Lincoln Winterizing - what are these for?
I've had this for nearly five years (bought it used), but first time I've had to winterize. Was living in it full time, so always had heat on. Turning off the water to the hot water was pretty easy, it's drained. I've blown out the lines once, but I still have to crawl into the basement and take the water filter off. And whoever decided to put that there should be flogged, tarred, feathered, and then set on fire. But back to the topic at hand.
Does anyone know what these two levers are for? With the label above, I'm guessing it has something to do with flushing! But are they for winterizing, or flushing the grey tanks as well as the black, or ... And then the other label says "low points", but it is below the black tank flush hookup. I've no clue.
