Here is an update to my "Dumping" Saga. We talked with a Nothwood Rep yesterday and he tells us that our Dumping Station is fine. He told us that we need to double, even triple the amount of holding tank cleaner we use, so that the valves stay lubed. He also suggested that we use more water. The first part I am willing to try and will let you know if that works. I do have an issue with using more water, because we dry camp 95% of the time. I have everyone trained to use water sparingly, so imagine how confused they will be when I tell them to just use the water. LOL The Northwood Rep also recommended that we use a product called, "Odorlos" for all the tanks. I will get some and let you know if that does the trick.. Again, thanks for all the advice.
