Hi all. Not sure if this is the correct place to post but here goes. I am (slowly) building my brew rig. All electric single tier and had been planning on using 3 pumps as I would like to do back to back batches and kind of like the idea of hard plumbing. When I first started designing it I had envisioned motorized valves as well. I have since ditched the idea if motorized valves. I really liked JonW's rig and based a lot of my 3 pump desires off of seeing it. now I'm having second thoughts as to whether or not to go with the 3rd pump. anyone have any good advice?
