[C320-list] Priming Fresh Water Pump

[John Morrison]

Fill the aft tank and open the aft feed valve. The water level will be higher than the pump and should readily prime.

Maybe there is dirt in the check valves or diaphragm.  Maybe you have a line blockage?  You do not want easy priming tricks you want to determine why it does not self prime.
