Our shower room had a plugged drain. I have no idea where the comforter bilge is or where the water goes once it leaves the shower room. When we throw the breaker switch on the control panel and then push in the power button in the shower room no draining would take place. I used the dinghy foot pump inserted into the drain hole in the shower room without results. I disconnected the hose from the electric bilge pump at the stern of the boat and applied the dinghy foot pump; no results. I used a wire snake inserted into the drain of the shower room, got resistence, pushed some more and then the water suddenly drained into the regular bilge area. What's happening and how do I correct things??? Also, what is the design of the drain for the comforter in the shower room and in the head room??? We have a large black lab that sheds an incredible lot of hair and adds a need for regular filter maintenance. Thanks in advance! Ron
