Abstract
A distribution valve of an in-floor pool cleaning system is provided. The distribution valve includes a housing having an inlet port and a plurality of outlet ports. A turbine within the housing rotates about a shaft in response to fluid flowing through the inlet port. The turbine is releasably coupled to a gear mechanism, and the gear mechanism is releasably coupled to a distribution valve disk, the disk having an aperture therein. As the turbine rotates, the gear mechanism also rotates and drives the rotation of the disk around the shaft. The rotation of the disk sequentially places the aperture over one of the plurality of outlet ports, thus allowing fluid to flow out of the outlet port over which the aperture is positioned, but restricting fluid flow into any of the outlet ports that are covered by the disk.
