I do not have a leak anywhere in my system. No cracks in my fresh,grey, or black water tanks. After traveling several hundred miles in the rain when I stopped overnight I noticed my coraplast sagging. I drilled a small hole in the coraplast in 2 places where it sagged the most and drained. I have been stationary for a month staying in the coach and no more has drained out. Could it be possible the water accumulation was from driving in the rain?
