I've just purchased a new Intex pump (upgrading the 2650 GPH sand filter) and a Hayward skimmer. I figure if I'm going through the upgrade process, I should get rid of those restrictive Intex plunger valves, but since I'm doing THAT upgrade ... well, I'm just going to hard-plumb the pool and do this right!
I do have a question though. I've seen several hard-plumbed installs and while all of them look good, there seem to be two schools of thought. One one hand you have people like jsf0656 who have a single inlet (skimmer) and send the output from the filter to both of the old "returns" and into the pool. You also have the other side with people like Verdog who have one of the "returns" and the skimmer going to the inlet and the output from the pump going only to a single "return" and back to the the pool.
Why were these setups done this way? Is one better than the other?
