A valve assembly is provided including a housing having a top and bottom and having disposed between its top and bottom an opening wherein a cartridge is inserted. The housing has axially aligned inlets and outlets for hot and cold water, and carries a cartridge. The cartridge includes portions which are moveable in relation to said housing and a stationary sleeve having a first area and a second area and inlets and outlets, and an interior smooth surface. The cartridge has disposed within the stationary sleeve a moveable stem member which is rotatable and preferably non-reciprocal. The moveable stem member has a perimeter, and has disposed about its perimeter a first and second chamber area separated by a compound seal. The seal includes a first primary sealing portion for sealing the inlet of the stationary sleeve and a secondary seal portion for separating the first and second chamber areas of the moveable stem member. The moveable stem member has disposed therewith inlets for allowing water to pass into the center thereof, wherein there may be contained a pressure balancing spool or a water separating plug. Preferably the outlets of said moveable stem and said stationary sleeve being substantially L-shaped, and inverted L-shaped respectively, which are selectively alignable to provide for an increased volume of water through the valve assembly. The housing includes a dividing dam in the outlet to the bathtub, for example a bifurcated cross section, wherein when water enters the valve assembly the first and second chamber area of the moveable stem member will maintain separation of the waterways for the first chamber area for cold water and the second chamber area for the hot water, and wherein the first and second chamber areas of the stationary sleeve will provide the necessary waterways for water exiting the valve. The first waterway area of the stationary sleeve being in alignment with the outlet from said stationary sleeve to provide in combination with the interior of said housing opening a waterway and mixing chamber to provide a path for mixed cold and hot water to -2- exit through the tub outlet. When a diverting plug type mechanism is operated typically found on the spout outlet of a tub, the water exiting the spout will be diverted back and over the dividing dam into the second cross sectional area of the bifurcated outlet back into the second waterway area of the stationary sleeve, such waterway area provided thereby between the sleeve and the housing, will divert the water up to the shower outlet.
