I have debris reentering the pool after the pump shuts off and I would like to add a skimmer weir. There are no visible holes though. There is a piece where the weir would attach that fits down into 3 slots with a screw holding it in place. It doesn't appear to be broken like the door broke off, it has a clean edge.
Is it possible that this piece would be removed and a weir would slide down into those slots? The only ones I can find require holes.
