I have a fill inlet for potable water and another input for pressurized water if that service is available. None of my documentation explains how the two systems interact and or connect. A short tutorial would be very helpful.
The potable water is a 26 gallon tank fillable on the side with the awning the water pump needs to be turned on. The pressure city water connection is on the opposite side the pump needs to be turned off when using that I have the same model pop up
The fill inlet is used to put potable water in your fresh water tank. You turn on your 12 volt water pump to pull water out of the fresh water tank and pressurize it for use in the trailer when you don't have a connection to campground water.
With the campground water inlet, pressure from the campground water system pushes water through the same pipes to the same outlets/faucets/etc. An anti-reversing check valve in the water pump should keep pressurized campground water from filling your freshwater tank.
