A persistent drip from a tap might seem like a minor annoyance, but it can signal a larger issue—with water waste, rising bills, and potential damage to your bathroom infrastructure. Whether you’re attempting the repair yourself or deciding whether you need the expertise of emergency plumbers, understanding the steps and risks involved is key.
Why fix the drip now?
Even a slow trickle can waste a surprising amount of water over time. More importantly, what starts as a small drip in your bathroom can shed light on worn components or underlying plumbing issues. Ignoring the issue may lead to bigger problems—such as more serious bathroom leaks, compromised fixtures, or even water damage around the sink or basin.
When the job is DIY (and when it’s not)
Many dripping taps can be fixed with a handful of tools and replacement parts. That said, you should be ready to call in plumbing services—especially emergency plumbers—if things get beyond a simple washer change. Symptoms like ongoing dripping after repair attempts, low water pressure, or strange noises from your taps and pipes suggest a deeper issue, possibly within your home’s wider plumbing system.
Step-by-step: How to fix a dripping tap
Turn off the water supply: Before touching anything, isolate the water supply to the fixture. Often this means closing the stopcock or isolation valve beneath the sink. Then open the tap to relieve any residual water and pressure.
Remove the tap handle: Use a screwdriver (or the appropriate tool) to remove the handle screw. Some handles have a decorative cap concealing the screw. Once removed, lift off the handle carefully.
Loosen the valve or cartridge: With the handle off, use an adjustable spanner to loosen the valve or cartridge body. The exact internal setup depends on whether you have a traditional washer‐type tap or a modern cartridge/ceramic disc model.
Inspect the washer, O-ring or cartridge: For older style taps, a worn washer is the frequent culprit of drips. For newer mixer taps, damaged ceramic discs or cartridges often play the part. Also check the O-ring at the base of the spout—this seals around the moving parts and prevents leaks.
Replace the faulty parts: Swap out the worn or damaged component—new washer, new cartridge, or new O-ring as required. Ensuring you’ve got the right size and model for your tap is crucial.
Reassemble the tap: Put everything back together in reverse order. Make sure not to over-tighten fittings—this can create new issues, like cracking parts or stressing seals.
Turn the water back on and test: Restore the water supply and give the tap a good test. Look for any signs of continued dripping or leaks around the base and handle. If the drip persists, it’s time to call in expert plumbing services.
Common causes of a dripping tap
A worn or brittle washer: Over time, the rubber wears down, fails to seal properly, and allows water to seep through.
Faulty ceramic discs or cartridges: In modern taps, these are precision sealed parts; when damaged they cause dripping.
Worn O-ring around the spout: This small ring seals the moving parts; once compromised it allows water to escape.
Loose or corroded components: As taps age, screws, valve seats or spindles may become loose or corroded—leading to leaks.
Internal corrosion of the valve seat: When the seat becomes pitted, the seal is no longer perfect and the tap drips.
When you’ll need professional help
While many drips are fixable by a competent DIYer, there are times when it’s best to contact emergency plumbers or full-service plumbing professionals:
The tap keeps dripping despite replacement of washers or cartridges.
The water pressure is abnormally low or fluctuating, pointing to a larger plumbing issue.
You hear unusual noises (whistling, gurgling, hammering) that suggest air in the system or pressure issues.
You find corrosion, rust or damage beyond the easily replaceable parts.
The tap or plumbing system uses unfamiliar or specialised components you’re not confident handling.
In such cases, a full inspection by qualified plumbing services can identify hidden causes—perhaps an aging pipe, a failing valve, or a broader leak elsewhere in the system.
Preventative tips to avoid future drips
Perform regular checks on your taps and fix minor drips early before they escalate.
Avoid over-tightening handles, which can damage washers or seals.
Keep spare washers, O-rings and cartridges handy for quick swaps.
Use your taps gently—rough handling accelerates wear.
If you note a tap drip, act promptly: Much like spotting a small bathroom leak, early intervention avoids bigger damage and cost.
Final thought
A dripping tap might seem trivial at first, but it’s often a signal that your plumbing system needs attention. Follow the steps above to address it yourself, and if the problem persists or points to something more complex, consider reaching out to emergency plumbers or a reputable plumbing services provider. Doing so will restore your fixture, prevent waste, and protect your bathroom from further leaks and damage.
