Winterize Your Water Service

Public Works receives numerous inquiries on how to “winterize” a water service. You may need to winterize your home’s water service if your home will be vacant due to move/sale of your home, an extended vacation, or home renovations that require having the water shut off, etc.  
Here are a few suggestions to avoid frozen pipes: 
    •  Pipes MUST BE DRAINED when water is turned off for an extended period of time. 
    •  Always allow heated air to circulate around pipes and water meters. Insulate problem areas and leave cabinet doors open. 
    •  In empty/vacant homes, don’t turn off the heat—instead turn down thermostats to maintain a minimum temperature to keep pipes from freezing. Installing a programmable thermostat is recommended to regulate the temperature when needed. 
    •  Allow water to slowly drip from faucets with water pipes adjacent to an outside wall.  
    •  Do not use an air compressor to “blow out” a private water service. This can allow dirt and other contaminants to enter the private and public water supply causing a potential health risk to residents and others drinking City water. 
If you have any questions, please contact Public Works Department at 630.377.4405.
