Fixing a Leaking Shower Head Connection

Water dripping from the base of your shower arm is not just a waste of resources, it is a slow-motion disaster for your wall finish and sub-flooring. Most homeowners ignore this until the drywall behind the shower begins to show signs of moisture, but the fix is one of the most straightforward plumbing tasks you can tackle with a single tool. Done well, this repair creates a watertight seal that lasts for years. You are looking to reset the threaded connection where the shower arm meets the pipe inside the wall, ensuring the threads are clean and properly sealed with fresh tape. Precision matters more than force here; over-tightening is the primary way people turn a small leak into a snapped pipe inside their wall.

  1. Protect the chrome finish. Wrap the shower arm with a thick rag or a piece of heavy rubber before applying any tools. This prevents the wrench from scratching the finish of your chrome or brushed nickel arm.
  2. Unscrew with steady support. Using an adjustable wrench, turn the shower arm counter-clockwise to unscrew it from the drop-ear elbow inside the wall. Once it is loose, unscrew it by hand until it is completely removed.
  3. Strip old tape completely. Use a stiff wire brush to scrub away the old, crusty plumber's tape or dried-up pipe dope from both the shower arm threads and the wall-side pipe threads. Wipe everything clean with a dry cloth to ensure no debris remains.
  4. Wrap three times clockwise. Wrap plumber's PTFE tape around the threads of the shower arm in a clockwise direction. Apply 3 to 4 full wraps, pulling the tape tight so it conforms to the grooves of the threads.
  5. Thread back with caution. Hand-thread the shower arm back into the wall pipe until it feels snug. Finish the turn with your wrench, ensuring the shower head points straight down, but stop immediately if you feel heavy resistance.
  6. Confirm the seal holds. Turn on the shower for one minute to check the seal under pressure. If water still appears at the base, turn off the water and repeat the taping process with one additional layer of tape.
