Autoflush System


Your Rainman watermaker is a very robust piece of equipment, but caring for certain aspects will prolong the useable life. If seawater is left for too long in your watermaker, planktonic organisms will die and rot. This can eventually damage the reverse osmosis (RO) membranes in your watermaker.

The Autoflush System incorporates a solid state timer, a motorised valve, and an activated carbon filter to allow your boat’s fresh water supply to push fresh water from your boat’s tanks through your watermaker for a few minutes every seven days. The one button programmable timer can be set between two and eight minutes flush cycle duration, depending on how strong your boat’s water pump is. The activated carbon filter will neutralise chlorine that may be in your tank from municipal water sources.
