 9 ft deep. 1) Would this be the right filter? 2) Does this use the Vari-Flo valve? 3) How much are replacement cartridges and how often do they need to be replaced?

A  Answered on 5/17/2012 by InyoPools Product Specialist Patrick P.

Yes this would be a great choice of filter for your sized pool. This particular filter does not use a backwash valve like the vari-flo valve, typically a backwash valve is used on a D.E filter or a sand filter and not on a cartridge filter. The generic replacement cartridges for this filter are roughly $50 each and 4 are required, 4 cartridges are included with the purchase of this filter. Typically the cartridges will last roughly 3 years before needing to be replaced.

What size filter do I need for a 30000 gallon 20 by 40 pool.

A  Answered on 5/11/2015 by InyoPools Product Specialist Lennox H.

George, This Hayward Swimclear Cartridge 425 Sq Ft Filter can handle a maximum flow rate of 150 GPM. So if your pump does not exceed that amount then this filter will be great for your size pool.
