I've had to replace the bottom entry filler system on my WC and i have a
very slight drip which is coming from where the copper nut fixes onto
the threaded plastic inlet pipe.

I used some silastomer sealing compound when I had a minor leak from the threads
surrounding the pipe to the WC. Has the advantage that it sets under water, and
it's been leak-free for many years now.
