How do I winterize my home’s water supply?

Turn off the water at the exterior. Make sure that the water supply is turned off completely at the main supply point. If the furnace should fail on a very cold day, water in a pipe could freeze and burst the pipe. To turn water off to the exterior please call the Dover Township Water Dept @ 717-292-3634Note: The water meter should be disconnected and Drained to prevent meter from damage.

  1. Open all faucets and drain all waterlines. If you live in an area where freezing pipes can be a problem, drain the toilets, the water heater (turn off the gas or electric supply first) and the expansion tank.
    • get a air compressor to blow the lines of excess water. Eliminate or dilute the water in drain traps by pouring an “RV” type antifreeze solution into them, as directed by the instructions.
    • Close the sink and tub drains.
    • If a house is to be vacant for a long time, you may prevent water in a toilet’s trap from evaporating (and thereby permitting sewer gases to enter the home) by raising the toilet’s lid and seat and covering the bowl with saran wrap.
    • Turn off and drain fountains and other sources of standing water.
    • Drain water from dishwashers and pour RV antifreeze. with refrigerators (with a water dispenser or an ice maker) and washing machines, following the manufacturer’s directions. Remove the water filter from inside the refrigerator.
