Introduction
A dripping showerhead is one of those problems that seems minor but adds up quickly — both in wasted water and in the constant drip sound echoing through a small NYC bathroom. In most cases, the fix involves nothing more than cleaning mineral deposits, replacing a worn washer, or re-taping the threaded connection. NYC tap water contains minerals that build up inside showerhead components over time, gradually degrading seals and clogging flow passages. This guide covers the most common causes and how to fix each one.
Step-by-Step Instructions

Step 1 Tighten the Connection First
Sometimes a drip is simply caused by a loose connection between the showerhead and the shower arm (the pipe coming out of the wall). Wrap a cloth around the shower arm to protect the finish, then use an adjustable wrench to gently tighten the showerhead clockwise. Give it just a quarter turn past hand-tight. Over-tightening can crack the fitting or strip the threads, especially on older chrome-plated brass fittings common in NYC buildings. If tightening stops the drip, you are done.

Step 2 Remove and Inspect the Showerhead
If tightening did not help, unscrew the showerhead from the shower arm by turning it counterclockwise. You may need a wrench — again, protect the finish with a cloth. Inside the connection, you will see a small rubber washer or O-ring. Inspect it for cracks, flattening, or hardening. Also check the threads on both the showerhead and shower arm for corrosion or cross-threading. In older NYC apartments, shower arms can become corroded and pitted, which prevents any showerhead from sealing properly.

Step 3 Clean Mineral Deposits
Soak the showerhead in a bowl of white vinegar for two to four hours (or overnight for heavy buildup). The vinegar dissolves calcium and lime deposits that clog the internal passages and prevent the check valve from closing fully. Use an old toothbrush to scrub the nozzle face and clear each spray hole with a toothpick or safety pin. Rinse thoroughly with water. NYC's water is relatively soft compared to many cities, but minerals still accumulate over years of use, especially on showerheads that are seldom removed.

Step 4 Replace the Washer and Re-tape the Threads
Replace the rubber washer inside the showerhead coupling with a new one of the same size — bring the old one to the hardware store to match it. Wrap the shower arm threads with three to four clockwise layers of Teflon (PTFE) plumber's tape, overlapping each layer by half. The tape fills thread gaps and creates a watertight seal. Thread the showerhead back on by hand first, then snug it with a wrench. Restore water flow and check for drips at the connection and from the showerhead face with the water turned off.

Step 5 Check the Shower Valve if Dripping Continues
If the showerhead still drips after cleaning and re-sealing, the problem is likely the shower valve inside the wall rather than the showerhead itself. Turn off the shower completely and wait — if water continues to drip from the head, the valve cartridge or washers are worn and not fully shutting off water flow. While cartridge replacement is possible as a DIY project, accessing the valve requires removing the handle and trim plate, and the specific cartridge varies by manufacturer and model.
When to Call a Professional
Call a plumber if the drip continues after addressing the showerhead and connection, as the shower valve inside the wall needs service. Valve cartridge replacement involves working behind the wall and requires shutting off water to the unit — in many NYC buildings, this means coordinating with the super or building management to access the main shutoff. Also call a pro if the shower arm is corroded and cannot be unscrewed without risk of breaking the pipe inside the wall, which would require opening up the wall for repair.
