Recirculating pet fountain

Abstract

A recirculating pet fountain that includes a basin defining a lower drinking bowl, pump and discharge where water pumped out the discharge is delivered to an upper drinking bowl that conveys the water to either an overflow tube and/or a bridge toward water in the lower drinking bowl including into the tube. The bridge can include a channel and be configured so at least some discharged water clings to its underside via surface tension as water flows toward the basin. The tube has a mouth which can receive water from the bridge that can be free falling water that overflows from the tube into the basin. The tube can include one or more discharge ports that can include flow directors that help direct flow of water received in the tube that overflows out the ports. The tube can be length extensible and can include a flow adjuster that can increase effective tube length and can block one or more ports.
