Hello I have a 18x36 vinyl liner pool. We are getting a new liner tomorrow. My thought is to get a SWG in the next couple of weeks to cut down on the maintenance. I am leaning towards either the Hayward Aqua Rite 15 or the Pentair IC40. What are the pro's and cons. The IC40 appears to be a little more forgiving for plumbing space. I am limited for space and will install the SWG where my Hayward Chlorine feeder is located today. I only have around 20" of a straight pipe run to work with. There is a 90 on one end coming down from the sand filter and I have a 90 on the other end that turns down into my slab headed out to the returns. Is there a big quality difference between the two. I plan to buy off the internet and install myself. I am open to other options if they make more sense. Thanks in advance!!
