How Do You Keep a Sump Pump Discharge from Freezing?

During the cold months, sump pump discharge lines can freeze because of the low temperatures. Once frozen, the discharge line cannot properly carry water from your home. This problem may cause your sump pump to fail and lead to your home flooding.

However, with the Freeze Relief, you can rest easy. Our impressive device helps prevent flooding and divert water in frozen discharge lines so that you can escape the cold in the comfort of a dry home.

What is the Freeze Relief?

The Freeze Relief Discharge Line Protector is an essential tool for protecting your sump pump’s discharge line. When a discharge line becomes clogged with dirt, ice, or debris, the pressure will build. When your sump pump is turned on, water is dumped into the clogged pipe. Massive water pressure and clogged discharge lines will lead to a broken sump pump and a wet basement.

Luckily, the Freeze Relief allows excess water to spill out of the pipe instead of building over time. The Freeze Relief excels at relieving pressure. This relief will give you more time to fix the issue and clear any remaining debris in your discharge line.

How Does Our Discharge Line Protector Work?

Our product replaces the vertical portion of your existing discharge line. Our discharge line protector acts as a transition piece between the two pipes. Additionally, the Freeze Relief is compatible with any sump pump with an above-ground 1-½” PVC pipe. Furthermore, this pipe must connect to a more extensive underground discharge line. Lastly, our product comes in two sizes: 3” and 4”.

Freeze Relief Features:

  • Easy Installation
  • Two different sizes
  • Maintenance-free PVC (No plugs, valves, or hoses)
  • Prevents pressure buildup, sump pump burnout, and basement flooding
