I probably do as the pressure gets the water up to the 3rd floor with
no problems. Center city Philadelphia. I guess it is ok. How about
this Gerber, worth trying?
Why do you need pressure-assist if you have adequate pressure? The
noise from some pressure-assisted toilets is quite loud.
Toto has probably the best toilet reputation. I find even their low
volume tank toilets work just fine.
Not unless you're referring to those $3,000 computerized toilets that
are common in Japan.
Here's Consumer Reports' 8/2009 evaluation:
Out of 19 single-flush units tested, the best Toto ranked #9 (great
for flushing solids, average for liquids), the other Toto, #15 (great
for solids, awful for liquids).
The top 8 flushed both solids and liquids great:
American Standard Champion 4 2002.014
Kohler The Complete Solution Cimarr๓n K-n456
Kohler Highline Comfort Height K-3493
Gerber Avalanche 21-817
Gerber Ultra Flush 21-318
American Standard Flowise Cadet 3 2403.128
Gerber Ultra Flush 21-302
8 American Standard Cadet 2366.100
Also the #13 ranked toilet flushed just as well as the best, and like
its #6 cousin it used only 1.28 gallons per flush:
American Standard FloWise Cadet 3 2835.128
However both of those American Standard FloWise Cadet 3 toilets were
only average at cleaning the bowl, while all the others mentioned
above, including the Totos, were above average in that respect.
In our city every house has water meter, pressure gauge and regulator.
Our house has static 60PSI typical.
Look around the neighborhood for the water tower supplying your street. Most
water distribution systems depends on gravity for the resulting pressure.
The formula is 0.433 x height of tower = p.s.i. A tape measure, angle
deducer, and trigonometry will easily give up the height of the tower.
So a water tank of 115 feet will yield a water pressure of 50 psi at street
level. Assuming you have such a tower in your neighborhood, on the third
floor, you'll have to subtract 25' of head (2.5 stories x 10' each). That
(115 - 25) x 0.433 = 39 psi.
Alternatively, for the third floor, subtract about 11 psi from the street
level pressure (25 x 0.433).
