    Locate your main shut-off valve

    Know where your main shut-off valve is located and how to turn it off.  It may be near the water heater, near an outside hose bib, inside the garage, in the basement or crawl space, or near the water meter.

    Who to call

    In the event of a severe winter storm, please reserve 911 for life threatening emergencies.
