Don't know and honestly don't care as long as the liquid is recirculating somehow and there are no flow restrictions. I don't need it to go through the grain bed because BIAB does not rely on the grain bed for filtering. (That's what the bag is for.) I am recirculating simply for the purpose of maintaining an even temperature and avoiding heat stratification during the mash.
