When I bought my M-382 (1981) last summer, it was in pretty neglected shape. After 8 mos. of work, I'm down to some smaller projects now. I need advice on where and how the shower sump pump suction is hooked up. Right now the suction piping is hanging loose ( not connected to anything except the pump suction). I have felt around under the cabin sole in front of the head sink for some type of pipe to hook up to and can feel small pipe running from the shower drain to the sole drain at the sink. Can't feel anything to hook the suction line to. I thought that the shower may drain to the sump in the bilge just ahead of the mast step, but there is a passage for water between the bilge sump and the mast step. Any info on how to hook up the suction line would be appreciated.
