We continue to find out things out about our "Black Beauty". We are going thru a wicked cold snap down here on coastal Alabama. To prevent our water hose from freezing we set all three of our sinks to a slow stream and leave the grey water valve open.
About 2:00 am I made a bathroom trip and found the bathroom sink just about to go over the top. Oh NO, I thought, the drain line froze. However, the kitchen and the sink in the bedroom were fine.
THE ROOT OF THE PROBLEM: The sink in the bathroom drains right into the black tank. OMG

I wonder how much they saved on that short cut? good grief!!!!!!!
