How to Fix a Leaky Shower Head: A Step-by-Step Guide

How to Fix a Leaky Shower Head: A Step-by-Step Guide

That constant drip-drip-drip isn’t just irritating—it’s also a major water waster! If your shower head is leaking, don’t worry. With a few simple tools and a little patience, you can fix it yourself in no time.

Before you begin, figure out whether the leak happens when the faucet is ON or OFF:

  • Faucet ON? Your shower head holes may be clogged with mineral buildup. Cleaning or replacing the shower head should fix the issue.
  • Faucet OFF? The problem likely lies with the faucet cartridge inside the valve. You’ll need to replace it to stop the leak.

Now, let’s go step by step to get your shower back in perfect shape!

How to Repair a Leaky Shower Head

What You’ll Need

Tools:

  • Small scrub brush
  • Plastic bowl
  • Channel-lock pliers (if needed)
  • Hex wrench set
  • Screwdrivers
  • Utility knife

Materials:

  • White vinegar
  • Thread-sealing tape
  • Replacement shower faucet cartridge (if needed)
  • Towel (optional)

Step 1: Remove the Shower head

First, make sure the shower faucet handle is completely OFF. Then, unscrew the shower head from the shower arm by turning it counterclockwise.

Pro Tip: If the shower head won’t budge, wrap a damp washcloth around it for a better grip. Still stuck? Use channel-lock pliers, but be gentle to avoid damaging the finish.

Step 2: Inspect and Clean the Shower Head

Take a close look inside the shower head. You should see rubber O-rings, a screen, and other small parts. If they’re damaged, replace them.

For mineral buildup:

  • Soak the shower head in a bowl of white vinegar for at least one hour.
  • Scrub it clean with a small brush and rinse thoroughly.

Step 3: Wrap the Pipe Threads

Before reattaching the shower head, clean the shower arm’s threads with a scrub brush. Then, wrap 1-2 loops of thread-sealing tape (also called plumber’s tape) around the threads in a clockwise direction. This helps create a tight seal.

Step 4: Reassemble and Test the Shower Head

Screw the shower head back onto the shower arm by hand. Turn the shower on briefly to check if the leak is gone.

  • If the leak continues only when the water is on, the shower head might be too old or damaged—consider replacing it.
  • If water dribbles out even when the faucet is OFF, the issue is likely with the faucet cartridge. Let’s fix that next!

How to Replace a Faulty Shower Cartridge

A worn-out cartridge inside the faucet valve can let water leak through even when the faucet is off. Replacing it isn’t too difficult—just follow these steps.

Step 1: Shut Off the Water

Look for shutoff valves behind a wall panel near your shower. If you can’t find any, turn off the main water supply for your home.

Step 2: Remove the Faucet Handle

  • Look for a small cap at the center of the handle. Use a screwdriver or utility knife to pop it off.
  • Unscrew the handle screw and pull the handle off. You may need a hex wrench, depending on your faucet type.

Step 3: Take Off the Escutcheon Plate

The escutcheon plate is the large cover behind the handle. Remove its screws and carefully cut through any caulk sealing it to the wall. Once loose, pull it off.

Step 4: Remove the Retaining Clip

The shower cartridge is held in place by a U-shaped metal clip. Use a flathead screwdriver to pry it out. Some models also have a hex nut—unscrew it if needed.

Pro Tip: Some manufacturers sell cartridge puller tools to make removal easier.

Step 5: Slide Out the Old Cartridge

Gently pull the cartridge straight out. If it’s stuck, grip the stem with channel-lock pliers and twist slightly as you pull.

Step 6: Install the New Cartridge

  • Align the new cartridge’s tab with the groove inside the faucet body.
  • Slide it in until it’s fully seated.
  • Reinsert the retaining clip and any washers you removed.

Step 7: Reassemble and Test

Put the escutcheon plate and handle back in place, then turn the water back on. Test the shower by turning it on and off several times to make sure the leak is gone.

Final Thoughts

Fixing a leaky shower head isn’t just about stopping that annoying drip—it also saves water, lowers your bill, and prevents long-term damage to your plumbing. Whether it’s a simple mineral buildup or a faulty cartridge, following these steps will get your shower back in top shape.
