I will be installing quite a bit of copper tubing. Probably a 60' run of
3/8" hi-pressure run and several normal pressure 1/2" runs in the
neighborhood of 50-75 feet and possibly a 3/4" run of 25 feet or so (large
tankless water heater).
Wondering if there is a lower cost do-it-yourself alternative to copper
tubing. I installed underground plastic tube supplied by LPG dealer and they
came out to install the fittings and terminate it to the tank and regulator.
They way I get it the plastic fitting is a proprietary system that requires
some special connectors, tools and training. Even if this stuff was adequate
for indoors use, by the time I paid for the tube, fittings and the service
man to install all the connectors I'm back at the price of copper.


I used black pipe for a similar project. Cutting/threading is easy when
using those sizes.
