is it possible to use the float switch with a asco type valve to control wort flow? I would like to use it with my hop back, the level of my hop back is below my boil pot so the wort bleeds back from the pump and turning off the pump will not work.
It is perfectly possible to do it this way. There is little difference between switching a pump or switching an ASCO valve. It only assumes that you have a gravity flow setup. In fact, I have the parts to do exactly this, but just have not yet put it together.
