The water hose fitting at the top is where you attach your water line. The white lever on the right is what switches between city water (direct to the RV) and filling the water tank. In its current horizontal position, it will provide direct city water to the RV. In the vertical position, it will fill the fresh water tank. You only want to do this will you are monitoring the fill to make sure it doesn’t overflow.
The two switches on the left are the low point drains to drain any water out of the lines when you are done camping or to winterize. They are in the closed position and that’s where they need to be.
The water hose fitting at the bottom is to flush the black tank when you are dumping it. Also need to monitor anytime you are flushing the black tank to make sure it doesn’t overfill.
