Ah yes. Makes sense now that i see each vessel has its own pump so that it is always at the start of the loop it is using. Can also see that you are segmenting two different parts of the loop in order to be able to use two different pumps at the same time. Picture worth a thousand words Very clever. Is that a pro brewer standard or did you work that out on your lonesome?Here it is. No three way buy lots of 2 way valves. We can do two 25 gallon batches at the same time and even clean one Brew Kettle while the other is still in use.
Thx @staffordj I am going to leave my Proportional valve at the pump 2 outflow and then also have regular ones after that in serial for the two directions: mash tun re-circ and chiller. That will allow me to use the Proportional for both re-circ and chilling.You may get a stuck mash if the recirc flow is too high. My last batch I upped my flow from 1 gpm to 2gpm. The flow steadily reduced from 2 to 1.5 over 30mins as the bed compacted. This will depend on a lot of things like your grind, mash composition, vessel and screen, but not having control could lead to issues.
I have a manual 3 way that I can stick on the chiller out for now. one way to whirlpool, other way to fermenter. Will need to replace manual 3-way with a tee and two new motos at the chiller output so I can avoid the horror of touching a ball valve. I think that will officially max me out on uniflex v2 binary outputs (11)
Cheers for the help.
