Winterizing the Black Flush?
Hope everyone had a great season and I'm sad that I'm writing about winterizing :-(
I have a new unit this year (2009 Rockwood Ultralite 2701ss). It came equipped with a black flush for cleaning the black tank. (awesome feature, used it 3 times this year and I couldn't believe what it got out!)
Anyhow, I'm wondering if there is anything special that needs to be done to winterize the black flush? It has an inlet that looks just like the city water inlet from the outside, but I did open the screen and noticed there was not a back flow preventer, so it almost looked more like a fill valve. Since it's flat against the trailer, it's tough to pour anything in it, I didn't have a funnel with small & long enough tip to try and see if you can pour anything down there.
But I'm wondering, does this need to be winterized in some fashion? Or I'm wondering if the water just drops right into the black tank and therefore there is not water left in the hose that would need to be winterized?
Any advice or tips would be greatly appreciated! Everything else is done at this point!
