help1. Understand the Problem

A dripping faucet spout is most often caused by a worn or damaged cartridge inside the handle assembly. Over time, mineral deposits and debris can also prevent the cartridge from sealing properly, allowing water to leak past. This issue is common in both single-handle and two-handle faucets.
