Today removed the tank and replaced all internals as well as seals and bolts to the bowl. When snugging tank back to to bowl, heard a disturbing "crack" sound.
All elements are working well after the rebuild, but there is a very slow leak coming from area of tank/bowl junction. Checked all other fittings - no leaks there and it appears to not be at the seal between tank and bowl - but dripping from bottom end of both threaded connecting bolts.
I'm going to take it apart again this evening and expect to find small cracks at and adjoining the bolt holes at bottom of tank - where the rubber washers normally seal. If that is the problem, has anyone been able to dry/clean/abrade and then use a proper epoxy cement to fix such cracks and stop the leaking?
Or, am I going to go buy a new toilet? Thanks for any help.
