We have a well and in winter the tap water get near freezing. It actually does freeze sometimes. We will get a copper test kit and just out of curiosity test our hot water, but for now we fill a large bath tub with cold tap water the day before and add pots of boiled water to get it to temp and got a submersible pump to pump the water out and into the tanks. Works almost as well as going straight from the faucet with a hose, but its still a bit of a hassle. How does everyone else deal with water changes in winter?
