help1. Understand the Problem

A faucet that drips after being turned off typically indicates a worn internal seal, such as a cartridge or O-ring. Over time, mineral buildup or rubber degradation prevents a watertight seal, allowing water to seep through. This issue is common in compression and cartridge-style faucets.
