Leaking Connections

Retighten fittings . When tightening any of the fittings in any one pump circuit, the
corresponding fittings in the other circuits must be tightened by an equal number
of turns . This ensures that the spacing within the pump circuits remains equal .
If tightening does not stop the leak then use the controller to make that pump
unavailable, isolate the pump, completely loosen the fitting, clean the threads
and then retighten . Return the pump to active status .
