    Swg for 25500g

    Hi all,

    what swg would you recommend for a 25500 gallon in ground pool? PB likes pent air but reviews look suspect on some sites? He's coming tonight to finalize details. Thanks

    There are many satisfied people at TFP with Pentair SWG's. If your pool has Pentair automation then it will be a perfect fit for the system. If you don't have automation then the Pentair SWG's can be a little difficult to dial in the output needed to make the right amount of chlorine since it can only be adjusted by 20% increments.

    Whatever brand of SWG you decide on make sure it is rated between 40,000 to 60,000 gallons.

    If you are not going to have an automation system, I would suggest the AquaRite T-15 (Hayward). It has the output you need for that size pool and you can set the output control in increments of one percent, which is not true of the Pentair. I have one and the T-15 cell lasted 7+ years, making my chlorine cost about $57 per year. The only problems I ever hear of are a resistor that can fail. The part cot $2.50 to replace and takes about a half hour. Mine had to be fixed after ten years of service.

    Your pool builder may be using all Pentair equipment. Many builders have a discount arrangement with one manufacturer. My PB used all Hayward, I have since changed out some equip. So I pick and chose. Pentair pump and solar control, Hayward SWG, etc.
