2022 Cirrus 820 fresh water tank question

bingle

Not sure is this thread is still active. Just bought a 2022 Cirrus 820, first trip is tomorrow. While filling the fresh tank and watching the sensor levels I heard a strange sound and found a huge over flow draining out of the bed of my truck. I am accustomed to filling the tank on my other rv’s and waiting for it to come out of the vent. However it appears there is not a vent anywhere on the exterior of the unit. So my question is what happened, is there a vent on top of tank? Did I damage anything? Kinda frustrating, the levels showed 3/4 full not full. How do I handle this going forward?

The 2022 820 includes the Nautilus Water Control System.
Rigs without a Nautilus generally have a Gravity Fill Port (water hose is not connected to rig) and those gravity ports have a tank vent line at/near the fill port.

Nautilus uses a 'power fill' method, city water hose is connected to the rig, city water pressure (power) fills the tank. Of course the fresh tank still needs a vent, on the TAB 320/360/400 the vent is located on the tank top and vents down below the trailer. If the tank is over filled then water rushes out of the vent line. The Cirrus must also have that style of vent - - - I do not know the specific location of a Cirrus tank or the vent line/tube output location but that is the water coming out of the truck cargo bed.

As for the LED tank monitor system, now used by nüCamp, it is a really bad product and rarely correctly displays any of the tank levels. Don't trust the monitor . . .
