I brewed my first batch today using my new single tier HERMS. It is also my first time using a pump. I had so many issues with it, that I almost want to tear it apart and go back to gravity.
I couldn't get the pump to push through my coil. At first, I had a 50 ft coil comprised of 2 25' 3/8 coils. That wouldn't work. So then I took one of the coils out. It still wouldn't push through it consistently. I abandoned the HERMS completely and ended up with a mash way on the low side. Oh well, it will be a dry Belgian Wit.
I also couldn't get the pump to pull through the mash. When I had the outflow dialed down to the point where it wouldn't get stuck, the pump would lose siphon and pump air.
I use soft silicone hoses. You can see the setup here
Anyone have any ideas? Anyone else have these kinds of issues when they first went March?
