Lincoln Winterizing - what are these for?

[Old Bear]

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.

They are for the low point drains. You should open them to drain out the water that lies low, and blow them out or close them and make sure some anti freeze fills them also.

Where do they drain out to? I haven't noticed any tubes poking out the bottom, but I'm sure I could have missed something!

Mine run out the bottom. You may have to search for them, but they are there.

If they are like mine, they will be directly below the valves. Sticking out the bottom.

Mine drop out through the fabric on the underside, just below the valves. Knowing the quality & care that trailers are built with, it's possible they didn't extend them all the way down, or maybe even forgot the drop tubes all together.
