Many areas have rebates available for switching to a low flow toilet. Check
with your municipality or water company. If a rebate is available you might
as well pick from one of the approved models, if there is a specific list,
or ensure you pick one that meets the listed specifications.

I need to replace the toilet in an upstairs, second story bathroom. I'd
like to get a low-flow tank to save water but I don't want to end up
with one that won't have enough water pressure to properly flush without
clogging all the time. Is there any kind of minimum gallons per flush
or anything else like that I should be looking for?

Google this group for "Toto" and/or "Toto Drake". Enjoy.
