A skimmer assembly adapted to be connected to a water circulation system to remove floating debris from the surface of a swimming pool or other body of liquid is provided with a floatable shut-off weir pivotally mounted in the inlet passage of a skimmer tank. The weir is responsive to the water level in the skimmer tank and serves the dual purpose of maintaining a constant water level in the tank when the water level in the pool is normal, and automatically seating against an appropriate seat to close the tank to prevent air inclusion into the water circulation system when the pool level drops below a predetermined point.
