I am currently looking at purchasing the Aquasol solar panels for my 18x36 IG vinyl pool that will be installed any day now. My pump will be a WFDS-4 Whisperflo. All of my plumbing will be 2".
My question is should I go with 2" headers on the panels or 1.5"?
I will put these panels on a ground rack so the top of the panels will only be about 5-10 above pool level/pump. Which size would work better with my pump?
