What is the most common cause of a leaking tap?

In Perth homes, the most common cause of a leaking tap we see is a worn or damaged washer (or seal). Over time, constant use and water pressure cause these components to wear out, preventing the tap from sealing properly. Perth’s hard, mineral-rich water can also speed up this process, leading to earlier wear and ongoing dripping. In newer taps, the issue is often a worn ceramic cartridge rather than a traditional washer.
