Abstract
An apparatus for circulating water in a swimming pool including a strainer that is connected to a swimming pool unfiltered intake with a pump connected to the strainer for pumping water from the strainer to a filter. The filter in turn is connected to the swimming pool filtered return for depositing the filtered water into the swimming pool. The invention includes a valve connected to the pump strainer and filter for temporarily altering a flow of water from the swimming pool unfiltered intake or the filtered return to the pump and back through the strainer in a manner to provide a flow of water across the surface of the strainer to remove debris contained upon the strainer surface. A method for cleaning the residue collected by a strainer in a swimming pool water circulation system is also included that includes altering the flow of water from a swimming pool unfiltered intake to a pump and through the strainer in a manner to remove particles collected on the surface of the strainer. The altered flow of water containing the particles from the strainer is then directed to waste.
