Abstract
A pool, spa, hot tub or the like having a basin capable of retaining water, a first pump for recirculating a portion of the water within the basin to inlet jets within the side walls of the basin and a second pump for recirculating water from the basin to additional inlet jets in the side walls of the basin. Both the first pump and the second pump are driven by a single double-shaft electric motor.
