How to Fix a Shower Diverter on a Tub Spout · Step 5 of 5
This guide provides instructions for fixing a faulty shower diverter located on a tub spout. The most common issue is water leaking from the spout when the shower is engaged. The typical solution is to remove the old tub spout and replace it with a new one, as repairing the internal diverter mechanism is often not practical or possible.

FAQs
How difficult is it to replace a tub spout diverter, and how long should I expect the project to take?
Replacing a tub spout is generally a beginner-friendly plumbing project, as it mostly involves removal and reinstallation. The most time-consuming part can be removing a heavily caulked or corroded old spout. You should budget about 1-2 hours for the entire job, assuming you have the correct replacement parts and tools ready.
Why is it recommended to replace the entire tub spout rather than just repairing the diverter mechanism?
Most tub spout diverters are integrated directly into the spout itself and are not designed for easy disassembly or repair. Attempting to fix the internal mechanism is often more complicated, time-consuming, and less reliable than simply replacing the entire unit with a new one. A new spout guarantees a fresh, fully functional diverter.
What specific tools will I need to successfully remove my old tub spout and install a new one?
You'll primarily need a wrench for threaded spouts or a screwdriver (like the Milwaukee Precision Phillips/Slotted Flat Head Combination Screwdriver Set) for spouts with a set screw underneath. A utility knife (e.g., Husky Pro Utility Knife) is essential for cutting away old caulk, and a caulk gun (JES 1 Qt. 26:1 High-Thrust Caulk Gun) with silicone sealant (GE Tub and Tile Silicone 1 Caulk) is required for sealing the new spout.
How do I ensure I purchase the correct type of replacement tub spout for my existing plumbing?
The most critical step is to determine if your current spout is a 'slip-fit' (secured by a set screw underneath) or 'threaded' (screws directly onto a pipe stub-out). Measure the length of the pipe stub-out from the wall if it's threaded. You can often find universal 'slip fit and IPS connection' models like the DANCO Diverter Tub Spout, which fit both common types. Bringing your old spout or clear photos to the store can also help ensure a correct match.
