I used to have an Ericson 1987 38-200. So I feel a little dumb but can't seem to find access to the shower sump of my friends newly acquired 1992 Ericson 34. The manual says forward the head but there is no pump located in the pan of the shower. No hatch I can find. The drain hole seems like a dead end. The sole seems like not original, but a faux material on top. Was the hatch for sump pump covered over? The pan fills but doesn't drain. Maybe the sump itself is shot, but can't find where located?
