Hi, first time poster.
I have read every thread I could find and still want to confirm a Pentair Quad 100 is the best decision
I've been in house for a year and have fought the pool.
I installed a pentair vs pump but pool service man strongly suggesting I increase the filter size from hayward pro grid 48 to a pentair 4000 (60). I think mostly because its bigger and he knows the filter and can service it easy. It's only. 20% increase.
I just had a hayward multiport valve put on and new oring (the good one)
If I'm going through expense of switching, everything I read points to 2x pool size, big as possible, etc. i want my pool guys support, but should I push for quad 100. Or should I push for hayward 72 pro grid, since I have the new multi port, etc? Or will the pentair 4000 (60) be the same?
Pool is 42x22 and 9ft deep end. I have two skimmers, one just got opened up at skimmer diverter.
