There is a special orange pvc pipe that you buy by the foot for natural gas.
It uses metal connectors on the ends. Gas companies use it. I used black
pipe on the ends and coated them with tar on the parts near the ground. I
had put pvc white drainage pipe in floor etc to make my hole. Water line
can be run with continuous black pvc pipe.
I have phone, water, gas, and electric lines running underground from house
to garage.
Please check out with experts and code personnel in your area.
