Installing A Big Flo Diaphragm Valve
Disconnect, lock out, and tag power at the panel before servicing the pump
When servicing equipment, use non-sparking tools and use caution when removing or
installing equipment to avoid generating a spark.
The installation described herein is for a single pump system (reference Figure 8). If two
pumps are to be installed in tandem, contact your service representative for instructions for
your specific system.
1. Since the leak detector only checks for leaks down stream from itself it should be installed as close to the
pump as possible while still maintaining clearance for the removal of the pump check valve housing.
2. Install the “Big-Flo” Diaphragm Valve per the instructions included with the “Big-Flo” Diaphragm Valve.
3. Install the vent line from the FXV to the 1/4 NPT port in the six inch flange using tubing and fittings supplied
with the leak detector.
4. Test the installation per the instructions included with the “Big-Flo” Diaphragm Valve.
Figure 8. Installing A Big Flo Diaphragm Valve
Note: If Big Flo valve is installed in separate
sump, a passage way must be run between the
two sumps. The FX vent line can be easily routed
back to the tank through this passage way.
