main pump, have ready an appropriate
means of evacuating the sump.
1. Turn power to main pump off.
2. Pump must be installed using 1-1/4"
or 1-1/2" rigid PVC piping.

PUMP INSTALLATION
The ESP25 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, Page 3).

CORRECT
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. Place 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 (sold

6. Attach a rubber check valve (sold
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, page 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.
