Things You'll Need

  • Allen wrench

  • Adjustable wrench

  • Replacement rubber washer

A bathtub shower diverter is adjustable with a few turns of the wrench.

A bathtub shower combination features a diverter on or near the bathtub spout. The diverter allows you to choose whether you'd like water to come out of the shower head or the bathtub spout. After prolonged use, parts of the diverter can get worn out and cause drops of water to come out of the shower head while you're trying to fill the bathtub, or vice versa. You can easily adjust this yourself in a few minutes.

Step 1

Turn off the water supply to the washroom. Open the bathtub spout until water stops flowing.

Step 2

Look beside, underneath or on the bathtub spout for the diverter's holding screw. Loosen and remove the screw with an Allen wrench.

Step 3

Grasp the spout and pull it straight out. You may need to twist it slightly to the left and right.

Step 4

Unscrew the bolt holding the diverter to the small pipe in the wall. Pull out the diverter.

Step 5

Look inside the pipe in the wall or the end of the diverter for a rubber washer. It may have decayed over prolonged use.

Step 6

Remove the rubber washer with your fingers and replace it with a new one.

Step 7

Replace the diverter and bathtub spout in the reverse order of Steps 1 through 3.
