Propane Gas Line Under Concrete Slab

Gas pipe to kitchen island under concrete slab.

Propane gas line under concrete slab.

My contractor buried a schedule 40 conduit 18 deep under the gravel bed underlying what will be a flagstone patio. I know there could be a leak under the slab but there is only around two pounds of pressure in the gas line it seems unlikely gas would force it s way out if it was surrounded by compacted soil or in concrete. If you receive a delivery when it s dark outside or if the lines are hidden by trees your driver may not see the lines at all. How do i attach a new flange.

Lead 90 flush with concrete slab. Low hanging lines make it difficult for drivers to navigate. A truck delivering your propane could crack the concrete covers and lids that protect your septic tank. Under slab gas line.

Gas line in sewer. I call out gas lines being buried under an exterior slab without properly vented conduit but when people ask how serious a problem this is i have a hard time coming up with an answer. Drain and sewer cleaning. Look for overhead power lines upon installation.

Code seems to want the pipe to come up on the outside with a riser and seems opposed to entering the building in the wall or even thru a liner of some kind because of. I d really like to come up with the gas line inside the barn in the wall ideally so that the black steel pipe will be hidden thru a concrete slab that will soon be poured. Propane is heavier than air which is why you can never install a propane line under any slab under any conditions. The propane line is for a fire pit.
