I have discovered that the water pump on the Jobo CPA-2 that I purchased does not work. I have also figured out that it is definitely the pump and not a problem with the circuit board. People have talked about using a garden pump as a quick replacement and I was wondering if anyone had any instructions on using an alternative pump. Exactly what type of pump should I be looking at and how do I install it? I have made contacts that have offered to sell me the actual Jobo part but money is tight right now and I am becoming increasingly impatient with this processor. Any help you could offer would be greatly appreciated. Thanks!
