Your sump pump needs attention prior to winter. Otherwise, a lack of maintenance can mean a flooded basement when the spring rains arrive. Melted snow can also overwhelm the system, leaving behind a pool of water, damaged furnishings, and mold. But here’s how to winterize your outdoor sump pump and avoid trouble:

How to Winterize Your Outdoor Sump Pump

 

1. Never Let Water Stagnate

Moving water is unlikely to freeze. But if water pools below your sump pump and freezes, it can cause irreparable damage. To prevent this, allow water to flow through the sump pump. And if you can, leave a cold water tap open slightly during the winter to prevent your pipes from freezing.

2. Remove the Discharge Hose

When cold weather is coming, remove the hose that connects the pump to the discharge pipe. If the water freezes, the hose will become unusable and may be damaged. But remember to reattach it in spring or during a winter thaw; you’ll need it to get the water out. *It’s also a good idea to keep an extra discharge hose around. If the first one freezes or breaks, you can then attach the spare (and keep the first hose attached while thawing it).

3. Keep the Sump Pump Plugged In

In many locations, temperatures fluctuate throughout the winter, allowing snow to melt or rainstorms to occur. All this extra water will flood your basement if the sump pump isn’t plugged in. To play it safe, don’t unplug the pump.

4. Clean the Sump Pump Pit

Dirt, debris, and ice can clog the intake and discharge pipes. Check the sump pump pit before winter starts and throughout the season. If it’s completely filled with debris, hiring a professional to clean it out may pay off in the long run.

5. Bury the Discharge Pipe Below the Frost Line

Cold air can cause an exposed discharge pipe to freeze. The resulting blockage can cause the sump pump to burn out as it tries to push water through. You can insulate the pipe to prevent this; we also recommend, if possible, burying the discharge pump at least 12 centimeters below the frost line.

6. Protect and Insulate Your Pipes

To prevent freezing, bury pipe deeper in the ground, cover it with hay or tarp, or wrap it with insulation. You can also prevent leaks and freezing by insulating the intake and discharge line. These methods will keep water warm enough, so it doesn’t freeze in your pipes or sump pump.

7. Move the Discharge Pipe Further Away

The discharge pipe should release water at least 10 feet from the foundation of your home. Also make sure the pipe is sloped away, so water does not back up. But if the discharge pipe is too close, water can easily seep back in, causing your outdoor sump pump to run continuously.

8. Move the Discharge Pipe Farther from the Pump

There should be at least 20 feet between the pump and discharge hose (which should be freeze-resistant). This expands the distance between the sump pump and wastewater area. It also gives water more room to flow.

9. Install a Diverter Valve

A common feature in newer homes, a diverter valve allows water to flow away through an exterior wall or directly into the sewer system. It is effective for preventing exterior pipe freezing in colder climates.

10. Install a Drain Tile Around the Foundation

It’s often unavoidable to have water accumulate around the foundation. A drain tile, often a perforated pipe, runs along the foundation and moves water to the sump pump pit. The pump then directs the water out of the basement.

 

Additional Tips to Maintain Your Outdoor Sump Pump in Winter

After ensuring your outdoor sump pump is winterized, it’s essential to follow a few extra steps to keep your system running smoothly. Proper sump pump maintenance not only prevents flooding and water damage but also ensures the longevity of your plumbing system. Here are a few more tips to help maintain the efficiency of your sump pump throughout the winter months.

 

Inspect and Replace the Check Valve

A check valve is a crucial component of any sump pump system, as it prevents backflow into the sump pit. Over time, wear and tear can cause the check valve to malfunction, which can lead to water re-entering your basement or yard drainage system. Inspect the valve regularly to ensure it’s functioning correctly. If the valve shows signs of corrosion or debris buildup, consider replacing it. A properly working check valve ensures that groundwater, rain, and sewage are directed away from your home, reducing the risk of flooding.

 

Keep Your Plumbing and Electrical System in Check

Your sump pump depends heavily on electricity to function. Therefore, it’s essential to ensure the wiring is in good condition. Work with a licensed electrician to inspect the electrical conduit and wiring to avoid issues that can lead to sump pump failure. Furthermore, install a backup system such as a battery backup to ensure your pump keeps working during power outages.

Regular checks of the circuit breaker and sump pump switch will help prevent issues that could arise from electrical faults.

For extra protection, make sure your home’s plumbing, including pipes and valves, is properly insulated. This will prevent water from freezing in the pipes, especially around the exterior sump pump. Remember to install a ball valve on any plumbing running to the sump pump for easy maintenance and to isolate water flow during repairs.

 

Prevent Water Damage with Exterior Measures

Winter can be tough on your home’s exterior, so take measures to protect the foundation and roof from excess moisture. Yard drainage systems, including French drains or trench drains, are highly effective in directing water away from your home and preventing it from seeping into your basement. If possible, extend your discharge pipe to a dry well or a storm drain. This helps keep water away from your sump pit, especially during heavy rain and snowmelt.

Also, inspect the area around your home’s foundation, such as patios and yards, for any low spots that may allow water to pool. If needed, use gravel or polyethylene plastic to cover these areas and prevent water from entering your home.
