When we took our Aliner Scout out for our first camping trip a few weeks ago, we couldn’t connect the gray water drain to the campground sewer system. Today, we’ll show you how now that we know.

This is the perfect example of the model for our newsletter, podcast and YouTube show. We make mistakes, learn from them and then share what we learn so you don’t have to make the same errors.

Camping in Florida, where there is plenty of water, is different than camping in Utah’s deserts or other places where it may be okay to drain your gray water on the ground. We really want to connect to the sewer hookup in the campground to avoid creating a puddle of toothpaste and dish soap near our rig.

The Aliner Scout we tow with our Chevy Bolt is super lightweight. It not only has no bathroom and so no black water system or tank, but it also has no tanks at all. We can connect water, but there is no holding tank for clean or gray water. This is great because it keeps the trailer light and towable.

For us, without tanks, we need to have the gray water connected to the sewer so we can have water in the trailer when we camp.

After we discovered our error, we asked around and quickly learned that this is an unusual configuration. Most RVs have small bathrooms and holding tanks of various sizes. It was hard to find anyone who could guide us. That also helped us conclude this was an important subject for us to cover.

There are three parts required to drain the gray water from the Aliner Scout directly into the campground RV sewer. A standard hose carries the water using two different adapters, one on each end.

At the trailer, the drain is 1.5 inches. We couldn’t find any hoses that size. We found the Valterra T01-0091VP Swivel Drain Connector, which allowed us to connect the hose to the trailer.

We purchased the Valterra Flushing Hose for RVs. Virtually any hose would work. The only reason we chose to buy this one is that it is gray. By getting a gray hose, we won’t confuse it with the blue one we use for clean water. The last thing we want to do is use this gray water hose to connect our clean water supply in the future.

The final piece was the most difficult to find. When you don’t know the name of the thing you want, it is hard to search successfully. With some help in an RV forum, we got some clues that helped us find this Camco Easy Slip Gray Water Drain Adapter. It connects to the standard RV sewer connector you probably already have.

Connecting those three parts is pretty simple. If you have questions, be sure to watch the video above, which should answer them. Feel free to post suggestions, comments and questions below or, if you’re reading this in your email, just reply.
