how to empty black and gray tanks in a cougar 32rli travel trailer

I have a sliver valve to dump the black water but no valve to dump the grey water only a separate pipe next to it with no sliver valve. how do I dump the grey and do I need two sewer hoses.

Welcome to the forum

If you only have one 3" outlet and you see a 3" AND a 1 1/2" pipe connected to it then there will be a seperate handle to pull for the gray tank. Look up by the tires along the outside edge of the frame.

I have NEVER seen the gray tanks not have a separate valve. You may have to lay on your back and shimmy around, its there somewhere. DO you have a convenience center? maybe two pull handles there?

I have a 32RLI with the same setup. You'll need to get down low and look at the outside of your frame rail. The handle for the gray water dump valve is there UNLESS it's fallen off! If there's no handle, look to see if there's a 1/4 inch hole in the rail and a slit in the underbelly covering. It's never happened to me, but I understand that sometimes the actuator rod backs out of the threaded opening on the valve body.


Let us know what you find.

Interesting enough I just had something happen on this trip related to this conversation. At our first stop I dumped the black and then the gray. But the gray handle cam right out in my hand with the 8” of steel rod. This was the same handle that Is actually a replacement as the previous fell off. The foam was holding the handle in place...or it would have fallen out on the road. I had to cut away access tho the cell board and remove some roam insulation to find the other 1/2 of the rod to pull/open the gray tank valve. It’s now loctited together. Will deal with the rest when I return

While there are some Keystone models with 3 handles, the 32RLI's that I'm aware of have just one. Obviously that mean the 2 gray tanks are cross connected internally. Pull the one handle and both gray tanks empty simultaneously.

It is more effective to start your own thread as this one is a bit old. Next, put together a signature with your year, make and model of camper and the same for your tow vehicle. Thanks helps with context when you ask questions.

To your question, your dealer should have shown you how to use the dump valves when you went over things but if not, I doubt Keystone will be a lot of help. The manuals you received will be of no help as they are generic for almost all travel trailer models in the Cougar line. If I had to guess, you either have a "convenience center" behind the compartment door in front on the driver side with a dump valve labeled but if not, get under the camper behind the driver side rear wheel and you may see the valve there. That is a place Keystone likes to hide gray tank dump valves. Good luck and welcome.

Your 32RLI is very much like the 319RLS I had. There are three pull handles under the trailer. Two will be located near the main dump pipe; bathroom black and bathroom gray. One will be somewhere under the frame or maybe through the frame under the slide/behind (or right in front of) the wheels. Just helped a fellow with a new Cougar 364BHL (5th wheel) find his galley pull and he had to crawl under the trailer about 3' back inside the frame.
