Never allow other items that discharge into the sump pit to be unsecured. Unsecured items such as garden hoses, laundry hoses
and other medium used to discharge water may interfere with the NexPump pumps or sensors. Be sure to secure all items that may
be used to discharge water into the sump pit and verify that secured items will not interfere will any NexPump operations.
Installation Procedures
Installing the NexPump does require some plumbing expertise. You can use the installation diagrams at the end of this document
as a reference for proper installation. For a Dual Pump NexPump System, separate discharges are recommended for maximum
discharge rates and multiple output paths. If a Dual Pump NexPump System is installed as a backup, then you can use a WYE,
however install one NexPump Pump on the straight through of the WYE and your normal electric pump on the 45 degree of the
WYE. The remaining NexPump Pump should be installed as a separate discharge. You can install all the pumps in a multiple wye
configuration, however this type of installation may reduce the total discharge capacity about fifteen (15%) percent at high
discharge rates.
Points for Proper Installation
Tighten hose clamps on check valves if applicable.
Tighten pump adapters securely.
Install separate discharges for maximum discharge rate.
Make sure the RED filter screen is securely attached to each pump.
For very narrow sump pits, pumps can be stacked on top of each other. Pump 1 must be the lowest pump.
IMPORTANT: When using a check valve, a small 1/8” hole must be drilled in the vertical discharge pipe of each pump. DO
NOT DRILL INTO THE PUMP OR THE ELBOW. The hole should be drilled at a 45 degree downward angle to prevent water
spraying upwards and position the hole about 2” above the top of the elbow.
IMPORTANT: Ai Turbo NexPump. Pump 1 must be the pump with the RED WIRE LOOM.
REVIEW ALL SAFETY PRECAUTIONS AND INSTRUCTIONS BEFORE PROCEEDING!
Finishing Installation
Step 1: Positioning the Sensors
Sensor 1 is the main sensor and will operate the pump(s) when the water rises above the sensor. The gray sensor should be used
for Sensor 1. Sensor 2 does not operate exactly like Sensor 1 however, functions as a backup and high water alarm. (See Sensor
Operations). The white sensor should be used for Sensor 2. Attach the sensors to any discharge pipe securely with the supplied
stainless steel clamps (float side down, sensor cable up, mounting bracket up, remove any shipping tape). Float on each sensor
should move freely up and down.
Position the sensors as described below.
Sensor 1 (Left Sensor Receptacle)
NexPump in Backup Mode:
Position Sensor 1 approximately 4 - 6 inches above the activation level of the main pump. If not, the NexPump may show the
pumps have been activated prematurely.
NexPump in Primary Mode (only sump pump):
Position Sensor 1 approximately 2 - 4 inches above the pumps.
NexPump in Primary Mode (with electric sump pump):
Position Sensor 1 above the level of the NexPump pumps and below the level that the AC pump will turn on.
Sensor 2 (Right Sensor Receptacle)
Sensor 2 is used as a backup and alert for high water. When activated the NexPump will begin operation in a special emergency
mode and with the ‘Auto Notification’ feature will alert immediately. Position Sensor 2 about six inches above all other trigger
