About This Service
Propane Cylinders Must Be Re-Certified Every 10 Years
Re-certification, sometimes referred to as re-qualification, includes a visual inspection followed by the replacement of the relief valve and the embedding of a new stamp into the steel collar, which shows the latest inspection date. The cylinder must be empty of propane.
Cylinders cannot be re-certified if they have:
-
excessive rust
-
gouging
-
denting
-
bulging
-
dented welds
-
broken or damaged collars or foot rings
-
been involved in a fire
Most propane cylinders can be re-certified while you wait as it usually only takes about 15 – 20 minutes. If your cylinder has propane in it, we will have to burn it off before we can re-certify it, and this will take a little longer or if you wish you can pick up your cylinder another day.
