How to Replace a Diverter in Your Bathroom Shower Easily

Have you ever turned your shower on, expecting a steady stream of water to spray from it, only to find that much of the water is still coming from the bath tap? That’s a sign that your bathroom diverter is breaking down. The diverter valve is a small but essential component of your shower system that diverts water from a spout to a showerhead. This can wear out with time, become clogged with mineral deposits, or otherwise stop working properly. The good news? You can fix it yourself!

What is a Bathroom Diverter?

The first step to replacing the diverter is to understand its purpose. The bathroom diverter is a valve that directs water either to the bath tap or the showerhead. When it’s working properly, it seals off the bath tap when you pull the lever, directing the flow of water up.

There are three common types of diverter valves:

1. Three-Valve Diverter – Generally seen in older systems, this type has individual hot and cold water knobs as well as a middle valve that diverts water to the shower.

2. Two-Valve Diverter – Seen in modern showers, this has one knob for adjusting temperature and another for toggling between the bath and shower.

3. Tub Spout Diverter – The most common design you will find, is where you pull a small lever or knob attached to the spout itself to send the water up to the showerhead.

Signs That Your Diverter Needs Replacing

Before replacing the diverter, check for common issues such as:

• Water leaking from the bathtub spout while the shower is running

• Difficulty in switching water flow between the showerhead and the tap

• Reduced water pressure when using the shower

If these problems persist despite cleaning or minor repairs, a replacement may be necessary.

Steps to Replace a Diverter in Your Bathroom Shower

Step 1: Turn off the water supply

First, turn off the water supply to prevent leaks or flooding while you work. If the bathroom does not have supply stop valves, turn off the main water supply.

Step 2: Remove the old diverter

The removal process depends on the type of diverter installed:

• Tub Spout Diverter: Turn it counterclockwise to unscrew the spout. If it doesn’t budge, check underneath to see if there’s a screw holding it down.

• Three-Valve Diverter: Unscrew the handle and remove the cover plate, which lets you access the diverter valve.

• Single-Valve Diverter: Unscrew knob and remove diverter cartridge.

Step 3: Install the new diverter

When you’ve removed the old diverter, clean the exposed pipe threads to remove debris or mineral deposits. Make it watertight by wrapping PTFE tape (Plumber's thread seal tape) around the threads. Screw and tighten new diverter tightly

Step 4: Reassemble and test the shower

Reattach the cover plate or tub spout and ensure all connections are secure. Turn the water supply back on and test the diverter by switching between the bath tap and the showerhead. Check for leaks and confirm smooth water flow.

What if Your Shower Diverter Still Leaks?

If you have replaced the diverter and still have leaks or weak pressure, there are a few things to look at:

• Make sure to install the new diverter valve correctly and tighten everything down.

• Inspect any washers or seals for damage and replace them as needed.

• Check the inside of the showerhead for mineral buildup, which can restrict water flow. Soaking it in vinegar overnight can help.

How Do You Maintain Your Diverter For a Longer Period?

To avoid frequent replacements, consider these maintenance tips:

• Regularly clean the diverter to prevent mineral build-up

• Check for leaks and address them early

• Avoid forcing the handle when switching the water flow
