Neptune (Cayman) Fresh Water Tank Leak

[major_west]

A few days after filling my fresh water tank, water started to pool on the floor of the wet bay.  I don't see any water leaking from the three connections to the tank (fill, drain, and gravity fill) that are visible in the wet bay.  The overflow connection is not visible, but I assume it is not leaking, since the tank only about 90% full.   So, maybe I have a hairline crack in the tank.  

Has anyone removed the fresh water tank from a Neptune or Cayman?  Any tips on how to remove it?  Mine sits below the black and grey tanks. 
Thanks

I get some dribble from the water inlet after I fill.  Maybe you didn't notice?

Is the puddle still growing?

Yes, sadly it's growing

Sorry I can not help with your question about removing the tank.  But I would think about draining the tank in 10% increments to see when the leaks stops.  This should tell you approximately at what height the leak is at.  And then go from there.

Great idea Bill R!  I'll definitely do that.  Thank you.

Did you figure this out? I have the exact same issue. Sometimes the drips move to the other side if I am not parked on level ground.

I've avoided over-filling the tank to the point that water is pushed through the over-flow pipe.  Since then, I've never found standing water in the wet bay.  

I can only guess the overflow pipe somehow allowed water to escape into the basement area.  Bill R's suggestion to fill the tank in increments until a leak appears is a good one.  

Hopefully, it's your overflow and not the tank leaking.
