The answer to 'my drain is leaking' is that a leaking drain is a common plumbing issue that can have several potential causes. Some common causes include a cracked or damaged drain pipe, a loose connection, or a clogged drain. Symptoms may include water pooling around the drain, water stains on the floor or walls, and potentially a musty odor.
The solution will depend on the specific cause of the leak. For minor issues like a loose connection, you may be able to tighten the fittings or use plumber's putty to seal the leak. For more significant problems like a cracked pipe, you'll likely need to replace the damaged section. In some cases, the issue may be deeper in the plumbing system and require more extensive repairs.
