Introduction

The Basement Watchdog Special backup sump
pump system is battery-operated. It is designed as
an emergency backup system to support your main
AC sump pump, and it will automatically begin
pumping any time the float switch is activated by
rising water. Should any malfunction or emergency
occur that involves the sump pump, the battery, or
the AC power, the Basement Watchdog system will
sound an alarm. A light on the display panel of the
control unit will indicate the cause of the alarm
and the corrective action.

For added reliability, the float switch has, not
one, but two floats. Should one float fail to
operate, the second float automatically activates
the pump.

The Basement Watchdog Special Sump Pump
System includes:

• A control unit with a dual float switch, a
battery fluid level sensor, battery cables, and a
20 amp fuse

• A pump with a 1½” PVC pipe adapter

• A plastic wire tie for mounting the float switch

• A battery box

• A battery charger

• A battery cap with a hole to accommodate the
fluid sensor

You will also need to supply:

• A Basement Watchdog Big Standby Battery
(30HDC140S or BW-30F) or Basement
Watchdog Maintenance Free (AGM) Standby
Battery (BW-27AGM).

DO NOT use an automotive battery with
this system
DO NOT use a Basement Watchdog Emergency
Standby Battery (24EP6 or BW-24F) with this
system. It will not run the pump as long as the
Big or Maintenance Free (AGM) Standby Battery

• 1½” rigid PVC pipe and fittings

• Six (6) quarts of 1.265 specific gravity battery
acid (30HDC140S and BW-30F). Battery fluid is
not needed if using the Basement Watchdog
Maintenance Free (AGM) Standby Battery.

For narrow sump pits you will need some
additional parts:

• An “L” bracket at least six (6) inches long
(preferably one that will not rust)

• Two (2) stainless steel hose clamps

• One (1) stainless steel screw (#8-32 x 3/4”), a
matching washer & nut

Installation Instructions

There are two basic methods that can be used to
install the pump, a direct discharge to the
outside of the building, or a connection to an
existing discharge pipe. The same two options
apply in very narrow sump pits where the backup
pump must be mounted above the main pump.

Use a pit that conforms to all local codes, and
check the code to see if a gate valve or ball valve
is required.

Whenever possible, install your Basement
Watchdog backup pump with a direct discharge
to the outdoors. By using this method, there will
always be an outlet for the water from the sump.
During times of very heavy rain, many storm
sewers fill up. If your pump is trying to
discharge water into a full sewer, there is
nowhere for the water to go. By discharging
directly outdoors, there is always an outlet for
the water that is pumped out of the sump. For
this method, you will need to drill a hole through
a floor joist or the foundation from the basement
to the outside of the house.

If the direct discharge method is not possible or
convenient, the Basement Watchdog pump can
be connected to the same line as your main AC
sump pump by installing a “Y” connector and
two (2) check valves.

In most cases, the backup pump will fit next to
the main AC pump in the sump pit. In very
narrow pits, the backup pump can be mounted
above the main AC pump. Try to fit the backup
pump on the floor of the sump first. Make sure
there is enough room so that the backup pump
and the main pump do not touch each other.

Select the installation method that will best suit
your needs from the diagrams at the right. Full
instructions for each installation method are
provided on the following pages.

Installation will take a couple hours.

BUILDING (Diagram A)

DANGER

!

Unplug the main AC pump when installing
the backup pump to avoid electric shock.
Failure to do so could cause serious injury
or death.

1. Cut a piece of 1½” rigid PVC pipe long
enough to reach from the bottom of the
sump pit to one (1) foot above the floor.
Prime and cement it to the 1½” pipe adapter,
then screw the adapter into the pump.

2. Secure the pump wire so that the plug on the
end will not fall into the sump. Attach the
wire to the pipe with a piece of tape.

3. Place the pump with the PVC pipe attachment
on the bottom of the sump floor next to the
main AC pump. The pumps should not touch
each other. Do not mount the pump to any
existing pipes; it should be placed on the

floor of the sump. A brick should be placed
under the pump if there are rocks or other
debris on the sump floor that may clog the
pump.

4. Attach a union or a check valve to the top of
the 1½” pipe. This will allow the pump to be
removed easily, should the need arise.

The path of the rest of the pipe and the details
of each installation will vary. Using sound
plumbing practices, route the discharge pipe to
an exterior wall via the shortest path with the
fewest turns. More turns will reduce the
pumping capacity. The pipe section exiting the
building should be on a downward slope so that
the water in the pipe will exit outside instead of
returning to the sump pit. Be sure to seal the
hole in the wall where the pipe exits, and prime
and cement or clamp all connections securely to
prevent leaking. (No check valve is needed with
this method of installation as long as you use
less than 20 feet

If you use more than a total of 20 feet
pipe in the installation (including vertical
and horizontal runs), install a check valve in

of pipe.)

CAUTION

place of the union. Make sure it is installed
with the arrow pointing up, or it will not
prevent the backflow of water. When a check
valve is used, a 1/8” hole must be drilled in
the PVC pipe above the Basement Watchdog
pump. Drill the hole at a 45° angle toward
the bottom of the sump to avoid splashing
water outside the sump pit. Make sure the
hole is above the water line and below the
check valve. If a hole is not drilled above the
pump, an air lock may prevent the pump
from operating.

Depending on your installation requirements, PVC
pipe lengths will vary. Cut the pipes and assemble
them as shown in photo #7. Do not cement them

together until you are sure they are cut to the
correct lengths. It is important to keep the

discharge pipes on both pumps parallel to each
other, so that the pumps remain flat on the floor
of the sump. More detailed instructions follow.

valve. Drill the hole at a 45º angle toward
the bottom of the sump to avoid splashing
water outside the sump pit. If a 1/8” hole is
not drilled in the pipe above the pump, an air
lock may prevent the pump from operating.

4. If there is no check valve on the discharge
pipe of the main AC pump, one must be
installed at this time. Cut the discharge pipe
approximately one (1) foot above the floor.
Install a check valve on the top of the pipe
and tighten the bottom hose clamp. Now
prime and cement a small piece of 1½” PVC
pipe to the bottom of a “Y” connector. Prime
and cement the top of the “Y” assembly to the
discharge pipe with the “Y” extension facing
down toward the backup pump. Now connect
the bottom of the assembly to the check valve
and tighten the hose clamp.

CAUTION

Failure to install a check valve between the “Y”
connector and the Main AC pump will cause the
backup system to not operate properly. A 1/8”
hole must also be drilled in the PVC pipe above
the Main AC pump.

5. Secure the pump wire so that the plug on the
end will not fall into the sump. Attach the
wire to the pipe with a piece of tape.

6. Place the pump with the PVC pipe attachment
on the bottom of the sump floor next to the
main AC pump. The pumps should not touch
each other. Do not mount the pump to any
existing pipes; it should be placed on the floor
of the sump. A brick should be placed under
the pump if there are rocks or other debris on
the sump floor that may clog the pump.

7. Connect a piece of 1½” PVC pipe above
the check valve of the Basement
Watchdog pump, and attach a 45°
elbow to that pipe. Extend another
piece of pipe to reach from the 45°
elbow to the “Y” connector on the
other pipe.

8. Prime and cement all pipe connections
securely to prevent leaking, and
tighten all the hose clamps.
