Question about tanks and "dummy lights"
Last night, we "dumped" the grey and black water tanks from what was in there when I bought the coach.
Couple of questions:
1. Using the "test" button above the stove, it is labeled Holding tank 1 and holding tank 2, question is which one is the black water and which one is the grey water?
2. When you connect a hose to the inlet down in front of the grey water valve, and put water into the tank(s) which tank does that go into? My guess is that it goes into the black tank so that you can flush any remaining solids?
My test indicator says that holding tank 1 is 2/3 full and holding tank 2 is 1/3 full. I was connected to the sewer for almost 10 hours last night at the campground that we stayed at. I left the grey valve open and the black one closed, (heard that on youtube) to fully drain the tanks, but tank 1 is still almost full. After opening the black valve and waiting for the sound to stop, I then re-opened the grey valve to flush. Waited for the sounds to stop then closed that valve, however the lights inside still don't show empty...
Does not really matter what the "dummy lights" say, I just want to prevent a back-up, so I am going to assume (for the sake of this conversation) that the lights are accurate.
Going to connect to the sewer tomorrow after I fix a small leak in the sewer hose & change to a clear end so I can see when the fresh water is flushing thru the hose.
Thanks for any assistance.
