ABSTRACT:
A diverter valve assembly includes a valve body rotatably mounted in a cavity of a housing. The housing has an inlet connected to a water supply, a tub spout outlet, and a showerhead outlet. The showerhead outlet is connected to a showerhead via a riser. The valve body has a jet orifice in communication with the inlet and alignable with one of the outlets. The valve body also has a flange which rotatably seats an elastomeric sleeve. The sleeve, when the jet orifice is aligned with an outlet, is aligned with the other outlet. The sleeve and flange form a pressure chamber which is in communication with the inlet. When the sleeve is aligned over the tub spout outlet, and the water supply is turned on, the back pressure caused by the showerhead flexes the sleeve to seal the tub spout orifice. When the water supply is turned off, the elastomeric sleeve relaxes to allow water to drain from the riser to the tub spout without the valve assembly changing position.
