Our 2003 U-320 water tank seems to be running into the red very quickly lately. We totally fill the tank until the auto shutoff (we think) stops the flow but we run low on fresh water when gray is 1/4 full and black has only a couple lines showing. No leaks that we can find. So we're thinking the auto shutoff valve may be acting up. Can't find any info on valve but...
