How to Avoid Frozen Sump Pump Discharge Lines

Sump pumps are some of the most underrated devices in the home. Typically, they stay in below-grade areas, ensuring floods from incoming water don’t wreak havoc on the basement.

Many areas experience a cycle of freeze, thaw, and refreezing in winter. Wild temperature fluctuations can cause water to freeze or back up in the drains or exterior discharge lines. This can lead to serious problems inside the home, like water seepage and flooding.

This article explains the cause of frozen discharge lines, how they impact your home, and how JES Foundation Repair can help you protect your home with innovative and reliable basement waterproofing solutions.

Why Do Drainage Lines Freeze? 

When outside temperatures dip below 32°F, water will freeze. You’re likely to find puddles frozen and ice in your yard. Whenever the sump pump ejects water from the basement, it can freeze on the discharge line due to the freezing conditions. Some homeowners don’t realize the freezing can happen on the pipes as well. Layers of ice will build up and eventually block water from exiting the line. Water from your basement will back up, as it has nowhere to go. 

What Can Happen When Discharge Lines Freeze? 

Your basement will start flooding, and this can lead to severe foundation damage. In addition, your sump pump will run continually, and then fail eventually because it’s overheating while trying to empty the basement. How long this takes isn’t clear. But commercial-grade pumps can manage to function for some time before they burn out. Either way, sump pump failure is bad news for your basement. 

Protecting Your Discharge Line 

While you can’t control the temperatures outside your home, you can take active measures to protect your sump pump and its discharge line. One way to do this is to construct the discharge line in a way that doesn’t freeze over. The discharge line for the sump pump should extend a minimum of 10 feet on the outside. If it ends right on the foundation wall, water will likely seep back into your basement.

Typically, these lines are buried or extended out and above the grade. If you choose to bury yours, make sure they stay below the frost line. Pipes that run above the ground present a different challenge, but it’s one that can be remedied. When laying down these pipes, make sure they follow a downward slope so water keeps flowing. Water in the pipe is likely to freeze if the line runs straight horizontally. Changing the line’s gradient can mean the difference between keeping the basement or crawl space interior dry and allowing it to flood. 

Invest in Exterior Protection

If you live in an area where the sump pump’s discharge line is prone to freezing in winter, consider installing a FreezeGuard™. It’s the cure for frozen and blocked lines due to plummeting temperatures and ice. This anti-freeze device works like an overflow valve. Placed vertically, it allows water to escape through open slots without spilling during repeated pump cycles, forestalling basement flooding. 

Even if your drains or discharge lines freeze, the FreezeGuard™ will still be able to keep water out of your basement. There’s less fuss, as it has no valves to turn and doesn’t require a hose to be attached. 

Additional Tips

Here are a few other tips to follow regarding your discharge lines. 

  • Insulate the intake section, as it’s vulnerable to freezing. A large diameter does the trick. 
  • If the discharge line freezes, thaw it with a portable heater, as it is non-intrusive. 
  • Inspect the sump basin regularly and test your sump pump to ensure it’s functioning properly. 

JES Can Help You Protect Your Sump Pump 

Your sump pump has one purpose, and that’s to expel water that seeps into your home. While this device sees little action in the dry summer, winter months can be particularly hard on it. You want to make sure it stays protected, and the best way to do that is to add a FreezeGuard™ to its discharge line.
