One piece of malt completely stops the pumps impeller. Can't figure how the grain is getting out of the malt pipe. The mesh was tight to the sieve, and the sieve sit tight in the malt tube. I'm also careful when adding the malt to the pipe. It seems to get past the top sieve when it starts to rise. Yambor44 did you use your stitched cloth covers and if so how did they work. I'm thinking of making a pair. I wonder if the cloth when wrapped around the edge of the sieve creates a better seal. Was able to salvage the batch using the March pump. O.G. came in as expected but needed to mash longer to get complete conversion. Also, even though I vorlaufed the wort wasn't as clear as when circulating up as the BM does.
Yes I did and yes they did. Even cleaned well! So far so good but I reserve the right to change my opinion if they don't hold up!!
