How to Fix Shower Diverter

A shower diverter is a device that changes the water path from the bathtub faucet to the showerhead. Most shower diverters work by a knob or pin, located in the center of the two hot and cold knobs. 

Most diverters have three valves known as tub diverter valves. Other than valve diverter showers, the showers which have detachable or handheld heads have built-in diverters.

After triggering the shower diverter, if water continues to leak from the shower faucet instead of the showerhead, the diverter is broken. The reason for that is a busted rubber seal, or another part of the shower diverter is blocked.
