Correct adjustment of water flow to condenser.

[Vickypoint]

Can you please advise of the correct procedure of adjusting the water flow to the condenser during the operation of a Bokakob style 2 inch 1.3 mt high still. I have made a double helix coil 1/4 inch copper for that unit. The column is packed with copper scrubbers.

I run a pond pump in a 200 litre water container which is recycled into that container. The pump will do 500 litres per hour. I have a tap between the pump and the condenser for flow adjustment.

Thanks
