[Greenbuilding] Toilets that Work

[Reuben Deumling]

It seems we are talking about at least three different categories when it
comes to toilets that are water misers:

(1) flush toilets that look, feel, and operate more or less like the
standard toilet;
(2) flush toilets that may have additional hardware (vacuum, foot pumps,
urine diversion);
(3) dry or composting toilets with or without urine diversion.

List participants have shared very helpful and encouraging stories of their
experience designing and living with inexpensive toilets in category (3).
Several of us seem to enjoy thinking of ways to modify toilets that would
probably end up in category (2). But since we've come up with several
avenues for identifying toilets in category (1) I'd like to see how far we
can go with this one. Many of the folks I encounter would I think be tempted
by such a toilet.

My Suggestion:
(a) Identify toilets that use less than 0.8 gpf, whether by throttling a
high performer from the CWWA/MaP list or because someone has designed a
toilet to do this, or via some route we haven't thought of & extra points
for the lowest gpf;
(b) Identify toilets that do this for <$250

My favorite contender so far is Lawrence's American Std. Cadet 3 for $130.
Does anyone have one they'd be willing to experiment with? What are barriers
to throttling this by say 60%? Tank mechanics? Flushing performance? Other?
