I have a built in black tank flusher that has quit working . What I suspect is that the built in back flow preventer is stuck closed. However I'm not sure where to start looking for it. Any ideas or suggestions would be appreciated.
I have Dish TV at home and take it on the road. I was wondering if there was a satellite internet service that I can do the same? If there are more than one, which would be the best? I know that Dish offers it, but they said it would be a pain to take with me and set up with each move.
