Fresh water tank not filling

2000 Excella
When filling fresh water the water pours out from all over the top of the tank and does not go into the tank. The fill tube looks good at fill point

So you are saying that you are standing outside of the trailer, you open the FW fill port, and say, insert a garden hose and turn on the water. You then go inside the trailer and see water pouring out all over the top of the tank, but not going into it?

If that is what you are describing, how is water getting out of the fill tube and "all over the top of the tank?"

So, assuming that the fill port on the outside fo the trailer is in good condition (they are often made of plastic and crack with age), and that the tube from the fill port down to the tank is in good shape with solid connections on each end, then next culprit I would look for is usually there are one or two "breather" tubes that also go from the top of the tank up to the fill port. This breather is to allow air to escape the tank while you are putting water into it. If someone has removed the breather hose altogether, then I could imagine water coming up through the hole on the tank (or just pouring down from the fill port), or if they only disconnected it at the bottom, then water could be coming down the breather and pouring all over the top of the tank as described.

If you are trying to fill the FW tank by, for example, dumping a bucket of water into the fill port, then the likely hook of you getting water into the breather line is much higher.

good luck!

Welcome Aboard....👍

In our experience...the slower you go the better it fills...too fast and it spills. 👍
Very small vent tube.🥴

Could you please describe in detail how you can see the water pouring “out from all over the top of the tank?”

Is your AS under renovation with flooring removed which lets you actually see the top of the water tank? Can you see where the water is leaving the fill tube?

More details would help the diagnosis. Has this happened before or is this a new-to-you trailer perhaps?

Thanks,

Peter

If I understand you correctly, the water backs out the fill tube? I have that problem with my 1988 Classic Limited. I have an endoscope so I put it down the fill tube and saw that the flexible hose inside had collapsed. My current solution is adapt a piece of narrow tubing to the white hose and to fill it VERY slowly. It takes about 45 minutes to fill the tank but eventually it fills.

I am not yet sure how to actually fix the problem.

We would fill normally with a hose just inside the fill area and never had a problem, now when we fill, you can see water pouring from all over, so something has come apart.

No renos. Normal fill with hose which was working previously. We just see water everywhere when trying to fill and nothing gets into the tank

Sounds like you need to dig into whatever cabinetry is hiding the fill tube so that you can actually see the tube top to bottom, and understand where it is broken or has become separated from the tank.

good luck!

Any plumber or electrician friends with a scope, per Doug? Rent one? [edit -- see PS2]

. . .

When filling with water, be careful not to jam the hose down the fill spout, but instead hold it free in the opening, and use a low volume flow. This way air can come back up the fill tube, without needing the air vent smaller tubing IMO.

If no water will go down the fill tube, maybe an animal crawled down there and got stuck?



Or the fill tube connection at the top of the tank failed, and shifted from road action? Somehow you need to get a look-see.

Good luck,

Peter

No need for a scope. You can see the end of the filler tube by removing the access door in the bottom of the FW tank cover.
I had the exact same problem with my Excella. I just finished repairing it.
The filler tube was decomposed and split right where it connected to the fitting at the tank.
I did not drop the tank cover, because the fresh water low point drains are routed through the cover with no access to the connection points. I was able to enlarge the existing access hole in the FW tank cover, enough to get my hand inside to unscrew the clamp and disconnect the 1-3/8" filler tube from the tank fitting.
Then I used a putty knife, pushing it in between the skin and the filler door, to cut the caulk and adhesive tape. It was difficult to pry loose, because it is caulked inside the wall, but I removed the filler door and tube. The vent tube was still connected, but I was able to disconnect it from the back of the door from the top side. Then I reinstalled the old door with a new filler tube
Sorry, I did not take photos.

I ordered a 3' x 1-3/8" rv tank filler hose. There was a small bit left when cut to length.

ps:
I started a thread, asking for advice. There is a photo here that helped me understand the water pipe low point drains. http://www.airforums.com/forums/f443...ml#post2229356

Great suggestions, Alan, however sgnen's 30' might have a different floor plan? Can you describe where your access door is, and how you accessed it?

I owned a 30' 1999 Excella before the two trailers I own now, so I am familiar with the layout of his. The bedroom, closet, hall and bath are the same as my 34'. The option of queen or twin does not change the wall layout. The extra 4' in the 34' vs the 30' is in the kitchen and living room. The more important difference is the positioning of 3 axles vs 2, which moves the water tank a little bit. Though, in both trailers the water fill tube is over the wheel well beneath the shower area.

The access opening cover is on the bottom of the tank cover, between the tank drain and the low point drains. It's roughly 5" x 8", from memory.
