An isolation valve should be installed at both
the suction and discharge sides of the pump.
This will allow you to remove the pump for
preventative maintenance or repair without the
need to drain your system.

If pump is not in a flooded suction condition,
install either a foot valve or system check valve
to insure pump volute is flooded for priming.
•
In order to provide pump flow rate control,
a control valve should be installed in the
