A reconfigurable water distribution system for a walk-in tub bathing installation including two or more types of discharge ports for discharging water. The system includes a single motorized pump having an input connected to a suction port of the bathing installation, and an output port delivering pressurized water. A pipe system selectively connects the pump to the two or more types of discharge ports to selectively direct the pressurized water to the different ones of the types of discharge ports. The system selectively enables the bathing installation to perform a plurality of different functions using a single pump.

A hot tub vacuum attachment apparatus for cleaning debris from a hot tub utilizing the integrated pump system includes an attachment head to selectively engage a filter housing of a hot tub or pool. A tubular stem has a stem outlet end coupled to, and in fluid communication with, the attachment head. A filter mount is coupled to the tubular stem. The filter mount has an output end coupled to a stem inlet end of the tubular stem, an input end, and a filter receiver coupled between the output end and the input end. A filter system is coupled the filter receiver of the filter mount. All fluid flowing from the input end to the output end passes through the filter system to collect particles and debris. A flexible hose has a hose proximal end coupled to the input end of the filter mount and a hose distal end.

A passive cooling system for an electric motor drive circuit in a bathing installation, including a section of hollow pipe made of a thermally conductive tubing material, the pipe configured to form part of a water recirculation path of the bathing installation. An adapter structure has a conformal surface configured for attachment to an outer surface of the pipe and a circuit contacting surface for attachment to the motor drive circuit, the adapter structure fabricated of a thermally conductive adapter material. The adapter structure provides a thermal conductive path between the motor drive circuit and the pipe section, configured to pass heat generated by the circuitry to the pipe section and into spa water flowing through the water recirculation path, to cool the circuitry and warm the spa water.
