Anywho - great fan of plastic now.

Until the ceiling comes down.

That only happens

Matt, this is not for your info, it is for the OP, as you are lost case.


I'm the OP.

Actually, I wasn't asking for comments on whether plastic pipe and / or
push-fit fittings are a good idea.

( I'm satisfied enough that they are. )

I was wanting to know what king of insert to use with a compression fitting,
because I didn't know if the insert was related to the pipe, or the fitting.
