The still is hard to run at best. But you can pull 95 in one go, but you have to be careful and patient. There is no seperate water in and out for the coil and the jacketed body. You need water in at the coil and water out near the base. You need some back pressure or the jacketed body will drain. Or you will run it too cold and choke/spew.
I ran the water out over the top o the head and then down into the sink. Adjusting at the tap and valve for change in flow. Couldn't get it to work with a restricting valve on the water out.
Sorry for the ramble hope it helps.
