The answer to 'bathtub not working' is that there are several common causes, including a clogged drain, a broken stopper, or a problem with the plumbing. Symptoms may include the bathtub not draining properly, water not filling the tub, or the faucet not working correctly.
Some potential solutions homeowners can try include using a plunger or drain snake to clear a clogged drain, replacing a broken stopper, or checking the faucet and plumbing connections. However, if the issue is more complex, it's best to call a professional plumber to diagnose and fix the problem.
