Going from city water to potable water in 2516G

[NoTrumpAce]

We are going to use the potable (onboard) water source for the first time in a couple of weeks in our 2018 model 2516G. We have used campground water sources in the past. I have reviewed the owners manual and understand the function of the internal pressure pump to provide water pressure for onboard water. Is there a valve that has to be turned to switch sources from an external water source to the onboard water? Thanks in advance for a response.

No valve just turn on your pump make sure you have water in your fw tank

If this is the very first time using your on board fresh water system, you might want to test it before you’re out camping.

Fill the tank until it overflows from the overflow tube. Turn on the pump....it should prime itself then stop and be silent. Next, try the taps at the bathroom, kitchen, outside and shower. This gives the pump a workout since being installed. You may hear the pump pulsing....that’s normal.

Try it out a few times. Drain the water tank from the fresh water drain tap. Check your indicators at various points of the test. When you’ve emptied the tank, see if your indicators show empty.
