Hi All,
I'm trying to perform a repair to a hydronic heating system (carpenter put a nail thru a pipe).
Pipe is 3/4" Uponor hePEX and has been installed for about 10 years.
For the fix, I cut out section of pipe which contained the hole and added new pipe section and two couplers. Now, there is a very slight leak where the new ProPEX EP couplers connect to the old pipe (both ends are leaking). I was careful to rotate the manual expander tool between each expand...
My only thought is that there is build up on the inside of the hePEX that is causing a bad connection with the coupler. Does this sound plausible?
Before I go back and try the fix again, I thought I should get some feedback. Do you think cleaning the inside of the pipe with a soft brush (toothbrush?) would do the trick? Any other ideas?
I guess another option would be to use push fittings. And of course, this connection is buried behind drywall.
This is the 1st time I've ever seen an Uponor fitting leak!
Thanks!

p.s. another issue I encountered (for the 1st time) was that the rings were sliding up the pipe (past the stop) when using the expander tool. I was able to make this work by lightly sanding the outside of the pipe which caused the ring not to slip.
