Update…
PB wants $800 plus 3x$112 (valves) to replumb and would only use ball valves to control flows. So when I get a chance later this spring I’ll start a thread to do it myself if this group of experts wouldn’t mind advising

. I’m handy but only experienced with irrigation pvc….. the biggest headache I see is the lack of extra pipe to cut out…
In the meantime I’m going to get a hose, in-line and vacuum head…..
A few questions please…. (Note the skimmers are pentair Bermuda 2”)
1) PB recommended to put a tennis ball in one skimmer and plug directly into the other - I belatedly realized after reading posts last night I should have insisted they plumb the two skimmers in parallel rather than series. They are not connected to mains but run into a T and then in one line back to pad. (That explains why one skimmer has better performance than the other). I see also a flap at the bottom that can swivel over the hole. Does that flap plug the unused skimmer sufficiently?
2) are skimmer plates needed or can the hose plug directly into skimmer like PB says? I see both answers if I search online … if it can plug would i need an adapter for the skimmer?
3) are hoses universal? Or smaller is better for suction or bigger better for debris etc (in terms of hose diameter l)
4) can anyone recommend a good in-line leaf filter and hose?
5) i found the weighted triangle Hayward head that
@Newdude recommended but not a larger 18” version. I think I am mixing up the recommendations…. For an 11x29 rectangle pool does an extra 6” make a lot of difference in skimming performance?
Many thanks in advance
