My Sabre 36QBOK has a total of 5 waste water tanks and two sewer connections on the side of the camper. Cue scenes from RV… only now times TWO! Once I got down to business, it hasn’t been so bad. Here’s my setup.
From each of the sewer connections on the camper, I directly connect to a clear plastic elbow (kind of gross yes, but my dumping procedure has me flush with water until it’s just clear water running out and you can’t see that without a clear piece):
From the clear connection, I have hooked up my hoses. I carry two 20′ lengths and two 10′ lengths of hose. I actually wouldn’t mind carrying a pair of 5′ lengths to give me a little more flexibility:
I bring the hoses together using a wye (fancy talk for a “Y”). It has swiveling connectors which supposedly help (shrugs shoulders):
And that finally goes to my 90° adapter that connects to the site’s sewer connection. The one I have is nice because it twists and locks (if the site connection is threaded, of course). I bought mine as part of a “sewer kit” like this one:
About the only other thing that I’ve done was that I had to buy a sewer donut for some setups where the sewer connection isn’t threaded. You mash it in and then mash your hose/adapter through it. I’ve had nothing but bad luck with them, but they’re required some places.
