The Toto Drake was installed 11/2005 even though the plumber thought it might be hard to get repair parts. Not one clog in 8 months. The American Standard 3.5 gal it replaced would need the plunger at least once a week. We are replacing the other 2 toilets with Toto drakes next week. The plumber is still trying to talk us into the new American Standard toilets, but 8 months trouble free made the choice of Toto the right one for us.
Thanks for the helpful reviews.
