If you have received a red tag it simply means that a TSSA certified gas technician has deemed your equipment to be unsafe to use in its current condition.  Depending on the severity, your gas supply may have been turned off completely.  In either case, the violation MUST be cleared by a TSSA certified technician.  At Bradshaw Gas Services, we understand the urgency in getting your appliances back up and running and always prioritize warning tags with same day/night repair available at no extra cost.
