I too use regular toilet paper, Charmin Extra Strong. Have never had a problem. However, about a year a go I attempted to throw a Makeup Wipe into the trashcan. Unfortunately it landed in the toilet. I foolishly decided to flush the Wipe rather than fish it out. That was a $400 bad decision. When they say NEVER put anything but toilet paper and bodily discharge into a toilet, THAT'S GOSPEL!
