New Propane tank purging is important.

7th Jun 2019

Why does my new propane tank not fill properly?

  • All new propane tanks must be purged of air and moisture before being filled for the first time with propane. 
  • The purging process, which must be done by a trained propane service professional, requires that a small amount of propane vapor gas be injected into the tank and then evacuated. This process is performed 3-4 times. Do not attempt this purging on your own.  Always have a qualified professional purge your tank.
  • Propane is heavier than air and will force the air out of the propane tank during the evacuation of the vapor. 
  • Filling with propane can then proceed. 
  • If the tank is not purged, then air is the first gas to exit the propane cylinder and your appliance will not function properly.
