How to Winterize Water Softeners

Water softeners need to be winterized for the cold as part of an overall preparation for the change in seasons. Homes are winterized when the residents will be away for an extended period while leaving the heat off. Pipes can be damaged or burst if a home is not prepared.

  2. Unplug the water softener.

  3. Turn the softener's manual bypass valve, if applicable, to the bypass position. This removes the softener from the water-flow loop.
