Frozen Discharge Lines

Fact: Frozen Discharge Lines can block pumping action and force water back into your basement. It is wise as a homeowner to get a cover for your discharge line to keep debris, and small animals out of it.

Sump pumps are known to generally discharge outside. As the temperature get relatively colder outside it’s no secret that freezing occurs. One of the worse things is when this “freezing” affects your discharge line. Whenever there is a sump discharge water is supposed to be released. However, this can’t take place if the pipes are frozen…in fact there’s a buildup. Whenever the sump pump attempts to release water that it can’t because of a back up, flooding occurs. It’s important that if you see signs of leaking or flooding, have your discharged line thoroughly checked. The longer you wait could make matters even worse.

Guard Against Frozen Discharge Lines




If you have a sump pump, it probably discharges outside. Snow and ice can block the opening and cause it to freeze. When this happens, your pump will be running and the water can’t get out, causing your basement to flood.

Preventing the discharge line from freezing will keep your basement from flooding, which saves you time and money.

Always be prepared

  • Discharge lines may freeze in the winter.
  • Street plows often cover outlets to the street causing water to back up and flood the basement.
  • If the line freezes, the basement may flood.
  • If you want the basement dry ALL the time, you need to protect against these problems.




BD Tip: Keep your discharge line to the street clear of debris and snow.
