Pump & Pipe
Installation Instructions
(Hookup to Existing Discharge Pipe)
If the direct discharge method (Method
A) is not possible, the Emergency Sump
Pump System can be hooked up to the
same pipe as your AC sump pump by
installing a "Y" connector and two check
valves.
Check your local plumbing codes.
Some municipalities prohibit the dis-
charge of sump water into the sewer
system.
If you have a sump pit wide enough to
place the backup pump next to the main
pump, use Method B. If your sump pit is
too narrow, the pump may be mounted
above the main pump. In this instance
use the instructions for Method Bb.
METHOD B: HOOKUP TO AN
EXISTING DISCHARGE PIPE
(Diagram B)
1. Cut a four-foot (4’) piece of 1 1 / 2 "
rigid PVC pipe and cement it to the
threaded fitting that is attached to
the elbow on the pump.
2. (a) Install a check valve on the PVC
pipe attached to the Emergency
sump pump.
(b) IMPORTANT:
WHEN A CHECK VALVE IS USED,
DRILL A
1 / 8 " HOLE IN THE 1 1 / 2 "
PVC PIPE THREE INCHES (3")
ABOVE THE CONNECTION TO
THE EMERGENCY PUMP. Drill the
hole at a 45˚ angle toward the bot-
tom of the sump to avoid splashing
water outside the sump pit. If a
1 / 8 "
hole is not drilled above the pump,
an air lock may prevent the pump
from pumping.
3. If there is no check valve on the
pipe of the main AC pump, one
must be installed at this time. Then
install a "Y" connector above the
check valve on the discharge pipe
for the main AC pump.
4. 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.
5. Place the pump with the 4’ PVC
pipe attachment on the bottom of
the sump floor, next to the main AC
pump. Do not mount the pump to
any existing pipes...it should be
placed on the floor of the sump. A
brick may be placed under the
pump if there are rocks or other
debris on the sump floor.
6. Connect a 1 1 / 2 " diameter discharge
pipe above the check valve of the
Emergency sump pump, and at-
tach a 45˚ elbow to that pipe. Extend
another piece of pipe to reach the "Y"
connector you have inserted above
the check valve on the discharge
pipe of the main pump.
7. Cement or clamp all connections
securely to prevent leaking.
