How do I fix a leaky faucet or tap on my own?
A dripping faucet is one of the most common household plumbing issues, usually caused by worn internal parts such as washers, O-rings, cartridges, or valve seats. Before attempting any repair, always turn off the water supply valves under the sink and open the faucet to drain residual water. The repair approach depends on your faucet type.
Faucet Types
Compression faucets use rubber washers that wear out over time. Ball faucets have a rotating ball mechanism with spring-loaded seals. Cartridge faucets use a movable cartridge to control flow. Ceramic disc faucets rely on two ceramic discs that slide against each other.
Diagnosis
Identify where the leak occurs: from the spout (usually a worn washer, O-ring, or cartridge), from the handle base (often a loose packing nut), or from the faucet body (possibly a damaged valve seat). Each location points to a different repair.
General Approach
Disassemble the handle carefully, inspect internal components for wear or damage, replace the faulty part with an exact match, and reassemble. Take old parts to a hardware store to find correct replacements.
- Replace Washer or O-Ring4
The most common fix for a dripping faucet, especially compression and cartridge types. A worn washer or O-ring no longer forms a watertight seal, allowing water to seep through even when the handle is fully closed.

- Clean or Resurface Valve Seat3
If replacing the washer does not stop the drip, the valve seat is likely the problem. The valve seat is the metal surface inside the faucet body where the washer presses to create a seal. Over time, mineral deposits or corrosion pit this surface, preventing a tight seal.

- Tighten Packing Nut or Adjusting Ring2
When water leaks around the handle base while the faucet is running, the packing nut or adjusting ring is likely loose. This is a quick fix that requires no replacement parts in most cases.
