Thanks for the advice Keith. I just filled the each slot of the Jobo 3005 to the top with water and laid it on it's side and rotated it until the excess water poured out. (to get as much water in the drum as possible while still laying on it's side) And as I was drying the tank off to put in a tray for next day inspection I noticed the bottom of the drum continued to drip water.


Looks like I will be returning this to the seller


Thank you again for the advice. It's much appreciated!
