Thanks for the info Eric and Lerpy. according to the owner. i just need company training on filling. Apparently the course for VIP is a money grab he says. the tanks are filled off banks; high and low pressure. i’m not comfortable doing VIP but ill fill tanks with the training ive had. The company is in southern Ontario but thats all the info ill give. not near you Lerpy. i’m only here four four months so i dont think the owner wants to pay for the course. Just to confirm this Lerpy, I DO need a license to fill from banks with normal air?
