How to Winterize a Sump Drain

Sump drains prevent flooding in the basement.

If you leave your home for an extended period in the winter, you may be surprised when you get home to find sewer water in the home or burst pipes. Winterization of the sump pump and drains in your home is an essential step to closing down the home in the winter. The sump pump, if working properly throughout the winter, will prevent flooding of the basement and sewer water from flowing up into the home.

Things You'll Need

• Screwdriver
• Diffuser cap
• Wrench

Instructions

1. Locate the sump pump in the basement of the home.

2. Loosen the screw that holds the sump pump discharge drain line onto the pump. Pull the discharge drain line off the pump. Place a diffuser cap on the end of the sump pump pipe to prevent water from entering and freezing in the pump.

3. Tighten all the connections on the sump pump.

4. Change the batteries in the high water alarm on the pump.

5. Angle the drainage pipes coming from the sump pump downward to prevent water from remaining in the pump during the winter.
