My toilet has started leaking from the fill line in the back. It's the pipe that is screwed into the toilet that is leaking and it is a messed up situation. The pipe is the gray flexible pvc directly attached to the shut-off which is then directly attached to toilet fill port. By directly I mean the gray pipe has been crimped directly to both sides of fill valve. My question is are were there 2 different wall thinkness' of the flexible gray pvc pipe. I only ask because the hardware store guy said that at some point the flexible gray pvc began to be manufactured again but with a different wall thickness because entirely different manufacturer. I find this hard to believe but before I make an irreversible cut into my toilet fill line I want to be absolutely certain the hardware store clerk was talking out his ass.
