Default Sea Ray Sundancer 250 DA bilge queation


3. One of the inlet hoses to the sump has come off the sump or is
otherwise leaking its contents into the compartment before it gets to the
sump.


Could also be the outlet hose from the sump has gone defective or come
loose, resulting in the sump pumping the water from the sump into the bilge
compartment. This would be obvious when testing the sump and observing its
behavior. If the pump activates, make sure the pumped water is making it
out the through-hull fitting overboard.

Also, when testing the sump, make sure your electrical switches, (battery
switches, etc.) are in the same position as when you are off the boat. The
sump should be wired directly to the batteries, just as with the aft bilge
pumps, making the switch positions irrelevant, but you never know for sure
unless you test. In other words, you want to make sure the sump has power
routed to it when the boat is in storage or idle condition. Are the
batteries in good condition?

Does your boat have air conditioning? If so, do you leave it on while away
(assuming your boat is wet slipped)? I have seen a situation on a friend's
larger Sundancer where the drain on the pan of the AC unit was plugged or
partially plugged causing the pan to overflow and send water where it
shouldn't go. I know you think your problem is rain water, and it most
likely is, but understand that if your AC is left running during highly
humid conditions (like a warm summer rainstorm), a large amount of moisture
will be removed from the ambient air resulting in a significant amount of
water in the AC drain pan. A very remote possibility, but something to
think about if you are having difficulty finding the source from more likely
places.
