I am running a 1 1/4 gas line to the garage in the rear of my lot - total run is about 85 feet. Trench and Home-Flex underground PE pipe (https://homeflex.com/underground/#system) is already layed out as you can see in the left corner. I am trying to figure out the best way to get under the sidewalk and which way to connect it to the meter. There is a second outlet after the meter that is currently capped and my plan it to connect into it.
- Should I connect as shown by the green or purple route? Green will "cross" the gas supply that is shown in yellow (but will be above is as far as depth) and may also extend past the window. Esthetically, this does not feel right. However, it give me more space to maneuver to the left of the sidewalk.
- Purple has the benefit of not crossing the supply in the ground, but is a bit close to the sidewalk. The meter risers are pretty large (30x30 inch L) and connection point of PE coupling and gas riser will eventually have to be shifted under the sidewalk.
- Is meter riser even needed or can just go down with black iron pipe and 90degree horizontal, go under sidewalk with black pipe and connect to Yellow pipe on the other side of the sidewalk for a long 80 foot run. If I were to do this in black pipe, I would use the purple option. 3a) I see that all gas pipes that come from underground are painted gray and not black, what type of pipe is it and is my idea of using black gas pipe even valid.
