toto drake - good at flushing, chain always coming loose
I bought 2 drakes for my home and they certainly are good at flushing, they never once got clogged where my other toilets, gerbers, were always getting clogged. I only issue I've had with them is the link that connects the chain to the flap was always coming off, so I would have to open up the tank and re-attach. This happened to both the toilets, so I'd have to say that this is a flaw in the manufacturing of the toilet.
Korky 3" Replacement flappers for the Drake are carried at Lowes for $9.99
Another Drake, and a question
I just replaced an 11-year-old American Standard Pressure-assisted Cadet with our 2nd Toto Drake. Main reason was that we were getting used to the ADA height on our first Drake, and plopping down on the old standard-height Cadet wasn't fun any more. A few days later we're a very satisfied 2-Drake family. Sold the old Cadet for $10 at a local used building supplies exchange.
The question: as I inspected things prior to installation, I noted that at the trapway exit, there's a deep ridge in the interior of the trapway circumference, about 1/4" above the exit. I'm wondering why this wouldn't be a potential point for a snag and clog to develop? I don't remember seeing this in the first Drake, but then again I didn't look it over very carefully. Seems to me I'd want this to be a smooth surface to encourage the waste on its way.
