Skimmer weir not rising

[consoleman]

You see that the thing....I cant see the foam on the weir. Maybe its internal

Really? Usually one side is plastic and the other is styrofoam, that floats it. If they are both plastic it is probably the smoother side that faces the pool, with an angle. Go to some on line pool sellers and search for "weir" and look at them.

I have weirs that are all plastic and sealed. Presumably the air inside provides the floatation. Could be this type and filled with water. They are generally available for replacement through a pool supply house.

Good suggestion! Weirs aren't too expensive and replacing it with one the proper size cannot hurt. I've replaced mine at least once.

Skimmer weirs, at least the Sta-Rite/Pentair (U-3) have, in the past 5+ or so years, have become increasingly thin. I assume, like you said, that they are a pocket of air as opposed to the "tried and true" Styrofoam. If the weir floats when the pump is off, then it is probably ok. It should hover between the floor of the throat and the waters surface. You can try adjusting the water level in the pool to increase/decrease that amount of water in the throat that the weir has to deal with. If you decide to get an aftermarket weir, it will have Styrofoam, and perhaps perform better for you.
