If you've tried using a plunger or drain cleaner and the problem persists, it's usually a good idea to call a plumber.
Here are some other indicators that it's time to call a professional plumber:
Unpleasant sewer odors: If you notice unpleasant sewer odors coming from your drains, this could be an indication of a clogged sewer line.
Gurgling sounds: If you hear gurgling sounds coming from your drains, this could be due to air bubbles attempting to escape from a clog.
Slow drainage: Water draining slowly from your sink, shower, or bathtub could indicate a clogged drain.
Several clogged drains: If you have more than one clogged drain in your home, it could be a sign of a larger problem, such as a clogged main sewer line.
If you notice any of these symptoms, you should contact a professional plumber to inspect and clear the clog. Attempting to clear the clog on your own may result in additional damage and more expensive repairs.
