The water is dripping from the upper edge of the grey water tank where it connects to the floor. Location: front side near the drain valves behind the driver's side wheel. When I disconnect from city water the drip slows, but does not stop completely. We have almost no water in the grey tank since we just hooked up. There are no signs of any leaks inside the trailer. The sensor for the holding tanks indicates that it is empty, but the sensor shows the fresh water tank is full when it has not been filled at all. The drip is not present when we are not hooked up to city water. Help? Any ideas? Thanks in advance.
