thermometer that will measure down to zero degrees Fahrenheit.
-
Make sure you are not running any appliances such as dishwasher or
clothes washer.
-
Go to your kitchen sink and turn on the the cold water and let it
run about a minute. Hold the end of the thermometer into the cold
water for another minute. This will tell you what the ambient
temperature of the water coming into your house is.

temperature of the water to be between 42 and 54 degrees all year
