The guy who is going to do my liner recommended that I have a single loop for all four returns. Go all the way around the pool, with a tee to each return, and a single output from the filter. The exact opposite would seem to be four separate home runs, one for each. In terms of flow, I don't see any benefit one way or the other. The only benefit might be that if there is a leak, finding it may be slightly easier with the four home runs.
Separately, if my wall fittings are all 1.5"...seems like using 2" pipe just to switch to 1.5" at the fitting doesnt make any sense for the home run scenario. Using 2" for the loop, and 1.5" for each tee makes sense, or using 1.5" for four home runs would make sense.
Im leaning towards four, 1.5" home runs, one for each return, and a single 2" from the skimmer to the pump.
