- Drains are Clogged Clogs happen. Too much hair clogs up your shower drain or maybe someone tried to flush something they shouldn’t have. But in the case of a mainline sewer problem, you’ll find clogs happening all over the house simultaneously. A major symptom is if you see clogs and water backup starts to happen in drains you don’t frequently use, like a basement sink.
- Toilet Problems If the toilets in your home are having flushing issues, and a good plunging doesn’t solve it, you may have a larger problem. Flushing issues in more than just one toilet in your home is one of the biggest signs of a problem with the mainline. If you begin to see this, call a professional plumber immediately. Toilet issues aren’t something you want to let sit. You may also notice unpleasant odors around plumbing fixtures in your home.
- Odd Water Backup Did your shower drain start to bubble and gurgle when you used your toilet? Did your kitchen sink back up a bit when you did laundry? That’s not good. Water will find a way out, so if it is stopped by a clog in one pipe, it will try to get out through another source.
