What you are looking at above is the correct way to hook up a sewer hose in a 2001 Newmar Dutch Star motor home. The reason you are seeing it is because it’s not quite as obvious as you might think it is.
The purplish tint is applied to stuff that’s not really important in this post. What’s important is that are usually two valves in a motor home waste system and they empty into a sewer hose that normally goes through the floor and then into a sewer cap.
In the picture to the right, you can see the different valves and labels. The “sewage water holding tank” (commonly called black water) is the valve for dumping everything from the toilet. The gray water valve on the right dumps the waste water from all the sinks and the shower.
When we got the Star and I started checking everything out, I couldn’t get the clear elbow to attach to outlet correctly. I also couldn’t get a sewer hose to attach and then bend backwards to go through the big hole in the floor.
In this picture, you can see the clear elbow attached, but it sticks out too far. Normally a sewer hose goes on the bottom of that elbow and then goes through the hole in the floor. The elbow sticks out too far and there isn’t enough room for the hose to come up through the hole.
I figured that someone had damaged the original pipe system and then replaced it all with the stuff we have now. I was planning on ripping it all out and rebuilding it. But first, I wanted to see what the original system was supposed to look like.
Luckily, while we were at Sun N Fun RV Resort in Sarasota, we spotted another Dutch Star that was very similar to ours. We stopped as the owners were coming out so I asked if I could look at the guy’s sewer system.
As we were walking around to the sewer bay, I started to explain my issue. The gentleman mentioned that his outlet pipe swiveled down to line up with the hole. When we got to the bay and started looking, I instantly realized it was exactly the same system as ours. Hmm…
We probably would not have figured this out. I might have gotten lucky and realized it moved when I went to rip it out, but that’s not really very likely. Just talking to another owner and doing a bit of exploration saved us a lot of time, effort, inconvenience and probably a fair chunk of money too.
In short, if something doesn’t seem right on an RV, ask others who would have had to deal with the same issue. If you can find someone with the same unit, that’s even better!
