i know that here in the usa you are supposed to have the tank inspected 5 years after manufacture date.

but i was wondering if the tank is never taken off the property and is just used as a storage tank do you still have to have it inspected?

i recycle metals and i get old window air conditioners that people throw out and up until recently i had no way to recover the charge and would have to rely on someone to remove the charge.

i have a friend that works on refrigeration and can take the charge and he has a recovery pump.

i was wondering if i get a used or sometimes new tank on ebay that has been in storage and is nearing the 5 year mark if i can use that to store the charge.

my intent would be to collect the charge in the tank and have my friend come down to transfer the charge from my tank to his tank on site if i can get away with not having it inspected so long as my tank is not taken off the property?
