I am making a HLT and MLT out of used commercia l sink I obtained from a restaurant that closed down. It has two sink compartments and a side board. The sinks hold about 14 gallons each so I should be good for 5 gallon batches. I am planning on making it an electric HERMS system. The sinks have 2 inch male threads on the drain. McMaster has a reducer to 1/2" but it cost close to $60/reducer. Anyone know if another fitting site that may have something cheaper or another idea for coming out of the bottom?
