A leaking or corroded shower arm is the pipe between the wall and the showerhead. Here is the New Berlin guide.
The arm
The arm threads into a fitting in the wall and the showerhead threads onto it.
The leak
Water dripping from behind the head or down the wall is usually the arm or its connection.
The fix
Unscrew the old arm, wrap the threads with tape, and thread on the new one.
The call
If the fitting inside the wall is bad, call a pro. Call 888-217-3585 and New Berlin Plumbing Pros will match you with a New Berlin plumber.
Before you start
For New Berlin homeowners, first identify whether the symptom is isolated to one fixture or appears across the home. Note when it happens, what fixtures were running, and whether the main shutoff is accessible. Photos and model numbers help a professional make a faster, more accurate recommendation.
A simple decision checklist
Before approving work in Waukesha County, ask what caused the problem, which repair options were considered, what access or permit work is included, and how the finished work will be tested. Confirm the scope, materials, cleanup, warranty, and price in writing.
When to stop DIY work
Stop troubleshooting if water is near electricity, sewage is entering the home, a gas appliance is involved, a pipe may be frozen inside a wall, or the repair requires opening a structural surface. Shut off water when safe and call a qualified professional.
