We've had a Jandy Aquapure EI for 3 years and the control unit died in year 2 (fixed under warranty) and again in year 3. Entering year 4 it's time to cut my losses and replace it with something reliable. I have an above ground pool installed partially below ground. I'm a little confused as to the difference between above ground and below ground SWG. I'd like to get a Hayward Aqua Right as it seems to get good reviews and is reliable. Will that work or do I need to hunt down an AG SWG? Thanks for any feedback.
