Black Water tank flush system clogged

We have a 2000 CC Intrigue. Both holding tank have a hose fitting to hook up a garden hose to flush the tank.
The Gray water tank seems to work just fine, dump the tank, hook up the flushing hose and you can see a large volume of water in the discharge line.
The black water flush fitting seems to be "clogged", hook up the flushing hose (dedicated to black water only) and the out put is just a dribble. Close the main dump valve and let the flush hose run for 5 minutes and the discharge volume is better but not like the gray water.
Does anyone know how the plumbing is set up on this system? I'm afraid to start with compressed air or high water pressure to try to "clean the system out" since I don't know how it is plumbed.
I'd really like the system to work as designed so any help would be appreciated. Thanks.

Ours is a 04 Allure so could be different. Chech your manuals to see where the black tank nozzle enters the tank. Three screws remove it. Pull it out enough to over drill the nozzle holes to a larger diameter. From memory, mine wen about 1/8th oversize from stock.

Did this once, and had worked well. Yahoo user group for CC has a few pictures - I think from Dallas.

Best of luck,

There is a backflow preventer valve in the system and it can go bad. The diaphram comes loose and will not allow water to flow through it.

On my '02, the hose connection is in the plumbing bay. There is a plate on the opposite side of the coach in the short bay in front of the wheel. Removing that plate exposes the in tank flusher. The hose runs over the top of the tank.

Backflow valve on the fresh water did the same thing on our fiver 2yrs ago, it was a 3yr old valve but still died early.
