Cougar Black Tank Rinse

Does anyone know exactly how the black tank rinse works on the 2018 Cougar 29 BHS? I can't remember how the dealer said it worked and where it's located.

Welcome to the forum

I can’t say where the hook up,is but if you have a convince center it’s probably located there.

How it works is you hook up your hose, NOT YOUR DRINKING WATER HOSE, to the port on the trailer, turn on the water and open the black tank drain valve. You should see a warning sticker very near the rinser port that says not to use it unless the valve is open. You can close the valve just DO NOT leave it unattended. The more liquid you can put in the tank, the better the flush and the more the solids will come out. You can repeat as many times as needed to see clean clear water. Most use a see through piece connected to the trailer and then the hose connected to it.

Don't know anything about your trailer but the black tank rinse is locate in the little cluster of water hookups on the outside of your trailer, and lableled, or in the convenience center of the hookups of your 5th wheel, again labeled.
