Fresh water tank leak

[The MaryAnn]

I have a small leak in my fresh water tank, the tank is enclosed so I can’t get to it, any recommendations how to seal it?

First check that it is the tank, not a fitting or hose that leaks.

First do what FF suggests. You may get lucky.

If my memory serves you have a Californian? 70s or 80s vintage? If I'm right about what boat you have you may have the layout where the tanks are between the stringers under the decks. If so there will be a small gap between the bottom of the tank and the bilge at the keel. You can use an inspection camera on an extension to look for the drip. Then you'll know where to cut to fix the leak.

Yes I have a 1979 Californian trawler, my boat captain said its enclosed so I cant check inside, I can move around below pretty well and see all the hoses. I'm going down tomorrow.

Looking inside was not my suggestion. Look under the tank in the gap between the tank bottom and keel.

Hopefully it will be something easier to fix like a hose leak.
