I tried using my black tank flush feature today and it didn't work. (you can find the whole sordid story in another thread) First thing I did was flood the bathroom as the QC people at FR must have been asleep. The hose wasn't tight on the backflow preventer valve. I tightened the valve, turned on the water and it still wouldn't work.
Could I have damaged the valve when I blew the air through it? I only put about 35psi into it. A bunch of you are saying I really didn't screw up and that you blow out your black water flush system.
And, thank you for not making me feel like a complete idiot! Apparently I'm in very good company here.
