Recommended Installation Setup
1-1/2" Sump Pump Line
Freeze Relief
4" Discharge Line
3" Buried Line
Important Note
Install Freeze Relief so the vents face away from the house. Maintain at least 12" clearance above ground level.
Installation Steps
Prepare Installation Area
Identify where your sump pump discharge line exits your home. Ensure you have clear access and enough space to work.
If installing a new elbow, put the 1-1/2" collar up to the band board with a little caulk for a finished look and better air seal.
Position Freeze Relief Unit
Install Freeze Relief in-line as the transition between the 1-1/2" sump pump line and the 3" or 4" buried discharge line.
- Ensure vents face away from the house
- Position top of Freeze Relief about 4" below elbow
- Maintain at least 12" clearance above ground
Connect to Discharge Line
Connect the Freeze Relief to your buried discharge line using the appropriate adapter:
- If your buried discharge line is 3", use the 4" to 3" reducer
- If your buried discharge line is 4", connect directly to the 4" pipe
Test the System
Once installation is complete, test your sump pump to ensure water flows properly through the system.
- Check for leaks at all connection points
- Verify water discharges through Freeze Relief when buried line is blocked
- Ensure vents are clear and functioning properly
Important Considerations
Installations to Avoid
- Do not reduce back down into a discharge line smaller than 3"
- Do not place the last relief port within 6" of grade
- Avoid installing Freeze Relief with vents facing the house
Pro Tips
- The more distance between the Freeze Relief vents and the ground, the better
- Install the top of the Freeze Relief about 4" below elbow for easier installation
- 12" clearance above ground is better than 10", and 10" is better than 8"
