I've pretty well replaced anything non-functioning on my pool this year and I'm just getting to the two skimmers. I have found the replacement weirs online #08650-0022. I have two questions since mine are long gone. 1. Should I go with the original hinge design and if so can someone tell me how the hinge is attached? It almost looks like their were plastic rivets holding the hinge on. 2. I recall seeing a video somewhere showing a spring loaded replacement weir that just snaps in? IS this a better design or just a gimmick?
