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 in. -12 in. above bottom of sump pit so that the sensors are higher than the normal “on”
level for main pump.
Make sure power wires and hose clamp ends do not interfere with float switch, pump inlet, or main pump operation. Failure to
position properly may cause improper operation. Position the float switch so that it 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.
2. The backup pump will keep running for 10 seconds after the float sensor drops.
3. PumpSpy
™
will remotely activate the backup pump during system tests at least 3 times per week.
