Review SECTION 6 and 6.1 (Warnings and Cautions) prior to installation
Reminders of best practice
Fit a valve to isolate the tank
If the suction line is quite long fit another valve close by the pump
Non Return Valve in suction line recommended
Avoid pipework which could trap air
In this example the water level is above the
pump inlet but the water cannot flow freely into
the pump.
Potential air trap
