Thanks for taking the time to share your feedback with us, Janelle. Charmin is not expected to cause any problems in properly functioning plumbing and septic systems. We’ve worked with the Master plumbers from Roto-Rooter, the number one plumbing company, and they agree that while some backups can occur in the toilet itself if too much paper is flushed at once, the most common cause of pipe and sewer clogs is something in a drainpipe or sewer pipe that doesn't belong. Other factors, such as the age of a toilet, can also affect its performance. The internal parts in the tank begin to wear out after only a few years and may need to be replaced to restore strong flush performance. Additionally, low water pressure may also be the culprit for a weak-flushing toilet. We're happy to help more and encourage you to give us a call at (800) 777-1410.
