Shower sump pump stuck continuously running in my 2008 36/Super Sport. I want to check/clean the float switch, however the location of sound brings be directly under the Fwd stateroom bed which has the A/C unit in a molded fiberglass box Drain lines from the shower and Head sink run to this location. Problem is, the A/C & Bow-Thruster control unit are in the molded box, I see no easy way to access where the pump sound is coming from. There are even two smaller access holes under the bed support to left & right (of the larger A/C box) however, I see no sump holding tank only grey water & power lines. I am sure it is directly under the Bed & A/C box, but I can't get to it? Any guidance would be appreciated!
