A leaking shower head might seem like a minor annoyance, but over time, those persistent drips can lead to wasted water, higher utility bills, and even potential damage to your bathroom fixtures. If you’ve noticed water trickling down long after you’ve turned off the tap, you’re not alone—many homeowners face this common issue. Fortunately, stopping a shower head from leaking is often a straightforward fix that doesn’t require calling in a professional.

Understanding why your shower head is leaking is the first step toward a lasting solution. Leaks can stem from worn-out washers, mineral buildup, or loose connections, among other causes. By identifying the root of the problem, you can take targeted action to restore your shower’s performance and prevent further water waste.

In the following sections, we’ll explore practical tips and easy-to-follow methods to help you tackle a leaking shower head. Whether you’re a seasoned DIYer or a beginner looking to save money, you’ll find valuable guidance to get your shower back to its drip-free best.

Inspecting and Replacing the Washer

A common cause of a leaking shower head is a worn-out washer inside the connection between the shower head and the shower arm. Over time, washers degrade and lose their ability to form a tight seal, allowing water to seep through.

To inspect and replace the washer, start by turning off the water supply to the shower. Unscrew the shower head from the shower arm using an adjustable wrench or pliers, protecting the finish with a cloth to avoid scratches. Once removed, locate the rubber or silicone washer inside the shower head fitting.

If the washer appears cracked, flattened, or brittle, it needs to be replaced. Washers are inexpensive and available in most hardware stores. When installing a new washer, ensure it sits flat and snug within the fitting to create an effective seal.

Applying Plumber’s Tape Correctly

Plumber’s tape, also known as Teflon tape, is a crucial component in preventing leaks where threaded connections join. Its purpose is to fill any small gaps and create a watertight seal.

Before reattaching the shower head, wrap the threads of the shower arm with plumber’s tape. Use the following guidelines:

  • Wrap the tape clockwise around the threads to match the direction of the shower head’s threading.
  • Apply 2 to 3 layers of tape, ensuring even coverage without overlapping excessively.
  • Press the tape firmly into the threads to avoid bunching.

This simple step significantly reduces the likelihood of leaks caused by thread imperfections or minor damage.

Cleaning the Shower Head to Remove Mineral Deposits

Mineral buildup, especially from hard water, can clog the shower head nozzles and cause leaking or dribbling. Regular cleaning helps maintain proper water flow and prevents leaks caused by pressure irregularities.

To clean the shower head:

  • Detach the shower head from the arm.
  • Soak it in a vinegar solution (equal parts white vinegar and water) for several hours or overnight. Vinegar dissolves mineral deposits effectively.
  • Use a soft brush or toothbrush to scrub away loosened deposits.
  • Rinse thoroughly with clean water before reinstalling.

If the shower head has non-removable parts, fill a plastic bag with vinegar solution, submerge the head, and secure the bag with a rubber band to soak.

Checking and Tightening Connections

Loose connections are a frequent cause of leaks at the shower head. After replacing washers and applying plumber’s tape, ensure all fittings are tightened correctly.

Use an adjustable wrench to snugly tighten the shower head onto the shower arm, but avoid overtightening, which can damage threads or crack components. If a leak persists after tightening, disassemble and reapply plumber’s tape and washer to ensure proper sealing.

When to Replace the Shower Head

If leaks continue despite maintenance efforts, the shower head itself may be damaged or worn beyond repair. Cracks, corrosion, or internal component failure can render a shower head defective.

Consider replacing the shower head if:

  • You observe visible cracks or corrosion.
  • The leak persists after replacing washers and applying plumber’s tape.
  • Cleaning does not improve water flow or stop drips.

Modern shower heads offer various features, such as water-saving designs and adjustable sprays, making replacement an opportunity to upgrade.

Common Causes of Shower Head Leaks

Understanding the root causes of leaks helps target the correct repair method. Below is a summary of typical reasons for shower head leaks:
