WARNING! PUMPSPY SYSTEM TESTS MAY OCCUR AT ANY TIME. THE BACKUP PUMP MAY
CYCLE AT ANY TIME WITHOUT NOTICE.
METHOD 2 (Connecting to existing discharge line) -
See Figure 2
If a separate, dedicated discharge is not desired as in Method
1, the Backup Pump can be tied into the main pump’s discharge
pipe by installing a “Y” connector. Two check valves will be
required.
1. This pump has a 1-1/2 in. NPT discharge.
2. Cut a 3 ft. section of 1-1/2 in. rigid PVC pipe.
Glue 1-1/2 in. pipe to a threaded fitting.
3. Screw pipe from step 2 into pump discharge.
4. Place the pump with the 3 ft. section of PVC pipe 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 pump failure.
5. Attach a check valve (sold separately) to the top of the
discharge pipe. A check valve is required for proper
operation of system.
6. Duplicate the discharge piping arrangement for the
primary AC pump if the existing discharge line has to be
adjusted to accommodate a second pump.
7. Glue a 45º elbow to the pipe on the Backup DC Pump.
Glue a “Y” adapter to the pipe on the main pump, as
shown in illustration for Method 2.
8. Glue a short piece of PVC pipe between the 45º elbow
and the “Y”.
THE CHECK VALVES FOR BOTH PUMPS MUST BE INSTALLED BELOW THE “Y” FITTING!
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 distance.
AFTER PLUMBING IS COMPLETED, FOR BOTH METHODS 1 AND 2:
Install float sensors at least 10” - 12” above bottom of sump pit, making sure that the sensors are at least 1” - 2” higher than the
normal “on” level for main pump.
Make sure power wires and hose clamp ends do not interfere with float switches or pump operation. Failure to position properly
may cause improper operation. Position all switches so they will not interfere with any portion of the plumbing, wiring, or sump
pit.
BACK-UP PUMP OPERATION:
1. The backup pump will turn on when either the bottom or top float sensor rises and is engaged for 3 seconds.
2. The backup pump will keep running for 10 seconds after the float sensor drops.
3. Your PumpSpy
™
system activates and tests the backup pump and battery health at least 3 times per week.
NOTICE
This pump was not designed to handle salt water, brine, laundry
discharge, water softener discharge or any other application that
may contain caustic chemicals. Damag to the pump may occur
and will void the pump’s warranty.
