I am trying to hook up a 40# LP tank to my house to supply my gas stove. I have the LP conversion kit installed and piping installed and inspected to the the exterior. Can I just use flexible piping (i.e. Mr Heater type/gas grill) and connect it from the house termination to the tank?
The gas grill lines aren't OK but CSST, which is a flexible line usually painted yellow for interior or black plastic coating for exterior, should be OK. Here is a safety website about CSST http://www.csstsafety.com/
