|Brand X. Notice the tight bend in the goose-neck curves around more than 180 degrees.
Picture if you will, logs racing down a stream.
Do the logs get jammed up in the straight-aways or the long gentle bends.
No, they get jammed up in the tight curves that bend back on themselves.
The earliest low-volume toilets simply took the 3.5 gallon-per-flush geometry and scaled it down. That meant that the inside curves were that much tighter.
The second generation replicated the 3.5 gallon-per-flush geometry except they used the same inside radii for the goose-neck rather than scaling down.
|An Eljer toilet as recommended by The Freeholder. Notice that the tightest part of the goose-neck is not as tight as the toilet in the first image and it is not a full 180 degrees.
Then somebody had the brilliant thought, "Since we know tight bends are an issue, why don't we design a goose-neck and trap that minimizes those bends?"
Mrs ERJ suggested we spent the little bit extra and buy the toilet The Freeholder recommended.
Being retired is a bit like being a toddler: Go, go, go, go, nap. "Hey, where is my bottle?"
