Just installed a new cast iron porcelain sink. For the life of me, I cannot
get the drains to stop leaking. They are only leaking a tiny bit, but of
course, that's not good. I used plumbers putty fairly liberally when putting
the drains in, and tightened the hell out of them. However, I'm getting the
suspicion that putty might not be the best thing on porcelain.
Would silicone be better? Or is there some other trick I'm not aware of for
porcelain (in other words, the putty worked fine when I put in my bathtub,
which is plastic/acrylic/whatever).
Thank you in advance.
