Went out this past weekend for our 4th trip in a 2011 Cyclone 3950 and finally got around to giving that black tank flush system a go. I drained all my tanks like normal and then hooked up the water supply line to the flush fitting. I verified the tank drain valve was open, and then cracked open the supply water. I have a clear elbow at the drain pipe so I can keep an eye on what's coming out, but nothing appeared to be coming out. A quick glance showed water coming out of where all hookups are, and water in my storage compartment.
I pulled off the access panel inside the storage bay that would allow me to view the backside of all the hookups, hooked up water again, and got water spraying out the front of the sani flush connection as well as the back of the connection (usually not visible because it's behind the access panel).
Next thing I did was disconnect the campers water line from the back of the sani flush connection, which is pretty much just a check valve (functioning as best I can tell) and try to blow through the line. It was fairly hard to blow through and I could tell that there was water in the line and the far end felt like it was submerged. That didn't make sense to me since the black tank had been emptied, and I would have thought the nozzle end of the flush system would be positioned quite high in the tank. I called it quits at that point and headed for home.
Once back home I tried blowing through that line again and now it's plugged solid. I can't blow a bit of air through it. None.I'm fairly certain the reason I was spraying water everywhere was because this line was/is somehow restricted and that water pressure had to go somewhere. I opened up every spigot in the place and got nowhere as far as being able to blow air through the line.
I called Heartland customer service and whoever I spoke to seemed to think I needed a new check valve but unless there is more than one check valve I'm not convinced. He didn't seem to be grasping that I could remove the check valve from the equation and simply could not force any air through the line.
Hopefully I've been clear enough in my description. Anybody that could shed any insight on the system and how I might trouble-shoot it myself, please feel free to step in. I called my dealer who was supposed to have one of their techs give me a call, but par for the course I received no call back. Since getting anything done there seems to require the standard Month of Sundays I'd just as soon avoid them if possible.
