If your toilet is constantly clogging, or you are experiencing backflow this is likely due to excessive grease, tree roots, paper towels being flushed, or other large items that have gotten stuck in your sewer lines. With a Professional Camera Inspection, your Pronto plumber will be able to identify exactly what is clogging your sewage lines so you can then tackle removing it next.
