porschedude996TT obviously has plumbing background.
For clarification:
The original meter installation consists of the grey riser that comes up on the left (service side), the meter, and a whoop-de-do turn to get back to the hole in the house where the gas line enters. The grey riser with regulator is the "service" side of the meter, and the top right is the "house" side.
What the plumber just added is the elbow at top right, ball-valve shutoff, the 180 degree turn to connect to the yellow MDPE gas line, which goes out across the back yard to my shop.
What I see wrong are two things, both mentioned by porschedude996TT above:
1. There is no tracer wire on the new MDPE line, making it impossible to find with a detector.
2. To the best of my knowledge, MDPE yellow pipe is not supposed to be installed above ground, or left in direct sunlight. They make a black version that is UV stabilized for exposed locations. Even the storage in sunlight is listed as three years maximum in the specifications I can find.
Anyone that can confirm this about the MDPE, please chime in here.
Thanks.
