Which Vent is Which

[Scheinin]

I spoke with Gary Bunzer at both the FROG rally and yesterday at the Hershey PA rally, and he convinced me to get the 360 vent. The trouble is, looking on the roof of my 2016 36CKTS, I can't tell what vent is what.

I have 2 of these vents:

When I take the cover off, this is what I see:


I also have this 3rd vent, could not get cover off:


Any Cedar Creek owner know which is which?

The first 2 vents are attic vents, which help keep moisture out of the attic. The third pic is the bathroom vent. That is where the 360 will go.

Thank you.

I wouldn’t call the 3rd vent a “bathroom vent”. It’s a tank vent cover. Could be for a grey tank or a black tank. Our Rockwood has two of those - one for each tank. Uncover the caulking on the top and you should see a screw that holds the cap on but if you’re installing the 360 Siphon, you just need to uncover the screws on the bottom flange that secure it to the roof. Use a hair dryer to soften the caulk and a plastic putty knife to uncover the screws and carefully pry the cover off the vent pipe.

My Cedar Creek has 3 tanks, one for kitchen, one for bathroom shower and sink, and one for toilet. Shouldn't I have 3 vents?

Sounds like a job for the good ol’ sniff test. Lol

Mine both smell like fresh roses!

That's your call. It's only money! IMO the black tank is typically the one that will smell the worse.

I think he meant he was looking for 3 vents on the roof, one for each tank, but from the other responses, he only has one.

Ever notice that gas/sewer smell around campgrounds in the early mornings and evenings?

Guess where that smell is coming from...

That's right...

The gray tank roof vents of all the RV's in the park that like to keep their gray tank valves opened.

We've been experiencing this pretty bad lately at the RV resort that I live in (park model) as many of the units here have been sitting all closed up all spring and summer long with the water off, and according to the plumber I had out the other day (leaky pipe that was above my pay grade to fix), this is due to the P-traps drying out while nobody was in these units for several months...thus the sewer odor coming out of the septic system through the sink drains and roof vents.

I've also noticed that it gets a little worse when the RV section fills up out front...probably from some of those not keeping their gray tank closed.

I have a 2013 36 ckts. I also have the same 3 vents on the roof. Mine has the 360 style vent on the tank vent. I didn’t take the cap off the two attic vents. We are still experiencing bad smell from the kitchen area. I’ve changed the auto vent under kitchen sink. I’ve noticed smell from the big storage area also. I can’t find anything that’s points to the problem.

I guess all three tanks vent to one tank roof vent? That sound odd, not sure where this smell comes from.....it comes and goes.

I’m thinking about dropping the lower cover and inspect the plumbing
