Re: A54 seawater pump for anchor washing

Mark & Debbie Mueller
 

The non-return valves or check valves are important.  These valves prevent air from being pulled backward through a non–operating piece of equipment into the common seawater distribution manifold.  Air will dramatically affect the performance of the Dessalator and negatively impact the refrigeration and other systems.  If it continues over a longer period of time the air will cause the same effect as cavitation on the metal pump impellers.  These valves are important and need to be in place.
