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.
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 separately) will be necessary.
Smaller diameter piping will reduce pump flow,
rate and performance.

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, 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.
Method 2
If a separate, dedicated discharge is not
possible as in Method 1, the ESP25 pump
can be tied in to the primary pump's
discharge pipe by installing a "Y" connector.
Two check valves will be required.
1. Locate the ESP25 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.
