What is an electrical bond on your gas line?

    An electrical bond is an electrically conductive and continuous path from the gas piping to the grounding electrode system.

    Why bond your gas line?

    Bonding is required to prevent a possible electric shock hazard for persons that may be in contact with gas piping and other grounded metallic building components. Gas piping can become energized by an electrical fault in the gas appliance that the gas line is attached to or from a nearby lightning strike. These things can cause an unbalanced voltage to build up and result in a high electrical potential difference. That potential difference can cause arcing on the gas line possibly resulting in damage to thin-walled CSST gas line piping which could result in fire or explosion.

    Dawson's Electric is your gas line bonding expert – we often do this service for homeowners at the selling of their house when a home inspector finds this problem. We also want to be proactive on this and check this on each service call along with the grounding system. If you have doubts if your gas line has ever been bonded call and schedule today for us to look at.


    CSST stands for corrugated stainless steel tubing. CSST bonding is the process by which the gas piping system is intentionally installed to the grounding electrode system. This creates a lower resistance way for electricity to connect with the earth, giving ground fault protection to a gas line and making it safer for a home’s residents.


    To ground a gas line will typically cost between $100 – $300, depending on the individual circumstances of how it was originally installed. For a more accurate price estimate, contact Dawson’s Electric today and we will be happy to assist you.


    Proper installation of a gas flex line, or CSST gas line, is crucial to the safety of a home. If not properly bonded, CSST lines are susceptible to damage from lightning strikes and could cause a house fire. During a lightning strike, energy can run through wiring into a house, then jump onto the gas flex line. The extra surge can cause damage to the line in the form of tiny holes, letting gas escape and potentially causing fires. Proper bonding of the gas flex line will prevent this from happening.
