Step-by-Step Water Powered Sump Pump Installation Guide
Here’s how to install your emergency backup sump pump:
1. Mount the Backup Pump
Screw two 3-foot-long 2×3 cleats into the wall above your existing sump pump using 3-inch screws. Mount the backup pump on the cleats and set the float switch slightly higher than the primary pump’s float.
2. Connect to the Water Supply
Cut into a nearby cold water line using a tubing cutter. Install a ¾-inch copper pipe running down to the backup pump’s control valve. Solder the joints using a propane torch and lead-free solder.
3. Prep the Existing Discharge Line
Turn off and unplug your primary sump pump. Then loosen the check valve on the discharge pipe to drain any water before cutting into the line.
4. Install a New PVC Discharge Pipe
Connect a 1½-inch PVC pipe from the backup pump to the existing discharge line. Apply primer and cement to all joints for a leak-free connection. Add a new check valve.
5. Flush the System
Take apart the backflow preventer and open the water valve. Flush any debris into a bucket before sealing the system.
6. Test the Pumps
Refill the sump pit with water. Plug in your primary sump pump and allow it to activate. Then unplug it and raise the float on the backup pump to ensure it activates correctly.
Installation Tips for Success
- Use flexible fittings for tight spots.
- Always flush pipes after soldering to avoid clogs.
- Double-check all seals to prevent leaks.
- Allow cement to cure fully before testing.
