Pilot Outage

If the pilot is out:

  • Do not attempt to relight the pilot
  • Immediately turn off the gas supply at the tank
  • Contact McMahan's Bottle Gas

When you call McMahan's Bottle Gas, we will check our office records for the date of your last delivery. If it is possible you could be out of gas, we will dispatch a delivery truck to refill your tank. We will bubble test all fittings and appliance connections, pressure test the system and relight all pilots.

It is our policy to inform you at the time of your call as to any possible charges related to out-of-gas situations, special trip charges or service charges.
