Thanks for the information on the water heater. I never shut my water off I have city water but maybe I should in the basement.
As for the water heater I have been shutting the gas one off for 2 years now especially in the winter and the electric one before that. I have never heard of legionnaires (serious disease) festering in the heaters. As for cost my previous electric water heater would run all the time in the winter months.
