How to Fix a Shower Diverter on a Tub Spout · Step 6 of 7
In this video
First, identify the signs of a faulty bathtub spout. The most common indicators are visible corrosion and water continuing to leak or drip from the spout even when the shower diverter knob is pulled up. This leak reduces water pressure to the showerhead. Determine how the spout is attached to the wall pipe by looking for a set screw on the bottom (slip-on type) or by seeing if the spout itself is threaded onto the pipe.
Goal: Bathtub Faucet Repair (Leaking Spout)
- There are three common types of spouts: one with a set screw underneath (often an Allen screw), one with a set screw on the side (often a flathead screw), and one that is threaded directly onto the pipe.

FAQs
Do I really need all the tools listed, like a torque wrench or patio furniture, for this project?
No, some listed tools are irrelevant for this specific project. You'll primarily need a utility knife or putty knife for caulk removal, a caulk gun for sealing, a rag/towel, and potentially an Allen wrench if your old spout has a set screw. Focus on plumbing-specific tools and materials.
What is the most important step to ensure a watertight seal for the new tub spout?
Thoroughly cleaning the pipe connection area is crucial. Remove all old caulk, debris, and corrosion before installing the new spout. After installation, apply a generous, continuous bead of silicone caulk around the base where the spout meets the wall to prevent water infiltration into the wall cavity.
How can I be sure to purchase the correct replacement tub spout?
First, determine if your existing spout is thread-on or slip-on by checking for threads inside the spout or a set screw underneath. Measure the pipe protrusion from the wall. Bringing your old spout or clear photos to the store will help ensure you get a new spout with the correct connection type and fit.
What should I do if water still drips from the tub spout when the shower is on after replacement?
If water still leaks, first re-examine your caulk seal for any gaps or imperfections. If the seal is good, ensure the new spout is fully engaged with the pipe connection; for threaded spouts, ensure plumber's tape was used and it's tightened properly. For slip-on spouts, verify the O-rings are seated correctly and the set screw is secure.
