If you are going to be gone for an extended period of time (more than a couple of days), shut off the water in your house for precautionary sake. In case the house would freeze up, with the water shut off, NO damage from a broken pipe. In our homes, we make it easy to shut off the water.
Pictured beneath is the water meter; there is a valve on either side of the meter that will shut off the water. Just a few seconds and you don’t have to worry about a sudden cold snap, which can happen in January in Ohio or other parts of the country. This can be an important practice even if you are renting. One of our renters called me before they left for the Christmas holidays and we shut off their water while they were gone.
The reason for this picture? When they got home they didn’t know how to turn the water back on!

Shutting off water when not in use can help prevent frozen and broken pipes.
