Steve, You are right. I remember in the summer that the water coming out of the hose was so cold that we would fill the great big galvanized tub and let it sit in the backyard so that the sun would warm it before we bathed our big collie. Looking back, we could have easily brought some hot water from inside, but I guess we were doing it the way my father did as he grew up in a time of limited hot water. The rinse was like the Resource Saver, a cold spray rinse from the hose. It would be interesting to see if the tap water at our old house was still cold or if it was much warmer now, but I would not get out of my car back there anymore.
