Check Vents

[Leroy Eckert]

I don't know. Since they are normally closed it seems that something would have
to push on it to open. I rarely have odors in the coach, maybe 2 times in 3
years, once while driving which I attributed to pressure differential while
driving with the drivers window open. I had a small sewer odor this AM after
running the kitchen sink. No exhaust fans were on. That puzzles me as there is
a water trap in the sink drain. As usual, my prints call for seperate roof
vents for the Black and Grey tank, and there is only one. Therefore, I cannot
isolate where it originates, and it happens so rarely there is no trail to
follow. It has only happened when the kitchen sink or shower were turned on.
Soooo, I guess I will get me one of those LilStankers and install it in the vent
line. Those little check vents can be easily removed from the pipe. Inside is a
rubber piece with a white plastic center rod and it is spring loaded closed.
Thanks;

Could they possibly be 'vacuum breakers' Leroy?
