Is this correct?
A Toto Drake tank properly filled has about 3 gallons of water. If you push down the handle till it stops and promptly let it go (Toto calls it a "full stroke".) then a 1.6 gallon flush takes place. That means that you still have about 1.5 gallons left in the tank just in case you need a second flush...a full 1.5 gallon, no wait flush. This second flush could be needed not to flush "bulk" but as a bowl wash.
The details and coaching you get on these forums are invaluable!
I'm searching for an excuse to go get an Eco Drake Elongated ADA or an Eco Elongated ADA Ultramax to replace my old 3.5 gpf perfectly good toilet.
Since water is plentiful and prices are low, it would take about 14 years to get payback on an Eco Drake ADA Elon.
