The lower end of the chamber has an opening for dumping water from the chamber. A valve is provided for blocking the opening by the water pressure of the pool and a filter is provided for filtering debris from the water before being dumped through the opening. An ambient air intake tube is connected to the upper end of the chamber and has an opening whereby ambient air can be trapped in the chamber by the operator.
