What is a Dual Fresh Water System?
A… Dual Fresh Water System… …provides two completely independent fresh water supply systems.
Each system has its own tank, fill, vent and pick up leading to a dual filter system. If there is ever any contamination or delivery problem in one system, then a turn of valves puts the second system on line quickly.
* Turn both tanks on,
* Isolate either one tank from the other, or
* Turn both tanks off!
