I have an inground liner pool L-shaped apprx 36000 gal. Have contracted to have the coping replaced. It is currently red brick and it will be replaced with red brick. I am also having a new liner installed. I figured this was a good time to switch to SWG system. The pool company I have used for years proposed a Pentair IC-40. Howerver, the contractor doing the coping recommends I use a PoolPilot system. Which of these is better or should I concider another system?
