I looked up my original question on the net and the below info was the
best answer I could find:
Not all compression fittings are suitable for connection to plastic
pipe. Compression fittings with a short pipe stop depth or hard olives
should not be used with plastic pipe.
Use a TSM Insert described in answer 1. This will enable the pipe to
withstand the compressive pressure of the olive. Push the pipe with
the insert up to the pipe stop within the fitting. The olive must be
located along the length of pipe supported by the pipe insert. Hand
tighten the compression nut then tighten the nut with a spanner approx
one more turn. Softer copper olives are preferable to brass olives.
So, it doesn't say you have to use Plastic Compression fittings on
plastic pipe just "...softer copper olives.." So, does anyone have any
experience with using meta on plastic pipe? I have no idea if the
"Olives" I have are either HARD or have a "short pipe stop depth." The
article only states that copper is PREFERABLE to brass. Also, can
you reuse the TSM Insert? No doubt they are only a buck or so for a
couple but I have a leak right now in my plastic pipe and all I have
are brass? olives and a used TSM. Also, is their any kind of prep
work I need to do to the pipe prior to making the joining?
My problem is the pipe providing water to my icemaker developed a
small pin leak - well, big enough to make a mess. I cannot belive
they just happen but apparently I can't blame this on my kids. Tracing
the plastic pipe to the source I found there is no way to turn the
water off - this was pretty much a given considering my luck. IS
THERE A VALVE I CAN INSTALL TO TURN IT OFF? I'm not sure if they
have them this small but it would be nice to be able to turn off just
this water rather then the house supply. I crimped the plastic pipe
with a pair of pliers just behind the leak rather then cut of the main
water supply. Seems to be working. But I wanted to see if I could
fix this tonight rather then waiting.
If I do go to the store, do I get a METAL TSM INSERT ( that is what is
there now ) or do I use a plastic insert - if they make them.
BUT, My bigger concern is that I'll do some kind of haphazrd job that
will find me coming home one day to a foot of water in my home. This
seems like it could happen at any time with that plastic pipe but I
don't want it to be my fault.
