Well I'm in final stages of my 3 vessel keggle build. I will be running a blichmann tower of power module. So I wanna add a recirculation port using a cam lock. Can anyone post some pics of there port placements. I understand ya won't need a ball valve since the placement should be high. Was also thinking of adding a whirlpool port on my BK...This I assume ya need a ball valve for..any pics of these ports on your vessels would be appreciated...thanks, cheers!!
