in little under three hours i became certified as an installer of natural gas piping, along with revolutionary plastic PEX potable water piping. this means anywhere in the country i’m licensed to purchased these specialty equipment. it’s rather scary that anyone can take the seminar and walk out with a license. now i can “rewire” the natural gas lines for greater efficiency and appliance servicability. remember these little events called earthquakes in CA? with flexible water and natural gas lines, it less likely that they would blow up, or punch through a wall. i’ll let you know when i draw my first 10 meters of tubing next time.
