How to Fix a Shower Diverter Valve
Three-handle bath faucets have one handle for hot water, a second for cold water, and a third to control the diverter valve. This valve directs water either to a bathtub spout or shower head, and can become worn with use. If water flow is weak, or the valve sticks, or if water leaks out of the tub spout when it is supposed to be diverted to the showerhead, the diverter valve must be fixed. Does this Spark an idea?

Tips & Warnings
If the diverter valve is a cartridge type, it should be replaced with a new valve, not taken apart and cleaned.
Turn off water to the valve and drain the line before beginning work.
Carefully seat all threaded parts before tightening to prevent cross-threading.
