I moved into a foreclosure home that had a pool (thankfully it was clean) and unfortunately, I have no schematics, diagrams, or manuals on how to run it. I know I have a Hayward 1HP pump that works good, a Hayward sand filter that seems to still be working, and I have a skimmer that has a basket, and three holes on the bottom. Two of them are below the skimmer basket so that seems to be normal from what I've learned thus far. One goes to the pump (that has no diverter valve for the main drain) the other I think goes to a hole that's about a foot below the skimmers main opening, and a third hole just off to the side and below the basket, that I think connects to the drain. I have not been able to find out what model I have to find parts I need. I don't have any valves, diverters, balls, flaps, attachments, or anything other then the leaf basket in, or around my skimmer. The only identifying information I can see is a broken, sun beaten cover with the American Products logo.
I have found out that my pump/filter has one input and the output branches off to 3 lines and each one has it's own gate valve. One for a single return to the pool and what i guess is an aerator that has a broken adjuster/regulator above it in the tile above the waterline (small bubbles coming out of it with the water), another output line going to a few more returns in various parts of the pool, and the 3rd smaller line going to a cute little thing that sprays water into the air.
aside from a couple very small leaks in the PVC pipe, I don't think there's anything wrong on the pump end of things, it's the parts I might need around the skimmer that I'm lost on. Parts that I don't even know what I need to look for, and can't find a model to match.
p.s. Thanks in advance for your time to reply.
