I'd love to know where you located the pump and where it discharges.

I also threw an absorbent towel (like a sham-wow) in the bilge which catches most of the drips before they can run under the tank. When i suspect water in the bilge I flip the switch and let the jabsco pump out the water. The clear hose makes it easy to see when all of the water is expelled. Highly recommended.
