Good Housekeeping Institute
For a quieter option, pick the gravity-fed, dual-flush Toto Aquia ($395). It has an extra-low 0.9-GPF small flush for liquid waste, and its 1.6-gallon full flush was tops in the Good Housekeeping Research Institute's clog tests.
(It's one we like to sell too, very dependable in use, of the 115 that we have sold, we haven't had to do any repairs) Terry)
i cannot tell you how grateful i am for your site and your advice! i have consulted it many times as we've planned this remodel.
we're currently building basically from scratch a gutted bathroom. we wanted a watersense-compliant toilet that looks good, preferably dual flush, and not one of the taller-than-usual models. we narrowed it down and gave preference to ones we could find locally here in pittsburgh, because we'd ordered TWO caroma caravelles online and neither reached us (ups, damaged in transit, yadda yadda). we eliminated the kohler because we heard a lot of stories about leaking and difficulty in getting parts (!). so that left us with the aquia I and II. but i can't figure out what the difference is. would you mind illuminating this for us?
thank you again so much!
