Re: A54 seawater pump for anchor washing


Mark is is absolutely correct, and this applies to the one-way valve on the SM, 54, & 55 AC need it and it needs to work. Also, if you happen to replace the diaphragm anchor wash pump with something else (I know a few of you have), you should ensure that there is no backflow, or you will get air in the Dessalator system.

It is almost always to your peril when you decide that something Amel added, "is not necessary." Sometimes this can be learned the hard way, which is also the costly way.

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.
