Installation
Installation of this unit may take
severalhours.Beforedisablingyour
main pump, have ready an appropriate means of evacuating the
sump.
1. Turn power to main pump off.
2. Pump must be instaled using 1-1/4 in. or 1-1/2 in. rigid
PVC piping.
Pump Installation
The back-up pump can be installed with a separate dedicated
discharge line (Method 1), or tied into an existing sump pump
line (Method 2).
UnplugtheexistingACpump.Failure
to follow this warning COULD result in
fatal electric shock.
1. Verify that the existing AC pump is in good working
order. If the AC pump is questionable, it is typically
recommended that the unit be replaced with a 1/3 HP or
1/2 HP pump.
2. Remove any silt or accumulated debris from the sump
pit and surrounding area.
Method 1 (Preferred)
1. Locate the back-up pump on a solid, level surface in
the sump pit. Do not place the pump on a loose or
sandy surface. Small stones or sand may damage the
pump resulting in potential pump failure.
2. This pump has a 1-1/2 in. NPT discharge. If a 1-1/4 in.
discharge pipe is desired, an adapter (not included) will
be necessary. Smaller diameter piping will reduce pump
flow, rate and performance.
3. Cut a 4 ft. section of 1-1/4 in. or 1-1/2 in. diameter rigid
PVC pipe. Cement 1-1/4 in. pipe to a threaded fitting.
Cement 1-1/4 in. pipe into pipe coupling. Attach 1-1/4 in.
pipe section to the back-up pump discharge adapter.
4. Screw on to pump discharge.

5. Place the pump with the 4 ft. section of PVC pipe on a
solid, level surface in the sump pit on an elevated
surface.
6. Attach a rubber check valve (sold separately) to the top
of the discharge pipe. This will allow the pump or check
valve to be removed easily for servicing.
NOTE: Check valves can be placed directly in the pump
discharge if desired. However, for ease of disassembly, it is
recommended that check valves be placed above the sump
as shown in Figure 1.
The remainder of the discharge pipe installation will vary
depending on individual circumstances. Using sound
plumbing practices, route the discharge pipe to an exterior
wall by the shortest path. Keep turns to a minimum because
they reduce flow output of the pump. The pipe that exits the
building structure should be sloped downward so that water
will not freeze in the pipe.
When installing the separate discharge pipe, drill through the
outside wall with appropriate drilling equipment. Seal the hole
to prevent water from entering.
