I have included a couple pictures in case someone knows what make/model it may be. So as the title states, my skimmer doesn't have a weir. I've read a few threads on TFP regarding this issue, but the answers all seemed to be the same. Measure and order. The thing is, my skimmer opening doesn't have any holes for pins or anything to keep the weir in place and allow it to rotate. The skimmer housing on the bottom is angled up slightly as the water enters the basket area. However my 'pull' or 'suction' coming from the skimmer isn't very strong, and it seems to only collect surface debris if it is within a few inches in from of the skimmer. I'm thinking a weir might be my problem. Even if it isn't, I'll be needing a weir as I bought a timer for my pump this year and won't be running it 24/7 like last summer. Any ideas or directions you can send me in would be appreciated. Thanks!
(edit - The ID of the skimmer measures 13.5" x 5.25")
(ps. I know the skimmer is nasty. I'd replace it if I could with ease...Sort of inherited a baqua pool late last summer and doing what I can to fix it)
