A three-handle faucet type has two handles to control hot and cold water, and a third handle to control the diverter valve and direct water to either a tub spout or a shower head. The separate hot and cold handles indicate cartridge or compression faucet designs.
If a diverter valve sticks, if water fl ow is weak, or if water runs out of the tub spout when the flow is directed to the showerhead, the diverter needs to be repaired or replaced. Most diverter valves are similar to either compression or cartridge faucet valves. Compression-type diverters can be repaired, but cartridge types should be replaced.
Remember to turn off the water before beginning work.

How to Repair a Compression Diverter Valve
Step1: Remove the diverter valve handle with a screwdriver. Unscrew or pry off the escutcheon.
Step2: Remove bonnet nut with an adjustable wrench or channel-type pliers.
Step3: Unscrew the stem assembly, using a deep-set ratchet wrench. If necessary, chip away any mortar surrounding the bonnet nut.
Step4: Remove brass stem screw. Replace stem washer with an exact duplicate. If stem screw is worn, replace it.
