Aloha,
I recently purchased a Toto C744EF.10-01 bowl with the ST743S-01 tank and was wondering if the fill valve should squeak when it shuts off. I originally purchased a C744E-01 bowl and ST743S-01 tank but I returned the bowl because it had something clanking inside of it. I decided to get the 10" rough in one instead and used the same tank (wife isn't pleased with the 1 1/2" height difference LOL). I am also have a problem seating the tank to bowl on the three high points on the bowl. I am left with about a 1/4" spaced evenly between tank and bowl so the tanks moves when flushed. Is there a slightly thinner tank to bowl gasket?

Mahalo,
