Propane line in conduit?
My contractor buried a schedule 40 conduit 18" deep under the gravel bed underlying what will be a flagstone patio. His idea is that the propane company will fish the propane line through the conduit. The propane line is for a fire pit. I'm traveling, but presume he thinks the required tracer tape will be fished along with the propane line.
Is this in any way legal? If so, how would one make the conduit ends weather-tight?
I'm inclined to make him dig it up and put a gas line in and leave the conduit for what it was designed, power. No, I'm not planning to pull both gas and power in the same conduit.
