Hi, everyone. I do small batches (1 gallon final volume in the fermentor) and I would like to add a pump to my system. I currently recirculate by hand...an hour for the mash, then do a first runnings, then recirculate my sparge for 15 minutes. Works well. But, I would like to use a pump. Stick with me on this... I have bought a little 12V DC pump, rated at 9 litres per minute, and I connected it to my mash tun ball valve with a silicon hose. It did not like it at all. Firstly, that hose deformed with the heat of the mash (reinforced silicon required) and I couldn't get the wort to the pump no matter how I tried. I had it with the ball valve fully open, and open at other amounts from near full to almost fully closed. Nothing worked. As a result no liquid was getting through the pump and back into the mash tun. I did try a water only run the day before and it worked perfectly, so I'm hoping some of you have experience of such a problem and can give me some advice. I have a few ideas. 1: Do I need to regulate the flow from the outlet of the pump as well as from the outlet of the mash tun, sort of balance the resistance with a second valve, if you get my meaning? 2: Do pumps generally not perform well with such small water volumes? 3: Should I not even bother, put on some big boys pants, and get a bigger system? (Really don't want to do that). I thank you in advance for your time and patience with this newb's gripes.
