Mid-ship Bilge - Where does that water come from?

gslpro

On my 2004 290Fv, I had water in my mid-ship bilge for the first time that I could not account for it.  After a big rain, I would have some, and my thinking was that it was from whatever water came in to the cockpit area, and ran down.  Been dry as a bone for a few days, and I know I hit the bilge pump switch when I arrived at the boat a few days ago.  I would guess between a gallon and two pumped out this morning.  So, where did it come from in the last couple of days??  I have a drain line for the A/C, though now that I think about it, I should probably check that with all the heat we have been having.  I have a sump pump for the head shower/sink, and another for the galley.  Cockpit sink runs right into the tank.  Rear bilge has the 1/4 gallon of stale water that always seems to be in there.  I am confused. But, besides that A/C line that I am now thinking about, where would it come from.  If the drainline clogs, would it flow to the mid-bilge?  The A/C is at the very front of the bow.  Thanks for any ideas.

Mine filled up from the thru hull where the macerator pump would discharge out.

Thanks Handyman.  No Y-Valve.  Toilet goes right to the holding tank.  I wish the were real schematics like you can get for other vehicles.

All heads go to the holding tank. The Y-valve goes from the holding tank to the overboard macerator and the shore waste pump out.

The macerator would discharge out the bottom of the hull.

Glspro not sure if you fixed mid water issue yet but had the same problem was water tabs in the head leaking
