Just got a new LP5 recovery tank, evacuated the nitrogen and vacuumed it down. I purchased a Robinair Can Tapper. I made an 8" hose with 1/4" jic female ends. The Can Tap has a valve in it that I assume needs to be removed to let butane flow out but when I remove it, it is now an open valve that allows flow both ways. what is the proper procedure and equipment to load the cans into the recovery tank? I guess I need to add a ball valve to the hose where it joins the tapper and will need to bleed a little butane off every time I add another can.
Thanks for your time and consideration everyone!
Yup, add a ball valve as close to the can tapper as possible. RSD refrigeration supply has 8" hoses with a ball valve attached.
Just close it when you switch cans.
