Hi all : I am long time home brewer and a lot looooonger beer drinker, I am trying to get my Zimatic back up and running and am looking for advice ie you tube video on how to disassemble the case so I can install new pumps. Love the system but won't circulate properly anymore, Probably a lost cause but for now they are supporting their software and online recipes etc. Would much appreciate any insight, Thanks Gl7mm Minnesota
