PUMP INSTALLATION
Installation of this unit may take
several hours. Before disabling your
main pump, have ready an appropriate
means of evacuating the sump.
1. Turn power to main pump off.
2. Pump must be installed using 11/4”
or 11/2” rigid PVC piping.
PUMP INSTALLATION
The ESP45 can be installed as a back
up system with a separate dedicated
discharge line (Method 1), or tied into
an existing sump pump line (Method 2).
Unplug the existing AC pump. Failure to
follow this warning could result in fatal
electrical 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 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 ESP45 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 11/2” NPT
discharge. If a 11/4” discharge pipe
is desired, an adapter (not included)
will be necessary. Smaller diameter
piping will reduce pump flow, rate
and performance.
3. A check valve will be required in
the discharge line of both the Main
AC pump and the ESP45 pump
to prevent recirculation of water
into the sump pit. System will not
function without two check valves.
4. Cut a 4’ section of 11/4" or 11/2"
diameter rigid PVC pipe. Cement
11/4" pipe to a threaded fitting.
Cement 11/4" pipe into pipe
coupling. Attach 11/4" pipe section
to the ESP45 discharge adapter.
5. Screw on to pump discharge.
Be careful not to strip or cross thread
plastic fi ttings or check valves. Flex hose is
not recommended. Rigid PVC or metal pipe
is required for a permanent installation.
6. Place the pump with the 4’ section of
PVC pipe on a solid, level surface in
the sump pit on an elevated surface.
7. 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.
8. Check valve is required for effective
operation of system.
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 2.
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 fl ow 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.
Method 2
If a separate, dedicated discharge
is not possible as in Method 1, the
ESP45 pump can be tied in to the AC-
operated pump’s discharge pipe by
installing a “Y” connector. Two check
valves will be required.
1. Locate the ESP45 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 11/2” NPT discharge.
If a 11/4” discharge pipe is desired,
an adapter (not included) will be
necessary. Smaller diameter piping
will reduce pump flow, rate and
performance.
3. A check valve will be required in the
discharge line of both the Main AC
pump and the ESP45 pump to prevent
recirculation of water into the sump
pit. System will not function without
two check valves.
4. Cut a 4’ section of 11/4" or 11/2"
diameter rigid PVC pipe. Cement
11/2" pipe to a threaded fitting.
Cement 11/4" pipe into pipe coupling.
Attach 11/4" pipe section to the
ESP45 discharge adapter.
5. Screw on to pump discharge.
