Quick Answer:
If the showerhead keeps dripping after you turn the handle off, start by confirming the drops are actually coming from the nozzle (not condensation) and test with the handle fully off while noting how fast it drips. Small drips can mean a worn valve cartridge, a bad washer, or debris in the seat. Many drips are fixable with simple cleaning or a cartridge replacement, but persistent or heavy leaks should be handled by a professional.
Why This Happens
- Worn or damaged valve cartridge or washer: over time the seals inside the valve lose their ability to shut water off completely.
- Mineral deposits or debris: grit can keep the valve from seating, or block the showerhead and create slow leaks.
- Thermal expansion or pressure issues: occasional drips can be caused by pressure changes after hot water use.
- Loose showerhead or damaged threads: a loose connection can let water escape between uses.
- If the drip comes only after using the hot water, check Dripping only on hot side for causes focused on the hot-water side of the valve; if the fixture continues to run long after the shower is off, see Shower drips for hours after use.
Step-by-Step What to Do
1. Confirm the drip is from the showerhead
Dry the showerhead and surrounding area with a towel. Wait and watch for new drops to form. This rules out condensation on the metal or a leak from a different fitting.
2. Test with the handle fully off and note drip rate
- Turn the handle fully off (don’t leave it slightly open).
- Start a timer for one minute and count the drops, or note whether the drip is a steady stream, one drop every few seconds, or only an occasional drop.
- Record what you see — “one drop every 5 seconds” or “steady trickle” helps you judge severity.
3. Look for patterns
Does it drip only after hot water use, or all the time? Does it stop after a few minutes? Patterns point to specific causes (valve seals, temperature/pressure changes, or the showerhead assembly itself).
4. Check the showerhead and connections
- Hand-tighten the showerhead to ensure it isn’t loose. If it still drips, unscrew it and inspect the rubber washer and threads.
- Flush the pipe briefly into a bucket with the head removed to clear debris, then reinstall the washer and head.
5. Try simple cleaning fixes
- Soak the showerhead in a mild vinegar solution if mineral buildup is visible (remove per manufacturer’s instructions). Rinse thoroughly.
- Replace a worn rubber washer or inexpensive O-rings if they look flattened or cracked.
6. Inspect the valve cartridge (if comfortable)
If the shower still drips after cleaning and tightening, the valve cartridge or internal seals are often the culprit. Replacing a cartridge can stop the drip, but this requires shutting off the water supply, removing the handle and trim, and matching the correct replacement part.
7. Re-test and monitor
After any repair, dry the head, run and stop the shower, then observe with the handle fully off. Compare the new drip rate to your earlier notes.
What Not to Do
- Don’t assume a small drip is harmless — over time it wastes water and can point to a worn cartridge that will fail further.
- Don’t try forceful or improvised fixes that could damage the valve or plumbing (for example, repeatedly hammering fittings or overtightening plastic parts).
- Don’t ignore persistent leaks; if you can’t stop it with basic checks and simple fixes, a plumber is appropriate.
When to Call a Professional
- The drip continues after you’ve cleaned the head and replaced visible washers.
- Replacing a cartridge or valve appears necessary but you don’t have the correct parts, tools, or confidence to do the job safely.
- There’s a sign of water behind the wall, water stains, or rising water bills — these suggest a hidden leak that needs a pro.
- You smell gas or notice other major plumbing or structural issues while working — stop and call a professional.
Safety Notes
- Turn off the water supply before disassembling the valve or removing the showerhead; relieve pressure by running the shower briefly after shutting the supply.
- Use proper tools and protect finishes with cloths when using wrenches to avoid damage.
- Be careful with hot water — scalds can occur if you open lines without caution. Wear gloves and test water temperature slowly.
- If you are unsure about working on internal valves or plumbing behind walls, stop and call a licensed plumber.
Common Homeowner Questions
- Why does it drip only after I use hot water? Often a worn hot-side seal or thermal expansion causes the drip; check the hot cartridge and pressure/expansion settings.
- Can I just leave a slow drip? No — it wastes water and may mean a failing part that will worsen; fix it promptly or arrange for repairs.
- How expensive is a repair? Simple fixes like washers or cleaning are low-cost; cartridge or valve replacements vary by fixture and may be a moderate DIY or professional cost.
