As reported by Propane101 in their article “Underground Propane Piping – Yard Line,” the gas line connecting the propane tank to the structure housing the gas appliances, known as the service piping or yard line, is crucial for a safe and functional propane system. The yard line typically consists of copper tubing or plastic polyethylene piping and must be installed correctly and legally to ensure the entire outside portion of the installation is safe and serviceable.
Specializing in high-quality underground propane piping solutions that meet all legal and safety requirements, the company ensures the visible parts of the yard line emerge from the ground next to the tank and where it enters the building or connects to the point of use, such as a generator or pool heater. Only approved materials and fittings should be used for any part of a propane gas service line. Materials like PVC, rubber hoses, and flex lines are illegal and should not be used in any part of the gas service line.
Important Considerations for Underground Piping
State Regulations: Allowable materials for underground piping vary from state to state. While copper tubing is approved in some states, it is not permitted in others. It is essential to consult a licensed propane company in your state for information about approved underground gas piping and yard line requirements.
Depth Requirements: The yard line must be buried at a depth ranging from 12 to 18 inches, depending on vehicular traffic, to protect the line and connections. Proper burial prevents damage from vehicles and accidental tripping, which can lead to leaks at the connections.
Material Protection: Underground piping must be made of materials resistant to harsh underground conditions. Additional protective measures, such as placing the gas line in a PVC sleeve or wrapping it with protective tape, are necessary to prevent corrosion and propane leaks.
