Only problem with testing tanks is they fill them with water during the hydrotest process. If you ever intend to use them as reclaim tanks to hold refrigerant while servicing a system the tanks will need special processing that most welding supplys do not do.
You do not want wet tanks while doing service work
For every 30lbs of r22 we exchange they sell us a virgin drum for $200 vs the $485 to buy a single drum. They don't care if the tank is out of date or not.
jtrammel do you mind saying what supply house does that. Seems like a pretty decent deal.
Even though we got 40 tanks that we split up in 4 different locations that we paid $425 after tax Hell only paying $200 for a new tank of r22 is a pretty good deal
