    Sand Filter Addition to an Intex SWG

    I currently have an Intex SWG that came with a cartridge filter. It's one of those all in one filter, pump, chlorinator types. I would like to replace the cartridge filter with a sand filter. Has anyone done this and can share the procedure for doing this? Is this possible or do I need to buy a new sand filter/pump combo? Any help would be greatly appreciated.

    I may be possible depending on the unit you have. Post a pic of it and maybe we can tell you what's needed.

    Intex makes a sand filter and some have converted to Hayward and other brands.

    A photo will make suggestions much better.

    This is the intex pump/filter combo that I have. I basically want to replace that cartridge filter on the right with a sand type. Much lower maintenance as I understand it. The pump unit I have is rated at about 2500 GPH.

    The pump is rated for 2,000 gph. If there's a way to disconnect the filter from the pump you should be able to connect it to a sand filter and then connect the sand filter to the flow switch where the 90º ell is and it should work fine.

    Yes I believe there is a way to do this. I'll look at it once I get home.

    Also I understand that the sand filter/pump units have an automated backwash cycle. Is this an automated function of the filter unit that will work the same if I simply attach it to my pump?

    Btw, if you can recommend a relatively inexpensive one rated for the pump capacity, it would be greatly appreciated.

    Thanks also for the quick replies......

    I have never heard of an automated backwash on an Intex filter unless your name is Otto Mated (joke). i could be wrong.

    Can you post the model number and brand details on the sand filter?

    Not sure, my cousin's pool came with one and I thought he mentioned that it did. He could have been wrong also. I'll see if I can find out more from him.

    Thanks

    Turns out I was wrong about the Otto Mated backwash. It is manually done every so often when the rate starts dropping. Still 100 times better then cleaning a cartridge filter.

    We recommend backwashing when the pressure rises 20-25% over the clean pressure. Waiting for a discernable drop in water flow is usually much too long.
