A valve assembly is provided including a housing having an opening wherein a cartridge is inserted. The housing has axially aligned inlets and outlets for hot and cold water. The cartridge includes a stationary sleeve containing a rotatable stem member. The stem member carries a compound seal having a first primary sealing portion for sealing the inlet of the stationary sleeve and a secondary seal portion for separating first and second chamber areas of the stem member. Preferably the outlets of said moveable stem and said stationary sleeve are 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 splitting the outlet in two. When a diverting mechanism typically found on the spout outlet of a tub is operated, the water entering the spout will be diverted back into a second waterway area of the stationary sleeve provided between the sleeve and the housing, passing the water up to the shower outlet.
