Hello all. A (hopefully simple) question regarding the half inch plastic water lines. We have a very tiny leak at the connection behind our toilet (OEM). I'm pretty sure it is the flanged end of the plastic line that comes out of the wall just behind the toilet. The flange is badly gouged from somebody overtightening from the PO I believe. I've tried adding a washer and other things, but cannot seem to get it to stop.

I see that they make a compression fitting that looks like it will work with the gray plastic line, but before I cut off the old flanged end I wanted to verify that I'm doing the right thing. The fitting like these looks like it will take the raw gray tubing.

Just wanted to make sure, am I correct in assuming that if I cut off the factory flanged end that I can use a compression fitting like above (just the nut piece) to re-connect it?

Thank you!!

Chris
