what DJ_L3ThAL said..Benn said:Question for the electrically minded Brewers,
Could the flow be reversed by "reversing the polarity" to the motor or whatever it's called when you make an electric motor spin the opposite direction by switching the active/neutral?
Just thinking of the above for recirc/sparge application.
but whats the difference in your recirc to your sparge direction of flow.
Unless you are doing recirc up through the mash, liquid is still coming from 'somewhere' and going into the top of the grain bed. just use a valve to change where this liquid is coming from between mash and sparge
