As a homeowner, you’re sure to deal with clogged toilets, leaky pipes and other plumbing situations every once in a while, but multiple drains all backed up at the same time is a different story. Chances are, your main sewer line is already clogged. Water has no place to go so it goes back up and out of plumbing outlets. Here are the signs:
The sink. Run the sink nearest the toilet for a minute. Is the toilet water rising? Are there bubbles forming? This is one indicator that there’s air trapped in your sewer system, which is most likely caused by a clog.
The toilet. Flush the toilet. Is there water backing up and gurgling in the tub or shower? If yes, this means the flushed water is trying to flow down the pipes but is blocked by the clog so it goes back up to the lowest point, which is usually the shower drain.
The laundry. Run the washing machine. If draining the water is followed by a backup in the toilet or tub, it could be due to a sewer drain clog. However, if the toilet is flushing fine, the problem could just be limited to the washing machine and/or shower drain.
If you suspect a main sewer clog, first, look for the water shut off valve to cut the water supply to your home. Then, ensure that the drain is cleared as quickly as possible by calling an emergency plumber.
