There are two types of shower diverter valves. One enables your tub to double as a shower, eliminating the need for a separate shower stall. The second type of shower diverter valve is found near the shower head. It enables you to use the standard overhead shower, as well as a hand-held shower head for soaping and washing different parts of the body.

Type 1: Tub Diverter Valve
This type of shower diverter valve converts your tub into a shower. Its function is to redirect water from the tub spout to the shower head. There are actually at least three variations of this type of shower diverter valve:
Three-valve diverter.
You will find this shower diverter valve between the taps of a two-tap faucet. After using the hot and cold faucets to get the desired shower temperature, the diverter handle is turned clockwise to redirect the water flow to the shower head. Turning the handle counter-clockwise returns the flow to the tub.
Two-valve diverter.
This type of diverter has two L-shaped valves and can be located in the center of a faucet that adjusts water temperature with a single dial or between the taps of a two-tap faucet. Turning the handle redirects water from the tub spout to the shower head after the desired shower temperature is set.
Tee-diverter.
This diverter is the part of the tub spout. The diverter handle simply pulls straight up, sending all water from the tub spout to the shower head.
To reduce stress and wear on each type of valve, release the diverter and let water flow back into the tub once showering is complete, before shutting off the water.
If you are away from home and run into a shower diverter you’re not familiar with, always set your water temperature while standing outside the tub to avoid being scalded.
If your home shower has water flowing from both the tub spout and shower head, it’s probably time to call in a professional to clean or replace the shower diverter valve.
