Looking for some suggestions on pipe size for my new pool (20x40, 25,000gal, 2 skimmers, 4 returns, jr slide, 4 deck jets)(ecostar pump, c4030 filter, h250 heater). The pad is going to be pretty much level with the pool. Farthest skimmer is 60ft away from pad.

My plan at the moment is to run 2" line from both skimmers to the pad then tee into 3" and to the pump. The whole pad will be done in 2". All returns will be 2", slide 1.5", and deck jets 1".

Maybe im over thinking this but im wondering if i should do 3" from both skimmers to the pump and do the pad all in 2.5". I guess im wondering if that would be just over kill and wasting money??

Any input would be great, Thanks in advance!!!
