Hey everyone, here's my set up and my lengthy question:
30,000 true "L" vinyl, 2 skimmers, nearly 4 feet from each other on the 90 degree turn. 3ft to 8ft depth with 1 main drain
Only had the pool a year (bought house last year june), noticed that I can't seem to run the skimmers and main drain at same time. At my return valve (has a handle with arrow with words "closed", and numbers: 1,2,3,inlet), I have 2 pipes; one comes up and down into valve, other from bottom then one pipe from valve to my pump.
I've been using only main drain while opening the pool cause water level is below skimmers (another issue i'll get to later). To use main drain I have the handle pointing to #1. #2 seems to operate only skimmers, #3 seems to runs skimmers but no main drain as well (I know cause while water is low it'll suck all the water and lose prime). Last year I remember trying all settings, swimming down and noticing that only #1 would operate main drain. None of the others would seem to make the drain pull any suction at least to the touch.
If it matters I have 2 holes in each skimmer. the holes in each furthest from pool were plugged, in the process of attempting to take them out i broke off one of them causing me to seal it by other means that works for now. From what I could see through the plug was rock that looked like back fill and no pipe or any evidence of one. I've been told that the pipe could be broken off or it didn't go anywhere.
Sorry to be so lengthy but my question still stands, how can I run both my skimmers (or at least one) and my main drain.
Pump is a 1.5 hp magnetek, no leaks detected other than a few air bubbles in pump strainer and bubbles out of few jets. I have 6 jets and 1 near skimmers that I use for polaris. The jets push decent pressure but obviously decrease when filter is clogged. So from what I can tell the pump is running well. Hold around 15 psi at filter when not full of ****.
Any help on this would be appreciated. If it helps last year with only skimmers the pool was rather clear but always collected cloudiness and debris in deep end.
