I backflush my shirron using my sink. It's got the adaptor that will allow you to hook up a hose to it. I use a female hose fitting with 1/2 barb setup and 1/2 inch tubing attached via hose clamp. The hose is just long enough to comfortably go over the 1/2 inch barbed fittings on the chiller. Attach the hose to the chiller, turn on your water (preferably hot) full blast and flus the chiller. I usually go back and forth between the wort out and wort in at least 6 times, 1 minute (sometimes more) each time, with the water on full blast until I have seen nothing come out in a cycle. The hose fittings with 1/2 inch barbs are available at home depot or your LHBS and will attach to any laundry sink, or to your kitchen sink if you replace the standard kitchen sink fitting with an adaptor.
