So I have two questions regarding the pump:
First thing I did was faucet -> pump intake -> small temp coil in pot -> drain
Ended up overflowing my pot? Why?

Second thing I tried:
Pot on stove -> small temp coil in mash tun -> pump -> same pot on stove
I lost all my water? It just went poof? I thought I could get a nice circulation going, but I just lost all my hot water :-(
