From the Dublin San Ramon Services District:
If you have no water in your home after a very cold night, chances are good that water is frozen in the pipes. Taking a few simple precautions before temperatures drop can help prevent the mess, money, and aggravation of frozen pipes.
- Hose bibs and exposed pipes on exterior walls are at most risk of freezing. Insulate them with pipe insulation sleeves, UL-listed “heat tape” or “heat cable,” and similar products sold at hardware stores.
- Winterize hose bibs, pools, and sprinkler systems by shutting valves that supply water to them and draining remaining water from the supply lines.
- If you will be away during cold weather, leave the heat on in your home set to 55ºF.
