In this video
Return to the main water shut-off valve and turn it counter-clockwise to slowly restore water to the house. You may hear pipes gurgling as they refill. Once the water is back on, go to the shower and turn the handle to test the newly installed cartridge. Check for proper hot and cold water flow and, most importantly, turn the faucet off and check for any leaks from around the handle or out of the tub spout. If there are no leaks and the faucet operates smoothly, the repair is complete.
Goal: Verify the repair
- Turn the water back on slowly to avoid a 'water hammer' effect, which can damage pipes.

FAQs
What's the most common reason for a shower diverter to fail, and do I always need to replace the entire tub spout?
A failing shower diverter is usually due to worn internal components like rubber seals or springs, causing water to escape through the tub spout even when the shower is engaged. While some diverters can be repaired with specific replacement kits, replacing the entire tub spout is often the most reliable and straightforward solution for a lasting fix, especially for beginners.
What specific tools and materials are essential for replacing a tub spout diverter, and are there any common misconceptions about what's needed?
You'll primarily need a new tub spout with a diverter, plumber's putty for threaded spouts, silicone caulk for sealing, and a hex key or adjustable wrench depending on your current spout's attachment. A utility knife is useful for removing old caulk. Focus on these plumbing essentials and disregard unusual items like outdoor furniture or rodent repellent sometimes listed with general project guides.
How difficult is this project for a beginner, and how long should I realistically expect it to take?
This project is rated as beginner-friendly because it generally involves basic steps like unscrewing or prying, cleaning, and re-sealing, without needing to open walls or solder pipes. While estimated at 2 hours, allow extra time for diagnosing your specific spout type, thoroughly removing stubborn old caulk, and ensuring a proper, leak-free seal. Patience helps ensure a quality result.
What are the most common mistakes beginners make when replacing a tub spout, and how can I avoid them?
A common mistake is not correctly identifying whether your old spout is threaded or a slip-on type, leading to buying the wrong replacement. Another error is neglecting to thoroughly clean and prepare the pipe stub-out, which can prevent a secure, leak-free seal. Always dry-fit the new spout first and ensure the pipe is pristine before applying caulk or putty.
