These have to be an old acorn engineering stainless steel toilet because those are awfully loud but a dope flush but the newer ones are a slightly quieter and the trap way are smaller
Random Stuff In Oregon I honestly thought when i first saw one of these (floor mount) that it was just a STRAIGHT SHOT down into the drain pipe (the bowl would be }{filled bc a valve/flap would be on the end of the toilet’s pipe and before the drain pipe), and on the wall hung one’s it would just be a 90* curve and a STRAIGHT SHOT into the drain pipe
