If there is an unusual or unexpected reaction when the plumbing is used, there may be a drain problem. The drain is clogged if water backs up into the tub or shower or when the toilet is flushed. If flush water cannot enter the main drain, expect it to appear at the lowest point, which is the tub or shower. If you can confirm a main sewer clog, contact Plumbing professionals they have the right tools and equipment.
