I use propane for cooking (gas range - oven & stovetop) ONLY. The copper wire is kinked & needs replacement. The propane tank is NOT hooked up right now. This seems like a simple project (could be famous last words.) Do I need to just get some propane piping of the same diameter as the current copper & string it thru as I remove the copper? I'd prefer flexible piping because copper kinks so easily. The propane company will come hook up the tank, inspect the lines/regulators and hook up the range once I'm through. I'm very handy (landlord for a long time) and they're not available until next week to replace the lines. Any thoughts on this project? Am I missing anything? THANKS!!
