There was water everywhere this morning. Went to put some water in the tank to find out what's leaking. I am not getting any
water to the fill valve. Tomorrow I will bypass and try and put the water in by where the fill valve was. I thought that was the problem
and I put a ball valve in place of the fill valve. Something is blocking the water from the fill hose to the fill valve. Any ideas.
Check to see if your back flow preventer (water check valve) has failed. Depending on the coach and if you have a hose reel or not will determine where the factory hid it. Ours is in the fitting where the water hose connects to the coach as we don't have a hose reel. Some coaches with the hose reel have this check valve located where the hose comes off the reel and enters the coach. I have seen a few that are hid in the piping behind the vanity cover in your utility bay.

Your year should have a 12 volt electric fill valve it us behind the blue accumulation tank. On my 99 270 it was a manual valve under the sink in the bathroom.
Here it is on a 99 320. The blue thing to the right is the accumulator tank.

The OP knows where his fill valve is located. He replaced the electric fill valve with a ball valve. See original post.
He thinks he has a blockage of some kind between the hose connection and the fill valve.
I'm betting Mike has hit it on the head. Reply #1
Photo below shows the backflow preventer location on our coach:
I'm +1* on the back flow preventor valve being stuck.

In most cases, the fresh water fill backflow preventer valve will be similar to the one in video below:

I'm sure you are right it's the backflow preventer. I have bypassed the whole thing and now can fill the tank. The leak is a blown
plastic line. Not sure which one is blown but I have to fix a pvc fitting I broke first.
The leak is a blown cold water line for the kitchen sink. I have isolated it and we can live without it on this trip. I will pull a new
one in when I get home. I will change the backflow preventer also when I get home. What I have done to fill the tank I would
probably leave it if it was on the left side of the coach.
I still not sure where my backflow preventer is. My line isn't up like yours Chuck its down low and I haven't aquatically seen the
backflow preventer I hope it's not as Mike said hidden in the wall. Oh I have a reel. I had to seal off my fill hose and I thought
why isn't there a check valve, so now I know I just have to find it.
The backflow preventer on our coach never worked. Water was always dribbling out of the hose when we were going down the road. For a while I kept a big towel in the bay to soak up the water. Then somebody told me where to find the valve. I removed it, cleaned a bunch of trash out of it, put it back in place. Still didn't stop the water dribble. So I removed it again, ripped the guts out, and put the "carcass" back in place. Installed a 1/4 turn plastic push-connect valve in the water line between the hose reel and the old preventer valve. Open the valve to fill - close the valve. Never leaked again.
PROBLEM SOLVED. :thumbsup:
You can see the valve in the photo I posted up above (Reply #4). White valve right above the hose reel.
Ours was the latter (in a 2003), which required opening up the utility bay back wall. I believe Jeff and Carol's was in the water pump bay down low behind the manabloc cover (in a 2002).
It's a fairly inconspicuous little bugger.
I put a ball valve on the end of the hose too, that why I never worried about it, now I have too.
On my 1997 U295 40', it has an inspection port on the side of the wet bay, that allowed me to get at the back flow preventer to replace.. It was attached to the water inlet, mounted on the wet bay wall.
