Propane Piping 101

 height=

Only approved materials and fittings are to be used for any part of a propane gas service line. Materials such as PVC, rubber hose and flex lines are illegal and are not to be used in any part of the gas service line.

Important Note About Underground Piping Materials– Allowable materials used for underground piping/tubing vary from state to state. Copper tubing is not an approved underground piping material in some states. Consult a licensed propane company in your state for more information about approved underground gas piping and yard line requirements.

Propane Line Depth Requirements

The yard line is subject to depth requirements for the protection of the line and connections on either end. Depths range from 12 to 18 inches underground, depending on vehicular traffic. The reason for this depth requirement is simple – the earth, dirt, sand or whatever is covering the line needs to adequately protect the underground gas line from damage

The inadvertent movement of the gas service line can cause leaks to form at the connections on either end of the line. For these simple reasons, the gas line needs to be buried at a safe and required depth.
