2022 Minnie 2529RG - Fresh water tank filling problem

[epnh]

On my new (to me) 2022 Minnie 2529RG, I find that I can only fill up the specified 60 gallon fresh water tank to about 21 gallons before the water starts overflowing out the fill port. Then I turn on faucets and run the water down to where the water pump starts sucking qir and no longer delivers a useable water flow. At that point, using the master fresh water tank drain (on the frame just forward of the bedroom stairs) I can drain another 9 gallons out of the fresh water tank. So, I only end up with about 12 gallons usable out of a 60-gallon tank.

Anybody else have that issue?

I thought it might be the gravity-feed vent line is plugged but that wouldn't account for being able to consistently put 21 gallons in the tank before it overflows.

Hi Eric,
Could it be that the tank is "U" shaped, and one of the two vents was never hooked-up? Hopefully, somebody else here has seen this problem and can give us an answer.

Good morning, Eagle5.

Anything is possible but that seems relatively unlikely. I have some official Winnebago drawings of this trailer including location and size of the fresh water tank which they illustrate as a box 64 inches long by 34 inches wide by 7 inches tall which calculates out to just north of 66 gallons. I'm hoping to find out today what the real problem is.

Fresh Water Tank not filling 2024 Minnie 2529RG

First time filling fresh water tank, 60 gallons, it only took about 10 gallons and started coming out the inlet on the outside. Also, the vent pipe filled with water. What could be wrong? The trailer is a 2024 Minnie 2529RG.

I had a similar problem and found that the plastic fill line on the inside of the trailer from the fill point was not well secured or fastened down in a downward slope. I would start filling and it would flush back at me within about 10-12 gallons of filling. Once I straighten the line and better secured it, I don’t have that problem. Of course I had to cut into the underbelly wrap to see the problem and correct it. I then used black tape to seal where I cut the underbelly wrap. (I attached a pic of what I taped with). Hope this helps.

Thanks to everyone for your help. The problem was the fill pipe itself is misrouted. After that was fixed water flows as it should and fills the fresh tank.

How this wasn't a problem for the previous owner is a mystery. Maybe they never used the fresh tank and only used city water. Or maybe they didn't care about being able to fill past 12 gallons usable.

One of the great mysteries of life, I guess.
