When it comes to bathroom plumbing issues, faulty bathtub spouts and shower diverter valves can be a frustrating problem. The spout or diverter valve may leak, not shut off completely, or fail to direct water flow to the showerhead. Luckily, many issues can be resolved without calling a plumber. In this blog, we’ll explore some tips and tricks for troubleshooting faulty bathtub spouts or shower diverter valves.

  1. Identify the problem The first step in troubleshooting is to identify the problem. If your bathtub spout drips continuously or leaks while running the shower, the problem is likely a faulty diverter valve. If you have no water coming out of the showerhead, the problem could be a clogged showerhead or a faulty diverter valve. If water comes out of both the spout and showerhead simultaneously, the issue is with the spout.
  2. Check for obstructions Sometimes, mineral buildup or debris can clog the spout or diverter valve, causing water flow issues. To fix this, try removing the spout or diverter valve and clean them with vinegar or a lime dissolver. You can also use a small brush to scrub away any buildup.
  3. Replace the diverter valve If the diverter valve is the issue, it may need to be replaced. To do this, you’ll need to turn off the water supply to the shower, remove the old diverter valve, and install a new one. It’s essential to ensure that the replacement diverter valve is the same size and shape as the old one.
  4. Replace the spout If the problem is with the spout, it may need to be replaced. This is a relatively simple process that involves removing the old spout and installing a new one. You’ll need to ensure that the new spout is the same size and shape as the old one, and you may need to apply plumber’s tape to the threads to prevent leaks.
  5. Call a plumber If you’ve tried troubleshooting and still can’t resolve the issue, it may be time to call a plumber. They’ll have the tools and expertise to identify and fix the problem quickly.


Faulty bathtub spouts or shower diverter valves can be a headache, but with the right tools and knowledge, you can troubleshoot and resolve the issue. Remember to identify the problem, check for obstructions, replace the diverter valve or spout if needed, and call a plumber if all else fails. By following these tips and tricks, you can have your shower running smoothly in no time.
