We just completed our first voyage on our 2017 Quantum. We were dry camping and using water from our fresh water holding tank. Sooner than expected we seemed to run out of water on our 30 gallon tank. The water pump was making the usual noise but water flow came to a halt.

Since our water tank full indicator lights were not even hooked up at the factory (GRRRR) I visually checked the holding tank water level. The tank is about 5 inches tall and we still had about 2 inches of water depth in the tank. And yes my rig was level.

Once we got home I filled the holding tank back to full capacity and now the water system works as it should.

So my question is - how much water should be left in the tank before it is "empty"? I can see where a bit of water might not be accessible for the pump to get to but 2 inches of water seems very unacceptable. 2 Inches of water is probably about 30% of the tanks overall capacity.

I will be taking this issue back to the dealer along with many other issues (GRRRR) but wanted to get an idea for what others have experienced on the ability to use all water from the holding tank.

Can I expect to get every drop of water or is there always a bit left that is not accessible to the pump?
