@Homebodyatheart works as advertised. Garage never gets below 40*. IMHO it would ok to dewinterize now. Even if it were to drop below freezing at night it wouldn’t be long enough to do any damage.
Dale, there's a bit of a contradiction in your illustrations vs parts list...
The slip tee you used in your installation photos looks to be part of a 'slip tee / waste outlet' fitting. ie:
Wouldn't that be easier than the triple-slip tee?
Also, a question. The el between the sink outlet and the Hepvo is a slip fitting, isn't it? How do you seal the threaded sink outlet to the slip-fitting el? edit: I now see, it's not a slip-joint. I found the video here.

Very true I can’t get anything by some of you. In my case I did use a T like you picture d. Instead of the slip fit T in the parts list. I all ready had one and it saved me a trip to HDI placed it in the inverted position. By doing that it was necessary remove the baffle inside it with a small grinder. The standard slip T should be easier for the average person. Either way will get the job done.
@Photomom, I wondered the same thing, but got to thinking (uh oh). It's a possiblility that that vent pipe is the main 'stack' vent for the gray water.
IOW, the shower drain might also depend on that vent pipe. (I haven't looked in that wall behind the toilet in a while).
But, on second thought (uh oh!), combining a drain and a vent like that might be unacceptable...

Sigh... Like the discharge mod in that a shopping trip south may be in order. The challenge of living in the land of snow.... Good to know that direct purchase is an option because Amazon.ca is not.

If my plumbing schematic is to be believed, the gray tank (and by association the shower) do indeed vent up past the sink drain.
So, while the Hepco valve itself may not require a vent, you should still reconnect as Dalehelman has.
Draining into a pipe that serves as vent for a fixture lower down is called "wet venting." Residential plumbing codes do prohibit it in certain situations, but I don't recall the specifics. I think it has to do with toilets on upper floors, so unless you've installed an extra can on the roof of your T@B, you should be good to go. ;-)

@ ScottG thanks for answering the question. You did it better than I could have. I tried without. The water entering the gray tank forced the air up through the shower drain. Correct that vent is needed for the shower.
The Dutchman T@Bs have a strainer/sink adapter that includes a check valve style waterless trap. In the picture it is the round bottom white unit on the bottom of the sink. The entire drain plumbing is the corrugated grey hose leading to a 3/4 inch threaded hose connection beneath the trailer.
@Sandiegogal Our next mod......this will eliminate the weird smell in the trailer. HepvO® valve.... who knew this even existed? The HepvO® valve means enhanced plumbing design and system efficiency, without compromising performance or risking the escape of foul air into the living space from the drain or sewer.

I assume you have know holding tank. If that is true then no “P” is needed

About a year ago, I bought all the parts I'd need to reroute the drain and trap under the kitchen sink (ours drains toward the front of the cabinet).
Haven't got a round tewitt though, of course, and now I have to find a use for all those parts, cuz this is a much better solution!
Thanks Dale. Love it!
