A water distribution valve assembly is carried in a multi-port water distribution valve with a bottom inlet. The assembly includes a bearing plate including a plurality of openings, and a valve plate including a port, the valve plate mounted for rotation on and with respect to the bearing plate. A drive assembly is operably coupled to impart rotational movement of the valve plate with respect to the bearing plate, in response to the application of a flow of water, through a plurality of positions each characterized by the port of the valve plate being aligned with a respective one of the plurality of openings.

A water distribution valve for directing a flow of fluid through a swimming pool cleaning system includes a housing having an inlet and outlets. A plurality of gates are mounted in the housing, each corresponding to a respective one of the outlets. Each gate is mounted to open and close the respective one of the outlets to which the gate corresponds in response to the flow of fluid into the housing from the inlet.

A wearless water distribution valve directs a flow of water through a swimming pool cleaning system and includes a housing having an inlet, outlets, and an inner surface bounding and defining an interior coupled in fluid communication with the inlet and the outlets. The valve further includes a disc having a port, and being mounted for rotation in the housing for movement among a plurality of positions, each position of the disc characterized by the port being aligned with a respective one of the outlets. The valve further includes a drive assembly carried by the housing and operably coupled to impart rotation to the disc. In response to application of the flow of water into the housing, actuation of the drive assembly imparts rotation to the disc through the plurality of positions. The disc is disposed in spaced relation away from the inner surface of the housing.
