How to Fix Different Tub and Shower Controls

Controls for tubs and showers are similar to those for sink faucets. Both operate in a similar manner. So, they are simply repaired in the same way that you would normally repair your faucets. The only difference is that you’ll be working horizontally instead of vertically this time.

The tub and shower controls are also a little tricky because they divert water to the tub spout and the showerhead. In other cases, their pieces are difficult to reach, and repairing them may include chipping away at the tiles. If your shower control body is broken and has to be replaced, look on the opposite side of the wall for an access panel. If you are fortunate enough to find one, you can simply work from there to reduce the amount of damage to your shower wall.

Before starting any repairs, check sure the supply stop valves or built-in shutdown valves are closed.

Ball control with a single hand

The revolving ball faucet, which also has seals and springs, is a good example of this. When you elevate the ball’s handle, the apertures connect with the supply line ports, allowing water to flow through and out the spout.

If only a small amount of water pours out of the spout, material obstructing the apertures or old seals could be to blame. You must remove the debris, clean out the holes, and replace the worn parts to solve this problem.

Turn off the water supply before you begin repairs. Remove the setscrews that are holding the ball in place. Remove the ball after they’ve been removed. Clean out all of the cracks and scrape out any muck that may have accumulated. Replace any damaged seals or rubber pieces, then coat them in heatproof oil. Examine the ball for signs of wear and corrosion. If this is the case, you should consider getting a new one.

Two-handle control

Stems with washers are commonly used in this form of control. To keep the water from running out the spout, each washer is placed on a seat. A leaking washer could be the cause. Remove the stem from a leaky shower control to stop it from leaking. You may need to use a specific stem wrench or a deep socket wrench to accomplish this.

In some circumstances, you’ll need to chip away at the tiles to solve the problem. Remove the screws that hold the washer in place after removing the stem, and then pull the washer out. Remove all debris from the stem. Obtain a washer that is the same size and shape as the old one. Insert the new washer into the stem’s bottom. Once you’ve found the perfect fit, reinstall the screws to keep it in place. Tighten them as much as you can, but don’t overtighten them. After that, replace the stem. However, if the diverter valve on the spout is broken, you may need to replace the spout right away.
