Hi everyone, if this has been discussed before I apologize. I did a search but couldn't find my answer. I have four toto drakes that are 6 years old. I had bought flapper replacements as a back up and they were Thu138s. I can't find those and sites are saying it's now part Thu331s. I emailed Toto and she said it was now part Thu347s, but this one is gray and my original and replacements are red. I tried following up two more times but Toto is not responding anymore. Inside my tank it does say it's number Thu277s which now is the Thu347s Toto mentioned. So my question is what's the difference between the thu331s and the thu347s? Will they both fit? I just replaced a flapper with my last thu138s and it fits fine. I've also noticed that I have one brass lever rod and the rest plastic. Two have the black float/weight on the chain and the other two don't. All these toilets were bought at the same time and installed when the house was being built. Why doesn't everything match? Thanks
Jay
