I would start off by saying that this toilet is one of the best modern commercial toilet ever seen, even for now! The flush is great nevertheless the irritating noise, the same goes to bowl rinse, design, trapway passages, etc. Absolutely astonishing and deserves mythical reward of plumbing name! I’ve seen no problem with this thing as not encountering one that did clog. Don’t get me wrong, I don’t know why other people thought this has “so much drawbacks” though…
These Sloans are just Flushometer versions of Glacier Bay... My workplace has these guys installed, went later the day to take a leak only to find a nasty surprise in one of these... Decided to flush them and they clogged because of shitty trapway design.
