My motorhome has been sitting for a while and I was going to add some water into the toilet bowl so it doesn't go dry. I turned on the pump switch to pressurized the line and it just kept running longer than usual. I turned it off and did a walk around looking for water under the coach. Found water dripping out of the wet bay. Opened the door and there was water dripping out behind were you attach the hose. Turned the pump on again and the drip turned into a steady stream. In the picture I attached it seems to be coming out between the white part and the back of the board were the hose fitting is, not the pex 90*. Is this part the back-flow valve? Or is it just a check valve?

The water inlet is usually a check valve. This permits you to pump water from the water tanks while not being pumped out of the inlet or water hook up. Looks like you have access from the pictures. Pull the leaking part out. Take a picture of it and you should be able to find the replacement, with a picture search. My inlet valve got replaced here.

My Barth is 37 years old. These parts have not changed much over the years.
