In this video
Turn on the water supply to the shower. Pull up the diverter on the tub spout to direct water to the showerhead. Check all connection points—where the shower arm enters the wall and where the showerhead attaches to the arm—for any drips or leaks. If a leak is present, turn off the water and slightly tighten the leaking connection.

FAQs
How difficult is replacing a tub spout diverter, and how long does it typically take a beginner?
This project is considered beginner-level for most DIYers and is typically completed within two hours. The process is straightforward, focusing on careful removal of the old spout and ensuring a proper, leak-free seal with the new one.
What specialized tools or materials will I absolutely need to replace my tub spout diverter?
You will primarily need a new diverter tub spout, plumber's tape, and silicone caulk with a caulk gun. Depending on your current spout's installation, an Allen wrench (hex key) might be necessary to loosen a set screw for removal. Rags and towels are also essential for cleanup and protecting your tub.
What's the most common mistake DIYers make when installing a new tub spout, and how can I avoid leaks?
The most common mistake is failing to create a proper seal, leading to leaks behind the wall or around the spout's base. To avoid this, thoroughly clean the pipe stub, apply plumber's tape correctly to threaded connections, and generously caulk the gap between the new spout and the wall.
Can I just repair the diverter mechanism inside my existing tub spout instead of replacing the whole thing?
For most modern tub spouts, especially slip-on or screw-on types, the diverter mechanism is an integrated component of the spout assembly. It cannot be easily repaired or replaced separately. Replacing the entire tub spout is generally the most straightforward and reliable solution for a broken diverter.
