Hello Zia, I appreciate your feedback. I am new to the world of RV-ing and have quite an introduction since we purchase the 2 year old (2011) FC 23FB from a fellow eighty miles away. I should have turned it over to the dealer but then I would not have learned as much as I did by jumping in and attempting the repair ourselves. Glad your repair went well. Thanks again.

Good advice. Got up this morning to refill the tank and check the leak. One step forward and two backward. Now the drain fitting is leaking. The original leak is fixed with the Marine Tex. Wow! that is good stuff. I'll go through the same repair process to repair the drain fitting. After that and it still leaks, I'm taking it to the dealer.

Fresh water tank leak at the fitting

Just had my fresh water tank replaced at Airstream NW in Portland yesterday. Same symptom of a very slow drip as reported by others. 2010 FC 25FB I'm the original owner.
While the dealer said they do not see many tank replacements it does seem like a few folks have had compromised fresh water tank fittings? The tech said the other one looked weak as well. Other possible causes mentioned by the tech might be road vibration...
Pricey replacement.

They fail because the plumbing connection nipples were over torqued and bottomed out at the factory. The fitting eventually fails due to the stress and you have to replace the tank. This appears to be a reoccuring issue in certain years.

On mine, you could clearly see where the nipple was bottomed out so bad that it eventually cracked the boss and tore it from the tank. The tank replacement is a big job.

I replaced mine myself. Here's a thread which includes some photos of the failure. (lots of photos of the problem and the fix) Not only were the plumbing connections over-torqued so were the bolts on the mounting straps. Looks like the good country folks that build these things like to "ranch it down tight"!

I have a 2011 FB 23' with this same issue. I can see the location of the slow drip. I'm going to seal mine to eliminate (or at least reduce) the leak for an upcoming trip. If it still leaks after that, I'll decide whether to replace the tank.

Thanks to all the comments and info!! Very helpful!

The tank is encased in Styrofoam and will not hold water. Once thing have settled down slowly fill the tank through the line that feeds the pump. Disconnect at the pump and make a connection to a garden hose. By back weeding the tank this way you are eliminating the fill tube, which may be loose at the tank connection. If it leaks this way you know it is the tank.

Once you determine if it is the tank and not the fill tube you can decide what to do.

If it is the tank and you have the ability to drop the belly pan do so and look around. An ABS tank can be fiber-glassed. Not sure about a poly tank.

$700.00 without them even knowing waht the problem is sounds like a Profit Center to me
I believe I overpressurized my tank filling it with water and popped a seam. I had a garden hose tightly fitted into the fresh water inlet and pulled it off in a big hurry when I saw the inside floor bulging upward. I got a 6 foot geyser of water out of the inlet.

In any event it leaks now and appears to be be getting worse. Leaks from the belly pan port and starboard for several days. I will try the fill through the water pump hose trick and see what happens.

If the leak turns out to be a fitting or line and not the tank is there a fix short of dropping the tank?

How big a job is dropping a tank on my 71?
