I have five tanks. They are older and have not been hydrotested in a long time. I had the tanks tested and filled, then got an artificial joint. I know when I had them tested, at least 4 were good. I had 7 and know one was bad. I pressure washed them and the test date labels came off. I traded two away, and told the guy one might be bad. I do not know which one of the seven was bad, so it could be one of the five. I tried to be honest. At this price, you get what you see.
