Gentlemen,
I have a Toto Drake CST744s. It's a couple of years old, now. We have serious water issues at my condos. The water puts out a lot of minerals and our water lines have calcium build-up. Recently, my toilet started giving me the once-per hour hiss that seems to be the symptom of a bad flapper. I ran my finger along the flapper and flush valve lip to remove any crud. However, I found a gelatin type goo there. It all came off with my finger, but the once-per hour hiss remains. Grrr. Online a lot of people are complaining about the Toto 3" flappers. Is there something wrong with the design? Is there any mod that I can do to get better life than two years out of a flapper? A Toto-Korky genuine flapper costs $25. That's insane. I did see that Korky says that the part number that replaces the THU175s is the THU331s, and that they sell it in a non-Toto number of 2021. Home Depot sells a 2021cm. EBay has a bunch of 2021bp available for $10. They say they are for 3" Toto G-Max. So, what gives with the letters? Is it a bunch of hooey and doesn't matter?
Thanks for any help.
