Getting ready to purchase 4 toilets for our new house build. I've narrowed my choice down to either the American Standard Champion Pro or the Cadet Pro from a plumbing supply store. Comfort height, elongated bowl. I saw in another thread that Terry recommended the Cadet Pro over the Champion, and I'm trying to figure out why. The Champion Pro has a 2-3/8" trapway vs. 2-1/8" in the Cadet Pro. Champion Pro has a 10 year warranty vs. 5 year for Cadet Pro. 3" flapper valve in the Cadet Pro vs. 4" accelerator flush valve. Being in Oregon, we're limited to 1.28 gal flush. I figure I can change out the flush valve to the 1.6 gal part if needed in the Champion.
