There are a couple of indicators that you might have a sewer line issue:
- Frequent Drain Backups: if you are experiencing drain backups then you should use a liquid drain cleaner to unclog your drain. Otherwise, if the blockage is more severe then it is recommended to call a professional before the blockage gets worse.
- More one one plumbing fixture is clogged: if multiple plumbing fixtures are experiencing backup then your main sewer line is luckily to have a blockage.
- Strange reaction from plumbing fixtures: if you are experiencing any unusual reactions such as a gurgling noise coming from your toilet or bubbling toilet water, then you should contact a professional to assist you with unclogging your sewer drain.
