If your shower head diverter isn’t working properly, it can turn your daily shower into a frustrating experience. Whether water is leaking from the tub spout while you’re trying to shower or the diverter is stuck, fixing the issue is easier than you might think. In this guide, we’ll walk you through how to fix a faulty shower head diverter quickly and effectively.

What Is a Shower Diverter?

A shower diverter is a valve that directs water from the tub spout to the shower head. It’s typically located on the tub spout itself or as a separate control on the shower valve. Over time, diverters can wear out, become clogged with mineral deposits, or get stuck due to corrosion or broken parts.

Common Signs Your Shower Diverter Is Broken

• Water leaks from the tub spout while the shower is on
• The diverter knob is stuck or hard to pull
• Reduced water pressure from the shower head
• Water won’t switch to the shower head at all

Step-by-Step Guide to Fix a Shower Diverter

1. Identify the Type of Diverter

There are three main types:

• Tub Spout Diverter: Located directly on the spout
• Three-Valve Diverter: Found in older showers with separate hot and cold knobs
• Single-Valve Diverter: Common in newer showers with a single handle

Knowing your diverter type will help you determine how to fix or replace it.

2. Turn Off the Water Supply

Before starting any repair, shut off the water to avoid accidental leaks or flooding.

3. Remove the Diverter

If you have a tub spout diverter:

• Unscrew the tub spout with a wrench or twist it off (depending on the model).
• Remove any visible screws or securing pins.

For in-wall diverters:

• Use a screwdriver to remove the handle and trim plate.
• Unscrew the diverter valve with a wrench.

4. Clean or Replace the Diverter

• Soak the diverter in white vinegar to remove mineral buildup.
• If parts are broken or worn, replace the diverter with a new one from your local hardware store.

5. Reinstall the Diverter

• Carefully reinstall all parts in the reverse order.
• Use plumber’s tape on threaded connections to prevent leaks.

6. Test Your Shower

Turn the water back on and test the diverter by switching between the tub and shower. Ensure there’s no water leaking and that the diverter operates smoothly.

When to Call a Plumber

If the diverter is behind the wall or you notice other plumbing issues like low water pressure, leaking pipes, or mold, it’s best to call a licensed plumber to avoid further damage.
