Testing fresh water system in 2015 white hawk 20 MBR. Gauge shows empty after I added approx. 15 gals. Pump kicks on, no leaks found. However system will not pressurize. Unit has been idle for several months. I need help.

Bon Voyage

Check all your drains, check that you aren't filling the water heater, outside shower, toilet, sink, etc for leaks.

If all that is good check your back-flow valve is working.
