So skimmers work, suction is really good when I turn down/off main drain, but pool surface is still full of stuff. Weir doors stay open and don't seem to close or lift even a little. They move freely as I can push them up and there is no restriction. Also I know the suction works great as it almost ate my hand off when feeling for suction. When I crank rpm up to 3000 flow improves but still debris tends to float by. Water is midway, maybe slightly higher up the door and if I hold the door close skimmer drains very quickly.
