Hi all, I am going to build an electric 3 kettle system with two pumps a chill plate and a herms tube. I have a guy that will build the kettles for cheap but want to make sure I get everything correct as far as the number of fittings on each kettle. Looking to do it all right the first time. Going to use 1.5 tri clamp fittings on everything. I will have drains right there and water right there too. Really looking for some help in placement and number of fitting I need for each kettle. Have been looking but can't find anything for a system like this. Any help is greatly appreciated!
