Leaking tap repair is usually easier and less expensive when you identify where the water is escaping before buying parts or replacing the faucet. A drip from the spout, a leak around the handle and water under the sink can have different causes, even when they seem to come from the same fixture. First dry the tap and surrounding area, then watch when the leak appears. A worn washer, cartridge or seal may need replacing; a loose connection or damaged faucet body may call for a different fix. If you can’t locate the source, the shut-off valves won’t turn, or the repair feels beyond your experience, ask a handyman or plumber to assess it.
Dry the faucet, sink and cabinet below it. Run the tap briefly, turn it off and check again with a tissue or dry paper towel. Look at the spout, handle, faucet base, supply lines and shut-off valves. Note whether the leak happens while the water is running, after you turn it off, or even when the tap hasn’t been used.
That timing is a clue, not a diagnosis. Water can travel along a faucet or pipe before it drips, so the wettest spot may not be the source. If water appears under the sink only while the tap is running, check the drain and waste connections as well as the water supply: a drain leak can be mistaken for a tap leak.
| What you notice | Possible cause | What to check |
|---|---|---|
| Water keeps dripping from the spout when the tap is off | Worn washer, cartridge, valve seal or debris around a sealing surface | Confirm the handle is fully closed and observe whether the drip continues. Identify the faucet type before buying a part. |
| Water appears around a handle during use | Worn O-ring, stem seal, cartridge or loose component | Dry the handle and faucet body, then watch closely while turning the tap on and off. |
| Water collects around the faucet base | A seal, mounting area or nearby connection may be leaking | Check whether water appears only during use and trace it back toward the handle or supply lines. |
| Cabinet floor or pipework below the sink is wet | Supply hose, shut-off valve, drain connection or water running down from the faucet | Dry each part and check separately while running the tap, then while draining water from the sink. |
| Water sprays or runs around the spout only while open | Loose or damaged spout connection, or a flow issue at the outlet | Check the spout and its connection. A dripping outlet after the tap is closed points to a different problem. |
Faucets don’t all seal in the same way. Some use a compression stem and washer; others use a cartridge, a ball assembly or ceramic discs. The right repair depends on the faucet’s design and, in many cases, its make and model. A replacement part that looks similar may not fit or seal correctly.
These are useful clues, not a guarantee of what has failed. Look for a brand name or model marking on the faucet, handles, packaging or installation paperwork. If you can’t find it, take clear photographs of the whole faucet and its controls, along with any part you remove, before asking a hardware supplier or repair professional to help identify a match.
Try a DIY repair only if you can identify the faucet, reach its shut-off valves and work without forcing stuck or corroded parts. If the faucet is under warranty, check the manufacturer’s repair instructions before disassembly. Renters should also ask the landlord or property manager before carrying out a repair that could affect the fixture or plumbing.
If the leak continues, shut the water off again and check that the part is compatible and seated correctly. A damaged valve seat, faucet body, connection or different failed seal may be responsible. Repeatedly tightening fittings or disassembling the faucet without identifying the cause can damage parts and turn a small repair into a larger one.
Professional help makes sense when the leak is difficult to trace, the faucet is unfamiliar, replacement parts are hard to identify, or you’re not comfortable isolating the water. A handyman who handles minor plumbing repairs may be suitable for a straightforward faucet inspection or component replacement. Ask about their experience with the faucet type and whether they can source a compatible part. A plumber may be more appropriate if the leak involves pipework, a failed shut-off valve, a damaged connection or a problem that extends beyond the fixture.
Stop and seek help if a shut-off valve is stuck, leaks when operated, or doesn’t stop the flow. Don’t continue working if you find badly corroded parts, a cracked faucet body, water escaping inside a wall or cabinet, or a leak you can’t safely contain. If water reaches electrical equipment or an outlet, keep clear of the wet area and get qualified help rather than handling the equipment.
When arranging a service, describe where the water appears and when it happens. Photos or a short video can help explain the issue. Ask whether the initial visit includes diagnosis, how parts are handled, and whether any repair or replacement recommendation will be discussed before work proceeds. These questions help you understand the proposed work without assuming that every drip requires a new faucet.
A targeted repair is often worth investigating first when the faucet is otherwise in sound condition and the failed part can be identified. Replacing a washer, seal or cartridge may avoid the expense and disruption of changing the whole fixture. But repair isn’t always the better choice: the model may be difficult to source, several components may be worn, or the faucet body or mounting may be damaged.
| Option | May suit | Main advantage | Limitation |
|---|---|---|---|
| Replace a washer or seal | A faucet with an identifiable, replaceable seal and no obvious body damage | Targets a small, specific failure | Works only if the seal is the cause and the sealing surfaces are in usable condition |
| Replace a cartridge or internal assembly | A faucet with a compatible replacement part available | Can address wear in the operating mechanism without changing the whole fixture | Correct identification and fit matter; a misfitted part may still leak |
| Replace the faucet | A damaged fixture, hard-to-source mechanism or repair that isn’t practical | Replaces the complete unit rather than one internal component | Requires a larger job and may involve access, connections and sink compatibility |
Compare the expected repair work with the cost of a suitable replacement, including labour and any additional work needed to fit it. Don’t judge by the part price alone: diagnosis, access and the condition of the shut-off valves or connections can affect the job. If a professional recommends replacing the faucet, ask what is damaged or unavailable and whether a targeted repair is still feasible. That gives you a reasoned basis for deciding rather than replacing a fixture simply because it drips.
A continuing drip can point to a worn washer, cartridge, seal or another part of the valve mechanism. A small amount of water draining briefly from the spout may not mean the faucet is still leaking; dry the outlet and check whether fresh drops continue to form.
Often, yes, if the problem is a replaceable internal part and the faucet itself is in good condition. First identify the faucet type and source of the leak, then confirm that the correct replacement component is available.
A small spout drip may not prevent normal use, but leaks around the handle, base or under-sink connections can wet cabinets and conceal a worsening problem. Check the area regularly and stop using the faucet if water is spreading, the leak is difficult to contain or nearby electrical equipment could get wet.
The cartridge may be the wrong model, incorrectly oriented or not fully seated. The leak may also come from a damaged sealing surface, a different seal or a connection that was disturbed during reassembly. Shut off the water and recheck the manufacturer’s instructions; if the cause remains unclear, arrange an inspection.
Check the tenancy agreement and ask the landlord or property manager before dismantling or replacing a fixture. You can report the leak promptly and provide details or photographs, but responsibility for the repair depends on the arrangement and applicable local requirements.
For effective leaking tap repair, locate the leak before choosing a part or replacing the fixture. If the cause and compatible component are clear, a careful repair may be enough; if they aren’t, a handyman or plumber can diagnose the problem and explain the practical options.
