Hello,

I am about to make my first attempt at plumbing with plastic pipe. I
am a bit confused about what fittings to use. I know to use the
correct Pb or PEX inserts.

I know I can use standard brass compression fittings and some of the
push fit for copper fittings say you can use them on plastic pipe too,
but I see there are also plastic push fit fittings: are these just to
join plastic to plastic or can they be used to join plastic to copper?

What is the best to use: compression? Are we still paranoid about push
fit?

TIA
