fresh water tank leaking

[tc'sbackporch]

we have a 4207 and the fresh water tank is a bladder under the floor beside the dinette table and the pantry. has anyone took one out and repaired it.

I am sure someone with a 4207 will chime in, but I do not believe that is the original tank. For 87, I'm pretty sure it would have been a plastic tank.

Our 89 4207 had a plastic tank.

friend of mine had one and it had a bladder tank also but it was under the masterbed

Just curious, never seen one.......what is it made out of ? if you empty it and suck the air out would that flatten it enough to remove thru the hatch.....maybe then a simple patch.....

I have a 1990 4207 and my fresh water tank is aluminum and I think it is leaking can’t see where but it’s empty a couple days after filling it following

Ah there is the answer, those aluminum tanks should never have been used for water or holding tanks for that matter as they corrode/oxidize and will eventually leak, there is no repairing those as they are pitted everywhere upon further inspection. The previous owner probably replaced the tank with a bladder.
