Hi, I am going to be building a RIMS setup soon, and I had a few preliminary questions that I didn't find answered elsewhere, so I thought I'd post.
I've attached a drawing of my basic setup.
I've never used a pump or RIMS tube before, so I wanted to check on a few things.
1) To "prime" the pump, do I simply open the valve on the MLT to let the wort flow into the pump, and leave the valve on the pump outlet closed? Or should the outlet valve be open for this?
2) I've seen RIMS tubes placed both horizontally and vertically in various setups. Are there advantages to either way, or is it mostly due to how it fits your particular setup?
3) I'll be using a Chugger pump. The FAQ for the pump says to not run it dry. Does this mean I have to leave some wort in the hoses when I turn off the pump? Or does that mean the pump has to have some liquid in the head before turning it on?
