I can't remember or find the thread this was supposed to go in, but here it is on its own. The new higher position for the 2nd tap/valve is better positioned for recirculating (cooling) big 1.5 batches. It helps to get cooling wort to the top for these big batches, I found. Otherwise a temperature gradient forms therefore extending cooling time, which defeats one of the key benefits behind the mod to recirculate. The lower one is better for half batches. If I'm making something simple, like half a batch of starter wort, I won't recirculate at all and plug both holes, as the lower one is in the pic, using the BM as it was designed and cooling with an immersion chiller rather than recirculating through and CFC.
