Winterizing hint - don't forget
Don't forget to push some antifreeze thru the black tank flush water inlet. I had to replace the check valve (located behind the wall paneling) because the first use in the spring it leaked and had water all over the floor.
I got by without winterizing the black flush line for several years until it froze and split the backflow valve.
And after replacing the backflow check valve once, I've made sure the black water tank flush line/valve gets winterized every fall.
