LandB Report post Posted June 21, 2014 I have a 2007 Monaco Camelot and I can no longer add any water using the black water tank flush connection. It has worked in the past but no longer. I believe there is a check valve in the line somewhere, but not sure where. I have removed the hose connection/plate and it is not on the backside. I have been told it may be in the cabinet under the bathroom sink, but doesn't appear to be there either. I called Allied Recreation Group (Monaco), but they have not called back so far. Any ideas would be appreciated. Larry Share this post Link to post Share on other sites
F355197 Report post Posted June 21, 2014 I had a similar problem with our Exec. I removed the spray head and cleaned the holes with a thin wire. With spray head removed I verified flow before re-installing. It has worked fine since. Share this post Link to post Share on other sites
LandB Report post Posted June 21, 2014 How did you get access to the spray head? I can't seem to find any way to gain access to any of the area above the tanks. Larry Share this post Link to post Share on other sites
F355197 Report post Posted June 21, 2014 On ours the spray head is at the opposite end of the tank from the dump valves. The panel over this end of the waste tanks has two latches underneath. I don't know that yours is the same but it should be similar. Share this post Link to post Share on other sites
dives Report post Posted July 30, 2017 You can probably find the black tank flush check-valve under the bathroom sink along with a pressure valve. Share this post Link to post Share on other sites
hermanmullins Report post Posted July 31, 2017 Just to point out this post is three years old and the OP's last post was June 21, 2014. Hope he got his black tank flushed. 😝😷 Herman Share this post Link to post Share on other sites
