Hi BeerCat,
Have you worked out why your pump is getting clogged?
I conditioned the grain for the first run of the "system" and had absolutely no problems with the pump. Conditioning is supposed prevent the grain hulls from getting torn up in the mill (or at least reduce the tearing), thereby making a better filter bed.
I also underlet the grain, which meant I could put the unmilled flaked barley in first to build a filter bed (I was brewing a milk stout).
I followed your advice and didn't install the Y-filter. Why do you think it works fine now that it's been repositioned?
I was expecting lots of pump problems, but everything went smoothly.
I've modded the ACE to connect up the 900W element. I'm going to put a voltage regulator into the circuit to make the 900W element adjustable - once the full boil is achieved I'll dial down the 900W element to get a decent rolling boil.
