Cut the Discharge Pipe (Methods B & C)
 Be prepared for water to leak from the coupling or piping
when disassembling or cutting the discharge pipe. Protect
system components, tools, and supplies from getting wet. Dry
any work areas that get wet immediately.
1. Put the newly assembled dual pump back-up system into the
sump pit.
The discharge pipe now overlaps the discharge pipe that leads
outside.
2. Mark the discharge pipe where it should be cut.
Be sure to leave a 1/4" air gap between the ends of the pipes.
This gap will absorb the noise from vibration and allow for
flexibility.
3. Make the third cut as shown in Figure 7.

Trial Assembly (Methods B & C)
1. Connect the pump discharge pipe to the exterior discharge
pipe with a rubber coupling and clamps.
Do not tighten the clamps until all the final adjustments are
complete.
2. Make the final adjustments. Make sure the pumps and the
switches do not interfere with each other. Make sure there is
plenty of room for the float switches to either swing or to
move up and down from their "off" to their "on" positions.

Preliminary Assembly (Methods B & C)
1. Mark the pipe and fittings at all connections with a pencil.
These marks will be used as a reassembly guide when joining
with primer and cement to be sure everything is still in the
right place and nothing has moved.
2. Loosen the rubber coupling and clamp connection.
3. Carefully pull the dual pump back-up system out of the pit.
4. Take the tee assembly off the primary discharge pipe.
Do not unscrew any of the thread seal taped fittings.
5. Prepare all unconnected PVC pipe ends with primer.
6. Apply cement to these PVC fittings where indicated by the
marks.
Final Assembly (Method A)
1. Position the back-up pump into the pit.
2. Complete the back-up pump separate discharge line.
3. Make the final float switch adjustments, tighten the mounting
clamp, and secure wires as needed.
Final Assembly (Methods B & C)
1. Position the dual pump back-up system back into the pit.
2. Install and tighten the rubber coupling and clamps.
3. Make the final float switch adjustments, tighten the mounting
clamp, and secure wires as needed.
