The answer to a bathtub overflowing is that it is typically caused by a clogged drain or a problem with the overflow drain. Symptoms include water spilling over the tub's edge, a slow draining tub, or gurgling noises from the drain.
Some common solutions for an overflowing bathtub include using a plunger or drain snake to clear the clog, checking the overflow drain for blockages, and ensuring the stopper is functioning properly. If the problem persists, it's best to call a professional plumber, as they can properly diagnose and fix the issue.
