How To Change A Tub Spout Diverter

How to Change a Tub Spout Diverter: A Step-by-Step Guide

Replacing a broken or worn-out tub spout diverter is a relatively straightforward plumbing project that can save you money on costly plumber fees. This guide provides a detailed, step-by-step process for changing your tub spout diverter, equipping you with the knowledge and confidence to tackle this home improvement task. This process applies to most standard tub/shower diverter valves, but always refer to your specific manufacturer's instructions if available. Safety precautions are paramount, so remember to turn off the water supply before beginning.

What you'll need:

• New tub spout diverter: Ensure it's compatible with your existing plumbing setup. Take your old diverter with you to the hardware store for accurate matching.
• Screwdriver(s): Phillips head and flathead are usually necessary.
• Adjustable pliers: For gripping and loosening stubborn fittings.
• Plumber's putty: To create a watertight seal around the new diverter.
• Old towels or rags: To protect your tub and catch any dripping water.
• Bucket or container: To catch any remaining water in the pipes.
• Flashlight: To illuminate hard-to-see areas.
• Optional: Teflon tape: For added security on threaded connections.

Step-by-Step Instructions:

1. Turn Off the Water Supply

This is the most crucial step. Locate the shut-off valves for both the hot and cold water lines supplying your tub. Turn them clockwise to completely shut off the water flow. To be absolutely sure, run the faucet to drain any remaining water in the lines.

2. Remove the Old Diverter

Remove the spout handle: Carefully remove any decorative caps or screws securing the handle to the spout. Often, these are concealed under the handle itself. Use a screwdriver or your fingers to gently pry them off.

Disconnect the spout: Locate the connection nut holding the spout to the diverter valve. This is usually found behind the handle. Use adjustable pliers to carefully loosen and remove the nut. You may need to work it back and forth gently to break the seal. Sometimes, a flathead screwdriver can be helpful for leverage.

Remove the diverter valve: Once the nut is removed, the old diverter should come loose. You might encounter some resistance due to mineral buildup or corrosion. Use gentle but firm pressure to remove the old diverter. Be careful not to damage the valve body during this process. Take note of how the parts are assembled; this will help you with reassembly.

3. Prepare the New Diverter

Inspect the new diverter for any included gaskets or O-rings. These are crucial for a proper seal. Apply a small amount of plumber's putty around the base of the new diverter, ensuring a consistent and even layer. This will create a waterproof seal.

4. Install the New Diverter

Insert the diverter: Carefully insert the new diverter into the valve body, aligning it correctly. Push it firmly and securely into place.

Tighten the connection nut: Replace the connection nut and tighten it carefully using adjustable pliers. Don't over-tighten, as this can damage the diverter or the valve body. A snug fit is all you need.

Reattach the handle: Replace the handle and any decorative caps or screws.

5. Turn the Water Supply Back On

Slowly turn the hot and cold water supply valves counterclockwise to restore the water flow. Carefully check for any leaks around the new diverter and the connection nut. If you notice any leaks, tighten the connection nut slightly or reapply plumber's putty. If the leak persists, you might need to revisit the installation process.

6. Test the Diverter

Test the functionality of the new diverter by switching between the tub spout and showerhead. Verify that the water flows correctly to both.

Troubleshooting:

• Leaking: If you notice a leak, it's likely due to a poorly tightened connection or insufficient plumber's putty.
• Diverter doesn't switch: Ensure the diverter is correctly installed and the handle is operating correctly.

This comprehensive guide should help you successfully change your tub spout diverter. Remember to always prioritize safety and take your time. If you are uncomfortable performing this repair yourself, it's always best to consult a qualified plumber.
