When installing a through the wall skimmer should you have two suction side returns to the pump and one for pushing water back into the pool? I notice the instrux say to do it that way but I also think I see from some pics here that some of you have one for each. Any advantages or drawbacks for each way? We have upgraded our pump to a Hayward Power Flow Max with a 150 sq/ft filter and are finally installing a skimmer. So should I leave the other suction side return and plumb it into the skimmer plumbing or would it be better to just put the skimmer where that one is and have one of each. Thank you.
