There are universal weirs (the door) that are spring loaded. If you measure your skimmer you should find a match.Here is a link to some available. There are also skimmer baskets that have a floating weir. Look at your skimmer basket and see if there is an embossed number on it. That can help us to determine if it is missing the weir. Here is a link to a common and older skimmer basket that was made with a weir that floats inside it: here is the weir that goes inside it this is a commercial pool and needs the weir for inspection, and it has not had one before, maybe it is "grandfathered" . Please let me know if I can help further.

how does a weir work, what is it supposed to do?

Expert:  Poolservice123 replied 2 years ago.
The weir door assists the skimmer in removing debris from the top of the water by increasing the movement towards the skimmer. It also will prevent air surges into the pump system when the pool is agitated (people in it). When you turn the pump off it will prevent the already collected debris from floating out of the skimmer.
