Heater installed by HVAC certified company. Tee left to run gas to one downstairs kitchen, and upstairs kitchen needs a line too. What is recommended for ease of install, and inside or outside of wall? I have done black pipe for years, lot's of turns etc, but I can do it. Disabled and don't want to hire a plumber, what are my options?
I was a potter, and built many kilns!
Is the yellow flex tubing legal for an individual to install-Portland , Oregon?
Are you talking about a product like trac pipe. If so every manufacturer I know of won't sell it to you without a certification from the manufacturer. Your plumbing supplier will give you a test, mine will let you take it open book. Hope this helps.
