The answer to 'drain leaking water' is that a leaking drain is a common plumbing issue that can have several possible causes, such as a clogged drain, a faulty seal, or a damaged pipe. The symptoms may include water pooling around the drain, water stains on the floor or wall, and a musty odor.
Some potential solutions include using a plunger or drain snake to clear a clogged drain, replacing a worn-out seal, or repairing or replacing the damaged pipe. However, if the issue is more complex or you're not comfortable tackling it yourself, it's best to call a professional plumber to diagnose and fix the problem.
