Envirosafe argues that since hydrocarbons do not react to air, there's no need to pull a vacuum. It's a controversial claim for sure. I plan to pull a vacuum in round 2 anyway and maybe just find some r12.
Hopefully I've found the house that ruptured. The hoses actually look brand new. Not sure there was an unusual leak prior to this episode. |
Agree on the relative risk. Gallons of gasoline is potentially a LOT more dangerous that ounces of propane/butane.
20 years ago I tried the hydrocarbon mixtures (usually propane and butane) in an old van of mine. It worked, buy not as well as R12 or even 134. Forget about the risk, I changed to 134 because it wasn't worth the hassle to use non-standard refrigerants.
