I want to tuck the main gas line coming into my house up into the floor joists so I can finish my basement/ceiling. This is purely for aesthetics. However, the builder never put in a coupling anywhere in the line. I am only a few feet inside the house from the meter (as far as where I need to make alterations to tuck pipe). A friend says that I will have to begin at the meter and start taking things apart until I get to where I need to be. Problem, we are in the middle of a cold snowy winter. My question is this: is a builder / contractor required to put one or more couplings in line for future repair work? or is this purely courtesy?
