Does your 20 inch height toilet flush well?
Actually, better than most siphonic toilets – and here is why. Our super tall bowl elevation adds some more power to the siphonic flush, based on height and gravity physics; all contents rush downward drain moving incoming water at naturally an increasing speed. Convenient Height 20″ toilets have the advantage of added steeper elevation which is naturally very good for a stronger siphonic action. Right after the trap way bend, the route is downward all the way into the drain, with literally no resistance at all. The Convenient Height Co. production plant tested Model S toilet with 3 ping pong tennis balls and additional hard items in the bowl at the same time and it flushed very well; additionally, it passed the 800g/1.7lbs. hard artificial waste flush testing.
DUAL FLUSH OPTION: up for half of flush, down for full flush
