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?

We have three Kohlers at work and they have been fine. No backups at all.
Get the elongated model for comfort.
