The diverter valve is the device that changes the flow of water from your tub’s faucet to the showerhead. In many instances, the valve will not fully move one way or the other and you’ll have water coming out of both fixtures.
If you choose to work on this problem yourself you’ll need to be very careful. If you use too much force you could cause a great deal of damage that will be expensive to repair. However, if you feel comfortable with this type of plumbing job and you have the tools and experience, you should be able to handle it on your own.
You’ll simply need to remove the valve knob by either unscrewing it or using a gear puller. If the knob won’t come off and you don’t have a gear puller, lightly – very lightly – tap on the back of the knob. Stop immediately and call a plumber if you are not willing to do this. When you take off the knob and put on the new one, make sure it is pointed in the right direction.
