“Instead of one flush with the old 3.5 gallon tank,”
True story, once I sat on a circa 1955 soviet toilet seat. When I flushed, it literally went off like a Martin Baker rocket powered ejection seat. It startled me. It nearly sucked me in. Something roughly like 200 gallons of water shot through it in about 1.5 seconds. The sound was freaking amazing. The Dnieper river was nearby and it appears water use was not an engineering parameter.
The locals also used it the way we would use a garbage disposal in the kitchen sink.
I wish I had one here, but it would be too embarrassing for neighbors 3 houses away to know every time I was on the throne.
Now that’s a royal flush ;)
