Black Tank Flush Valve

Can anyone tell me where the black tank flush valve is located on a 3650RK...It is probably an 2005.. or newer.. not sure about that.. Someone in the campground cannot get the black tank to flush. He cannot find the valve.. Just trying to help someone out..
Thanks..

Hi

Ours isn’t a “valve” it’s just a water hose connection in the convenience compartment with the rest of the waster control equipment and valves.

On my 2005 2980RL ... as with most other models of the time, it was a female hose connection on the street side of the fiver just to the rear of the cargo bay door. Screw a male hose end onto the fitting and turn on the water. If you are talking about the backflo preventer valve ... someone else will have to help as they were usually behind the bathroom sink or in the wall behind the shower.

ifw mine is behind the shower and can be reached from the closet at the entrance. mine will not spray sometimes if the water pressure is low. I would like to rework mine at some point also. I have had the belly down to repair the gray tank and the pipe just comes from the inlet side and down and under the tank and in the end at the bottom on the entrance side. my 06 has no conv center just a inlet on the side above the city water. if I can be of any help just ask.

The valve will be located near or directly over the black tank, on my Cougar it's under the bathroom sink. As in any vent it's got to be above and pretty close to the tank it's venting.
