Drip, drip, drip.
A leaking shower head is more than a nuisance. It could spike your water bill — all those little drips add up! — and provide a permanent moist environment for mold and mildew.
Fortunately, fixing this problem is usually straightforward — no plumber needed (you can still call us if you want to)!
This guide will walk you through fixing a leaky shower head DIY.
Common Causes of a Leaky Shower Head
These are the most common culprits behind your shower woes:
1. Worn-Out Washer or O-Ring
The washer or O-ring inside your shower head creates a watertight seal. Any damage or age-related wear can cause a water drip.
2. Mineral Buildup
Hard water often leaves deposits that can clog the shower head. When the shower head is clogged, water may leak from places it shouldn’t.
3. Loose or Faulty Connections
The connections between the shower head and the pipe can loosen over time, allowing water to seep.
4. High Water Pressure
Excessively high pressure can force water out through weak spots in the shower head.
5. Cracked Shower Head or Pipe
Wear and tear can crack the shower head or the connecting pipe, especially if they’re made of older or cheaper materials.
Tools You’ll Need
- Adjustable wrench or pliers
- Screwdriver (if required for your shower model)
- Replacement washer or O-ring
- Teflon tape (also known as plumber’s tape)
- Vinegar (for mineral buildup removal)
- Toothbrush or small brush
- Bucket or bowl (to soak the shower head)
- Soft cloth or towel
Step-by-Step Guide to Fix a Leaking Shower Head
1. Turn Off the Water Supply
Turn off the water supply to the shower unless you plan to get sprayed.
2. Inspect the Shower Head
- Unscrew the shower head from the wall pipe
- Inspect it for cracks, clogs, or damage.
- Use a wrench or pliers if the shower head is tightly attached, but wrap the tool in a soft cloth first to avoid scratching the finish.
3. Remove Mineral Deposits
- Fill a bowl or bucket with equal parts vinegar and water.
- Submerge the shower head in the solution and leave it to soak for at least 20 minutes. For stubborn buildup, soak it for an hour or more.
- Scrub off any remaining deposits with a toothbrush.
- Rinse the shower head thoroughly with running water.
4. Replace the Washer or O-Ring
If the leak persists after cleaning, the washer or O-ring could be the issue:
- Open the shower head by unscrewing the front face or cap (if applicable).
- Locate the rubber washer or O-ring inside the shower head.
- Remove the worn washer or O-ring and replace it with a new one that fits your shower model.
- Reassemble the shower head.
5. Apply Teflon Tape to Threads
If the connection is loose, wrap Teflon tape around the threads of the shower arm (the pipe extending from the wall). The tape will create a watertight seal.
- Use about 2–3 wraps of Teflon tape around the threads. Make sure it’s snug but not overly tight.
- Screw the shower head back onto the pipe and tighten gently with your hand or wrench.
Step 6. Check Water Pressure
Test the shower after reassembling it. If the leak persists, high water pressure might be the issue.
- Consider installing a pressure regulator or calling a plumber to adjust the pressure.
7. Inspect for Cracks
If the shower head still leaks, thoroughly inspect it and the connecting pipe for any cracks or damage.
- If you find any, replace that part immediately.
Tips to Prevent Future Leaks
- Clean your shower head regularly to prevent mineral buildup.
- Be gentle when tightening connections. Over-tightening can damage them.
- Use a water pressure gauge to monitor and keep your water pressure within safe levels (40–60 psi).
- Replace old or damaged parts as needed instead of waiting until they cause a bigger problem.
What to Do If the Shower Faucet Handle Is Leaking
1. Turn Off the Water Supply
Shut off the water supply to avoid further leaks or flooding.
2. Remove the Handle
- Remove the screw holding the handle in place.
- Gently pull the handle off to expose the valve or cartridge.
3. Inspect the Cartridge or Valve
- Look for wear, cracks, or damage in the cartridge or valve.
- If necessary, consult your faucet’s manual to identify the correct replacement part.
4. Replace the Cartridge or Valve
- Remove the damaged cartridge or valve using pliers or an appropriate tool.
- Install the new cartridge or valve and ensure it is secure.
5. Reassemble the Handle
- Reattach the handle and tighten the screw securely.
- Turn the water supply back on and test for leaks.
6. Apply Teflon Tape to Threads (Optional)
Use Teflon tape to ensure a watertight seal if there are threaded connections.
FAQs: Stopping a Shower Head from Leaking
Q: How do I know if the problem is with the shower head or pipe?
If tightening connections and replacing washers don’t stop the leak, the issue might lie in the pipe itself. Inspect for cracks or corrosion.
Q: Can I use any washer or O-ring to replace the existing one?
Buy a washer or O-ring compatible with your shower head model to ensure a good fit.
Q: What causes mineral buildup in shower heads?
Mineral buildup occurs when hard water deposits calcium, magnesium, and other minerals inside the shower head.
Q: Is using a metal brush to clean the shower head okay?
Avoid metal brushes, which can scratch the finish on your shower head. A toothbrush or soft brush works best.
Q: How much does it cost to replace a shower head?
Shower heads can range from $20 for basic models to over $200 for high-end options.
Q: How often should I clean my shower head?
It’s a good practice to clean your shower head once a month to prevent clogs and leaks.
