[Superman] Could the sheer force of Superman's stream of piss break a toilet?

If Superman were to take a piss at full force, could he break a toilet with it?

Trivially. He could let loose at a urinal in the 10th floor lavatory of an office building, aiming exactly straight down (he may need to hover for the right angle). That stream's leading plane would shear straight through the porcelain coating, through the metal, back out the other porcelain side, through the floor layers, through the next nine levels of urinals and floors, continue through the eight levels of concrete reinforced parking garages underneath, and then keep punching down into the Earth below. Eventually it would bleed off sufficient kinetic energy that it simply became a little puddle of pee that got diffused into the soil. 

Elapsed time for all this: microseconds, *if* that. 

Here's the trick: *every* aspect of him is Super, including his bladder and velocity control, so if Supes was peeing next to you at the urinal (spoiler: he probably hasn't *had* to #1 or #2 since he was a little kid), you'd never know he was anything else besides a 6'3" massive alien dude in tights at the next urinal over from you, who makes great small talk as you wash your hands, takes a selfie with you after in the hallway, and for thirty seconds before he flies off, makes you feel like the most important person in the galaxy.
