Changed all of the vents I could find in our coach. I found 4 total. Found 2 in the closet behind our Splendide, one under the kitchen sink and one under the bathroom sink behind and underneath the drawers. The new vents have spring loaded flap and the olds were free floating flaps.

John,
I did that on our coach, replaced EVERY ONE I COULD FIND. Since I have no sense of smell, I kept getting complaints about odors. Turned out there were two buried behind the paneling in the closet for the washer/dryer that had been removed.
Hope you found all of yours!
Happy trails!
Len
Len, We found 4 total.

If you have the hamper cabinet behind your toilet, check for one there as well.
Do these keep the black and grey tank smell from entering the coach, while still letting air in so the drain can drain?
What was the model number you purchased?
Chris
Yes,
Also known as AIR ADMITTANCE VALVES. Oaltley is one of the main manufacturers of these valves.
Michelle,
I looked in there and didn't find one. My closet is directly behind the hamper and my Splendide is inside there. I found 2 in there behind the clothes washer dryer. I'm assuming one was for the clothes washer and one for the toilet.
