The shower in my 322 drains way-y-y too slowly, and I'd like to troubleshoot the system, but with a molded-in head floor, it's kind of hard to trace the plumbing run from the drain. Where would I begin to look to find the pump? Under the sink? In a remote location like a lazarette? Or is it not that straightforward, maybe individualized for each boat? (FWIW, the shower sump is controlled by a dedicated breaker on the 12v panel, and then a pullout knob on the head vanity, just aft of the sink. See photo.) Thanks in advance for any help.
