We just installed a new TOTO C744E toilet bowl with a new ST743E toilet tank. It was leaking very slightly on the right side ( a very slow drip--nothing that would wet through a hand towel even after two days) coming out of the right side tank bolt area (no wetness on the left side of tank). The plumber came back and readjusted the bolts making sure they were tight and secure...still the leak--ever so slight continued. After a week we ordered a new tank thinking there surely must have been a leak somewhere around the tank bolt hole area. BUT, we are having the same exact issue with the replacement tank. Could it be the tank-to-bowl gasket is not seating properly between the CST744e bowl and the ST743e tank? Is there a 744e tank we should be getting? When we checked online for the proper tank to go with our bowl it recommended the version we purchased; which was the ST743E.
Any suggestions? Thanks in advance for any help with this issue.
