Propane Gas Line Under Concrete Slab

Lead 90 flush with concrete slab.

Propane gas line under concrete slab.

I m traveling but presume he thinks the required tracer tape will be fished along with the propane line. 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. A truck delivering your propane could crack the concrete covers and lids that protect your septic tank. Propane is heavier than air which is why you can never install a propane line under any slab under any conditions.

Drain and sewer cleaning. Under slab gas line. Because gas is heavier than air it wont escape natural gas is lighter than air so it will escape through the vent. Gas line in sewer.

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. The propane line is for a fire pit. 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. 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.

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. His idea is that the propane company will fish the propane line through the conduit. Look for overhead power lines upon installation.
