I can't help you find a weir, but just wanted to say that it is OK if you don't have a weir. I don't. Mine broke several years ago and I just don't worry about it. The only thing is that when the pump shuts off and the suction is gone, any debris in the skimmer will float back out into the pool. My solution for that is to just dump the skimmer basket before shutting off the pump. Maybe somebody can suggest someplace to buy a replacement, but if you can't find one, don't sweat it.

Hope you enjoy being a part of our forum!

EDIT: By the way, it is usually best to start your own thread instead of tacking onto the end of somebody else's thread, especially if it is a really old one like this one is. Just an FYI.
