Hello, I have a Hayward SP1580 1hp pump. I currently have an old Doughboy sand filter. * am looking for a new cartridge filter. I see setups with the filter and pump on a common plaform with quick disconnects. Is there a specific Hayward cartridge filter that I can buy with a platform and fittings that would work with my pump if I rotate the outlet. In other words, I would like to buy the filter/pump platform kit without the pump. Is this possible?
