I've been getting numerous versions of what is required for the buried gas piping to connect my outdoor gas water heater for a pool.
The UPC codes I've seen on-line say >18" depth and lists various materials allowable for the pipe. However, one of the quotes I've gotten included a separate trench (the electrical is still open at >18" depth) because gas piping must be flat, and can't follow the ground contour. This obviously is not something I want to do (pay for), if not needed.
Also, is copper tubing acceptable, assuming the right OD and type, for buried installations??
