We have a 2006 340DA and it now seems to be loosing potable water. Today I dried out the head and it seems that water is slowly (very slowly) leaking into the potty from under the toilet rim. I discovered something might be wrong when I was down in the bilge today and noticed the water pump running. When I shut off the power to the water system the pump stopped (to me that was a big first step) and helped me start to figure it out. I then started looking for leaks that might cause the pump to run. Thus the very slow leak into the head. It appears we lost about 20 gallons over the past week. I just don't know if this is the entire problem or not yet as the black water tank is not full. The mystery continues...
