Prevent Sump Pump Discharge Line from Freezing

A suspended sump pump discharge hose indicates bad news for homeowners that have sump pumps installed in their cellar. If a sump pump hose stinks, the pump will work harder and will eventually fail because of overheating.

Meaning that it will not do its job of discharging water that accumulates around the base. Therefore, it’s vital that you help prevent sump pump lines from freezing to keep the cellar protected from the flood. 

The objective of a sump pump, of course, is to expel any rainwater that seeps into your home. You may expect that water intrusion is not a problem in winter, but that’s rarely true. Rather than rain, you are coping with melted snow (even though we receive our share of chilly rains, too).

Tips to Prevent a Sump Pump Discharge Line from Freezing

  • The sump pump discharge line must be either buried from the yard or extended out above-grade in a downward slope.
    1. When the pipe is buried, it needs to be buried at least 12 centimeters below the frost line (the maximum thickness of earth below that the soil does not freeze). The section of pipe where the pipe meets the earth in the frost line and at the end of the line where the water disperses is where the pipe usually freezes.
    2. Property owners who select an above-grade solution must extend the release line from the house at a downward slope. The pitch does not have to be intense, but continuous so that the water can flow. A hose that’s smooth, rigid, and freeze-resistant should be joined to the end of the discharge hose, and ought to release water at least 6 meters away from the base. If the pipe is properly sloped, gravity can help keep the water flowing (standing water from the pipe is more likely to freeze).
  • The sump pump discharge line and the ingestion section ought to be insulated to guard against freezing. A larger diameter pipe may be connected to the end of the sump pump hose with wires and clamps, leaving an air gap between the hose and the larger pipe. As a more straightforward insulation alternative, the exterior pipe can be covered with hay (a natural insulator) along with a tarp. Automotive anti-freeze shouldn’t be poured into the toaster.
  • The sump basin ought to be checked regularly, along the sump pump also needs to be tested from time to time to make sure it’s working properly. Also, the sump pump must not discharge water onto the sidewalk and drive to prevent dangerous ice.
  • If the sump pump tube is rooted, portable heaters may be used to thaw it. Using a blow torch to thaw the line is a bad idea as that can cause injury or damage to the property. If DIY thawing isn’t possible, it is ideal to call a professional builder to thaw the line out. Learn more about water remediation here.
