    DE filter and SWG - any issue

    I am relocating and the new house has a nice pool with DE filter and tablet feeder and heater. I want to convert to SWG as that is what I had/have in my other home now.
    Is there anything special I need to know about using the DE filter and this? My other pool was cartridge filters. The builder here quoted $2K for turnkey conversion which seems ridiculously high for adding an SWG so I suspect he plans to do more and wondered what it might be....hasn't explained it yet.
    thanks

    Re: DE filter and SWG - any issue

    Some older DE filters were Stainless rather than plastic - is that involved here or is this a fairly modern DE filter?

    I don't know of anything that is incompatible between the DE filter and the SWG.

    Current setup
    1) 1.5 HP Whisperflow Pool Pump

    2) 48 FNS+ D.E. Pentair Filter

    3) Rainbow 300 Chlorinator

    4) heater, LP I believe

    5) pop-up pool valets

    I presume the $2K turnkey involves more than just the cell generator....what, I'm not sure. What in the world would that be? I 'm used to the Jandy....

    As UWV said, no problems using DE with a swg. An appropriate sized swg (like the jandy apure1400) would run you ~$900 bucks online, so it seems the pb is charging about $1000 for the install. I would ask for details.

    One issue to keep in mind. As you backwash your filter, you're dumping out salt, so it must be replaced to maintain correct salt levels.
