1. Fresh Water Flush, how does it work?
A FWF runs automatically when the watermaker is stopped, it automatically re-flushes every 7 days.
The FWF uses the ship's on-board water system to supply fresh water through the FWF, Carbon Filter, which removes any chlorine, and then flushes the watermaker.

2. Ultra Violet Sterilizer (UV) do I need it?
Yes. A UV is recommended if the feed water (intake) is from a harbor or polluted source.

The R.O. Membrane rejects bacteria and virus, yet should biological migration occur across the membrane then the U.V. Sterilizer will destroy 99.9 % of any biological intrusion into the product water.

4. Is the booster pump self-priming and what size is it?
No. Although the High Pressure Pump assists initial water draw, the Booster Pump should be mounted below water level for best performance.
Our Booster Pumps are sized for maximum allowable pressure in order to gain maximum prefilter element life. This saves time and money for the owner.

5. Do I need a Plankton Filter or a Multi Media Filter?
Both filters achieve the same results in prolonging the life of the prefilter elements. The Multi Media Filter provides longer intervals between maintenance.
Either are highly recommended for harbor or shallow water operation, as well as fishing grounds and areas such as the Pacific North West where plankton levels are high.
