- Unplug the primary pump and cut its discharge pipe approximately one foot above the floor.
- Install a check valve on top of the primary pump's discharge pipe, ensuring the arrow on the check valve points upwards to prevent backflow. Tighten the bottom hose clamp.
- Cut a piece of PVC pipe to reach from the bottom of the sump pit to about one foot above the floor.
- Glue the pipe adapter onto this newly cut pipe and then screw it into the backup pump.
- Drill a 1/8-inch hole in the pipe above the backup pump at a 45-degree angle towards the bottom of the sump to prevent water splashing outside the sump pit. This also prevents airlock.
- Lower the backup pump with its PVC pipe attachment to the bottom of the sump pit, next to the main AC pump. Ensure the pumps do not touch each other.
- Attach a Y-connector to the primary pump's discharge pipe.
- Connect the PVC pipe from the backup pump to the Y-connector using a 45-degree elbow.
- Once the assembly is correct, take the pieces apart, prime, and cement all connections. Tighten all hose clamps on the check valves.
