[dropcap2]If[/dropcap2] your sewer is backed up or slow to drain, your first call should be to the natural gas utility serving the area. Why? There is a possibility that a natural gas pipe could have been inadvertently installed through your sewer pipe and the mechanical equipment used to unclog sewer pipes can penetrate the natural gas pipe and lead to the dangerous release of natural gas.
As long as a natural gas pipe is not penetrated, it poses no safety hazard. However, if you are having troubles with your sewer, or think you have a blockage, please call the natural gas utility serving the area first before anyone attempts to clear the sewer pipe.
