How to Prevent Your Sump Pump Line from Freezing

When freezing temperatures hit New Jersey, one of the most common winter plumbing issues homeowners face is a frozen sump pump discharge hose. When this happens, water can no longer flow out of the sump system, forcing the pump to work overtime. As it struggles to push water through the frozen line, the motor can overheat and fail completely. The next time water collects in your sump basin, you could face serious flooding and water damage in your basement.

To help you avoid that headache, here are some professional tips from PuroClean of Middlesex for keeping your sump pump line clear and functional all winter long.

Sump Pump Maintenance Tips

Outside your home, make sure the sump pump discharge line is properly positioned. It should either be buried in the ground or raised above grade at a downward angle to allow water to flow freely away from the foundation.

To protect the pipe from freezing, bury it at least five inches below the frost line (the maximum depth of ground below which the soil doesn’t freeze). The pipe’s most vulnerable area is where it joins the earth at the frost line and where the water disperses.

For above-ground discharge setups, the pipe should extend away from the house at a steady, downward slope. The angle doesn’t need to be steep, but it must be continuous so that water flows naturally out of the pipe instead of pooling.

To further reduce the risk of freezing, connect a freeze-resistant hose to the end of the discharge line and ensure the outlet releases water at least 20 feet away from your foundation. This prevents water from seeping back toward your home and reduces the chance of basement flooding.

When possible, use a smooth, rigid hose instead of a flexible corrugated one. Rigid hoses are less likely to trap small amounts of water that can freeze inside the pipe.

To keep the discharge and intake sections of the sump pump frozen, insulate them and the pipe connecting the two. Cover the outside pipe with hay (a natural insulator) and a tarp for a more basic repair. Don’t put any anti-freeze in the sump pump.

Check your sump basin and test the sump pump from time to time to ensure that it is in good working order. Make sure nothing is blocking your flex discharge line, including snow, ice. Also, make sure your pump doesn’t shoot water onto your sidewalk or driveway, as this can create hazardous ice.

If you discover that your sump pump discharge line has frozen, never use a blow torch or open flame to thaw it. Doing so can damage the pipe or even start a fire. Instead, use portable space heaters, heat tape, or a hair dryer to gently warm the frozen section.

If you’re unable to thaw the pipe safely or the pump has already stopped working, turn off the sump pump immediately to prevent motor burnout and call a professional plumber for assistance.
