Over the years the threads on using PVC vs black pipe have been of
minor interest to me as, 'one day' , I intended to put lines in the
shop.

Yesterday I spent the day putting in 5 outlets. The piping was
polyethlene with polypropylene fittings. Connection was very easy, cut
with SCMS and tighten nut by hand - that's it.

At the end of the day I ran it up to 150PSI and didn't get a hint of a
leak. One of the things that attracted me to this setup was the fact
that if I move house I simply unscrew the system by hand and take it
with me.

Cost: US$290 for 65' of 1" pipe, 4 Ts, 4 elbows, 5 stop cocks,
associated fitting connectors and mounting saddles.

I'm looking forward to a shop free of snaking hoses.
