Abstract: A valve housing is claimed which provides for diversion of fluid flow into a valve cartridge from a selected inlet through a selected outlet to the valve cartridge. An opening is provided in the housing in which the cartridge is located. The housing also has diverting mechanisms disposed between the cartridge and the fluid inlets. The diverting mechanisms may be adjusted to orient the fluid flow into the valve cartridge. For example, if an installer incorrectly installs the hot and cold water inlets to the housing, the diverting mechanism may be moved to provide the correct orientation of flow into the valve cartridge.
