I'm about to get to where I can get into where the line enters the tank. Then I stopped to look for my impact screwdriver and got sidetracked. Had to get a drink of water, comb my hair, then I found something else that I needed to do, then...
.......some of you know how that goes when you get aged (smile). I'll get back to it when I finish shining my shoes.
"What we have here is a failure to communicate", lol.
When the main water line is hooked directly to the pump, I still get no water.
If I blow into that line, I blow air and water out the overflow tube.
So............the problem MUST be inside the tank, like maybe the hose got busted above the water line. Water can flow into the pump, no problem, but
I'm sorry I haven't made myself clear enough. I'm also writing to other individuals.
What you have said is "AIR will back flow to the tank, water will not flow to the pump". Or is that "out of the pump?
This sounds like what has been said several times a check valve gone bad. There IS a check valve somewhere you need to find it if not at the fresh water inlet,just behind where you connect the fresh water hose or output line at the tank.
I don't know about yours but my water tank output is at the bottom of the tank so gravity flow should flow out of the pump inlet if the inlet hose is removed if not check valve or crimped line.

Thanks, Gary. My tank seems to be mounted atop the diesel tank. I don't know how to get to it or to where the water line goes into the tank.
Let me reiterate something: NO VALVES OR ANY SORT ARE INVOLVED.
I finally hooked the main water line DIRECTLY to the pump. Nothing doing! It sucks air and it blows air, so that line is NOT immersed into water anywhere. That is what seems so weird........because if I hook it up correctly and connect a water hose, the tank will fill.......AND......turning it to city water, all the faucets will dispense water.
My '99 TW is mounted on a Freightliner Chassis, and it seems like NOTHING ELSE
has the tank anywhere near this one's configuration. Even the front door TW is different, as best as I can tell.
Anyway, folks from TWO forums and one mailing list, strictly for National RVs, have been able to nail it!
So, bad as I hate to, I guess I'm gonna have to take it to the repair shop. I actually doubt that they will know any more than I have learned (smile).
FALSE ALARM! That little "hole in the wall" didn't allow me to see anything but the tank. Not one line anywhere and I couldn't reach around and feel any line, so I'm back on a dead end street!
It would appear to me that one would have to remove the carpet and cut a hole in the floor to get to the necessary "hot spot".
I may just punch a hole in the tank from my little "peep hole" and run a new line all the way to it. Of course I'd have to string it around the roof and ac units up there a few times and then down through the ceiling and floor .....I'm
kidding, but this is the most complicated thing I have encountered.......so far.
Gary, you wrote: "There IS a check valve somewhere you need to find it if not at the fresh water inlet,just behind where you connect the fresh water hose or output line at the tank".
If there is a check valve "at the tank" might it be that it will let water "in" but not "out"?? That would be the only way that a valve is involved, because of the way I have it hooked up, as mentioned in my previous post. If so, then I stand corrected on the "no valve" remark.
The same line is used for "filling" and for "pumping" it back "out" to the rest of the system.
