How to Fix a Leaking Shower Arm

If you notice a leak between the pipe and your shower head, it is most likely coming from your shower arm. Although this may seem daunting, fixing a leaking shower arm is quite simple and only takes a few minutes.

In this step-by-step guide, we will show you how to quickly fix a leaking shower arm so that you can get back to enjoying your showers.

Required Items Before Starting

  • Wrench: You will need a wrench to loosen the old shower arm and tighten the new one.
  • Plumbers Tape: This is a white, non-adhesive tape used to create a seal between two surfaces. This will be used to create a watertight seal between the new shower arm and the pipe.
  • Cloth: Use a soft cloth to avoid scratching them when cleaning or making repairs.
  • Cleaner (optional): Sometimes mold can build up on the shower arm due to exposure to moisture. If you see mold or mildew, you may want to clean the shower arm and showerhead when working.

Step 1: Remove the Shower Head

The first step is to remove the showerhead from the arm. To do this, you will need to use a wrench to loosen the connection between the two. Once you have loosened the connection, carefully remove the showerhead and set it aside.

Pro Tip: Wrap the neck of the showerhead in a towel; this will help prevent damage to the finish.

Step 2: Inspect the Shower Arm for Damage

Now that the showerhead has been removed, you can look at the shower arm. If you see any cracks or damage, you will need to replace the arm. We recommend checking out our guide on replacing a shower arm if this is the case.

However, if there is no visible damage, you can proceed to the next step.

Step 3: Clean the Shower Arm

Use a soft cloth to remove any dirt or debris on the shower arm, especially around the thread where it connects to the showerhead. You can use a cleaner such as bleach if there is any mold growth.

Step 4: Apply Plumber’s Tape

Plumber’s tape, also known as Teflon tape, is used to create a watertight seal between two metal threads. To apply the tape, simply wrap it around the shower arm thread a few times. Make sure to wrap it in the direction of the thread so that it will not come loose when you screw on the showerhead.

Step 5: Reattach the Showerhead

Now it is time to reattach the showerhead. First, align the showerhead with the arm and then screw it on. Use your wrench to tighten the connection until it is snug. Do not over-tighten as this can damage the threads and make it difficult to remove the showerhead in the future.

Step 6: Turn on Water and Check for Leaks

Once you have reattached the showerhead, turn on the water to check for leaks. If everything is tight and there are no leaks, you are all done! You can now enjoy your leak-free shower.
