Well, I think tank certification is for your safety, too, and that of your crew, guests, and neighbors.Or just go to your local Ace and hope the 17 YO kid doesn't notice.
Seems that a visual test is worthless, other than allowing you to refill. Doesn’t really assure that the tank is safe to use without removing the valve and inspecting inside as well as pressure testing.There is a local propane and welding supply in my town that re-certs for about $15-20. It's not a pressure test, just a visual. Good for 5 more years.
CFR requires a visual inspection prior to any fill. A visual “test “ can be in place of a actual hydro test and that meets the hydro requirement for 5 years. This visual test involves removing the valve and inspecting the inside (and outside). Rust and failed OPDs are the main issue with lPG tanks. The actual hydro involves fill the tank to test pressure and is good for 10 years.both types of tests require visual inspection prior to fill regardless.Seems that a visual test is worthless, other than allowing you to refill.
