I have a 2003 Carver 366 and I have a fresh water leak in the forward bilge.
Turn shore water off and fresh water pump off leak goes away.
The water is coming from under the black water tank. In the 366 there are two hatches to the front bilge, one in the galley and one in the forward berth. I used a shop vac and paper towel to dry everything up. Once dry I turned the shore water back on and a little water started showing from the front of the black tank but not the rear.
All water lines are pex and I have checked all the ones I can access. I have check the fresh water pump. I even checked the hot water tank and through hulls everything is dry. I do believe on the 366 there are three separate bilges that are not connected, front mid and rear. That is also what it looks like. Any help would be greatly appreciated.
