The pump draws 2.20ah...so for less than 5 minutes, this is a very miniscule draw.ScottG said:So am I interpreting correctly that "siphon mode" does not require the pump or any power? Do you have to place your jug up high and and actually start a siphon, or can you just pour through the length of hose (assuming it is also connected to the jug).

From a jug, no. From city water, yes.ScottG said:So back to my question...
Is there any way to fill the FW tank without running the pump (regardless of the reason why someone would want to do so)?
Just curious more than anything. I have no desire to trade my 2015. :-)

But not without using the pump.Sharon_is_SAM said:You can fill the fresh water tank from a jug/bucket.

2021 was the first model year for the Nautilus in the 320 and it is a different model than the one used in the 400.Denny16 said:The Nautilus system has been out since model year 2020, produced back in 2019. At first there were many discussions around how to use it. But for the last year, this has slacked off to the odd, occasional question like this one.I also believe, thst if the supply jug is higher than the Nautilus connection point, you can start the pump to get the water going shut the pump off, and it will continue to siphon the water in.Cheers

@ScottG, I will happily test this for everyone, given I get my hands on the hardware, and that winter ends. Its -20 something right now. <grin>ScottG said:But not without using the pump.Sharon_is_SAM said:You can fill the fresh water tank from a jug/bucket.

#1 appears to cover what jkjenn described above--you don't need the pump if you have a pressurized water supply.
This isn't just an academic question. When dry-camping, I top up my FW tank by pouring water from a 6 gallon jug into the FW fill port. While this requires a bit of huffing and puffing, it does not require a pressurized water supply or the use of any battery. I'm conservative with my power and I like having simple options with few potential points of failure. I suspect I am not alone in this regard.
I wonder if a jug with a spigot and hose connector set just above the level of the Nautilus could "power fill" the FW tank just by force of gravity. It seems this would work, provided there are no valves in the fill circuit that require a certain minimum pressure to open.
@DougWW, I think you may have to be the one to test this out! ;-)
