Hello All. Drained all tanks before leaving campground on Sept 23 and all tanks drained normal. At the end of the week at the next campground, went to drain my tanks again. Gray #2 was already empty. This after washing dishes and other water uses in kitchen. Black water tank seemed to fill up premature based on other trips. Gray #1 drained normal. There was no evidence of water leakage under RV so where did the water go from Gray #2? Kept all valves closed during that last week of camping and only opened at end of week to do normal draining. Is there some way that the water from Gray #2 infiltrated either the Black tank or Gray #1? Again, all valves were closed so unless there is a malfunctioning connection at Gray 2 that did not completely close the valve, can't understand the disappearance of the water. Going to test this week by running water into kitchen sink with Gray 2 valve open to see if water comes out. Then will close the valve while water still in sink to see if it holds the water back as normal. I do have the add-on valve at discharge point that protects me from surprises. Interested if anyone has experienced this issue or has suggestions.
