yeah I have never had a plastic line fail although I was warned they
can, but being much more flexible than copper its been great for me.
the ONLY trouble I EVER had was installing a ice maker line for a
friend. it went fine, I then started fixing the stove, and found I
needed parts. Just before I left I went downstatairs to check for leaks
and was shocked to find the plastic line had blown off the sadle valve
fitting and was spraying water all over the basement cieling ....
I cut the entire fitting off and stopped at the hardware store
they said oh the ferrule for a plastic line MUST be plastic, your kit
had the wrongf part.
70 cent fix, has worked fine ever since.
