Cougar 25res black tank flush not labeled

[Shinchman]

I have a 2018 Cougar 25res. I went to empty and flush the blank tank today. I was able to empty the black tank but could not flush it because the black tank flush connector is not labeled. In fact there are 2 unlabeled hose connectors in the maintenance station. Can someone please tell me which of these 2 hose connectors is the black tank flush and what the other unlabeled one is for?

I don't own your trailer, so just my opinion.

One will be the tank flush. When you run it, you should be able to hear it filling the tank.

The other is probably your fresh water/city water connection. When you hook it up, with the water pump off, you'd get water out of the faucets.

That's how to tell them apart if someone with your unit does not chime in soon. Good luck.

If they are color coded, as a general rule white is used for fresh water and winterizing, and black is used for waste water rinsing.

Thx but all 3 are white and only one is labeled “city water” connection.

On our trailer, the black tank flush has a sanitation warning label beneath it. The city water connection is labeled as such. The remaining hose connection is for the winterizing suction hose.
