Updated - Please read 1st post: Some basic sewer questions

Update:

THESE QUESTIONS ARE NOT ABOUT AN RV.

Well, it is not an rv YET, anyway ;). It is a cargo van I am building into an rv. Right now it has no tanks, and no plumbing at all.

I have experience putting in s&b plumbing, but am not familiar with rv systems and don't have an rv to look at.

Responses that tell me to 'look at my tanks' or 'post pictures' are well intentioned but not relevant to the topic.

If anybody reading this can post a picture of the sewer outlet, with hose NOT attached, on your own rv, that would be so helpful!

--

So it looks like I may be staying the winter in a park without a public bathhouse. I'll need to put in a standard sewer hookup. But iI have never seen one up close!

Google and youtube were not much help. Would one of you kindly walk me through the basics?


= Does the bayonet end of the hose connect to the rv, and is the other end threaded to screw onto the sewer outlet in the same threads as its lid?

= Do all rigs have the bayonet fitting, or does that vary?

= I am thinking I will use the hookup for grey water only, and remove the hose to dump my portapotty, that way I will not have to have tanks. So I would just plumb in sink and shower drain lines, shutoff valve, and whatever the sewer hose hooks onto.
Does this sound OK?

= If the hose does screw onto the ground hookup, is there a quick release version that could be less hassle for ports potty access?

Thanks much for any advice!

    That's Ed Norton (Art Carney) from "The honeymooners" 50s sitcom. He worked in the sewers.

    Thanks, Don and Lorri. The bit about multiple threads was helpful :).

    What I am uncertain about is the rv end, the part that comes pre-installed at the rv factory. My van does not have that, and I am not 100% sure I know what to install.
  • You will need a standard RV 4 inch sewer hose in the correct length to go from your RVs dump port to the parks sewer connecrion. You will need some way to securely connect, usually an elbow with various thread sizes that screws into the sewer inlet. You will need a bayonet fitting to connect the hose to your dump outlet. Connect things together and your good to go. Leave the black tank valve closed until time to dump, usually at least 3/4 full. You can leave the gray tank valves open. I generally close my gray valves the day before I plan to dump my black tank. I use the stored gray water to flush the hose and lines after dumping the black tank.
