Just wondering does anyone know where to get propane tanks re certified (not cylinders) i.e 500 and 1000 gallon tanks. I talked with coop but they are only doing the ones that they rent out for the foreseeable future. From what I understand the new regs grant a grace period until 2024. So old tanks as long as they are sound and are 250psi rated can be filled until 2024. However after that they need to be re certified. It doesnt sound like a real big deal to do, but have not been able to find out who does it yet, does anyone know?
