What will happen if underwear gets flushed down the toilet?

Answer 1

It will flush!

Commercial toilets were always designed with the pressure to readily dispose of articles like these typically dropped into a toilet, they can handle them without hesitation. Today's household toilets often have phrases like 'no clog' on the box indicating they also have more than enough suction to handle and successfully dispose of underwear in a single flush. Once flushed, it will rarely require a second flush to finish them off. So, if you drop a brief, intentionally or not into a flushing toilet, don't expect to see it again. These toilets are designed to expel them out into the sewer lines in seconds where the pipe diameter moves up to eight inches (or more). From there, they're on their way to a waste processing plant. I have two sons and the older walked in on the younger (at the time too young to know any better) who was dropping his older brother's white socks and Jockey briefs into a flushing toilet in their bathroom. There was a pile of unfolded 'whites' of his older brother's atop the counter and the little guy decided to 'clean things up.' By the time the owner walked in, there was little left of the stack. There was a week's worth of his underwear missing....evidently flushed down the toilet. The boy's have an American Standard 'Champion' toilet upstairs and it evidently had no problem doing away with half my Son's undies in one session!
