: I would like to bring gas supply to my pool heater (200 000 BTU). The gas meter is on the opposite side of the house. Assuming that I can go through my basement, can I enter and exit the basement though the "joists", or does it have to go through the concrete foundation? Once out of the basement on the other side, how deep do I have to trench it to the heater? What materials are typically used? Cant I send a supply (T) off to an outdoor gas grill as well?
