Wet spot in cabin floor!

[Johnc3211]

I've got a 93 250 EC with a small wet spot near the middle of the cabin floor. I have had standing water in that area twice before. In 2021 while on the trailer in driveway I was working on outdrive and had the trailer jack low to raise outdrive up. It rained and my forward bilge pump switch failed. Had about 3 inches of water in floor. My boat is similar to a Sundancer except the cockpit floor is lower and no berth under helm area and only 2 steps down to cabin floor. One step is in cockpit with drain to forward bilge under that step. The second time in 2022 we were sleeping in cabin and it rained hard overnight and left an inch of water in floor. That time the pump failed. Both times the bilge overflowed onto floor. Just today we find a small wet spot in carpet. I can see into bilge area and there is not enough water to trip the pump. The float switch is below the cabin floor level. Looking with a mirror I can see the bulkhead between the floor and the bilge area is in good shape. We don't use the shower or onboard water at all. Could the area between bulkheads in the floor area be full of water from those previous overflows that it is seeping up through the floor? I ordered a 4 inch round hatch so I can drill a hole and see what is going on. Anybody have any thoughts? Thanks
