Smell from the wardrobe and higher cabinet in 21

[LJY]

Hi,

There's a slight bad smell coming from the wardrobe and top cabinets in my 21ft.
They have the black hoses running to the top.. what are they?
Is this smell normal?

Thanks,

That is the vent line from the grey tank. The "black hose" is just a protective cover for the actual vent hose. It goes between the vent stub off the grey tank in the bottom cabinet of the drawer stack, up through the wardrobe and microwave cabinet, to the roof vent.

If you are getting smells, then it is likely you have a leak in the vent hose. I was getting the same thing and traced it to a bad connection in the bottom cabinet. Since the warm air from the grey tank tends to rise, it could be anywhere - just trace the line looking for possible leak spots until you find it.

ps. I had to pop that "black hose" off the vent hose to be able to trace the leak in the vent - the black hose will hide where the leak is. In my case, the leak was where the vent hose connected to the vent stub but the black hose piped it up into the wardrobe in the space between the black hose and the vent hose. Think pipe inside a pipe.

That is the grey tank vent hose. Check up on the roof where it comes out. On mine the caulk around that flexible pipe, under its vent cap needed to be redone. When the vent fan was on it was pulling smells back into the wardrobe.

Reace helped me fix that while he was here doing the hot water pipe replacement.

Eric, do you mean when you were drawing air out with maxxfan? that drew the air from inside the cabinet?

The Maxx fan will pull make up air from where ever it can. If you don't crack or open a window, it will pull from a vent. In my 17, it would pull air from the refrigerator (which had a lousy door gasket) if I didn't crack a window, raising the refer temperature.

In ours it would draw the smell in when running either the Maxxfan or the bathroom fan if we didn’t have windows open enough. Like Jon says the fan will pull air in from wherever possible and the gap in the caulk around the grey vent pipe proved to be one of those places for us, Fixing the caulk gap solved the smell in the cabinet for us. We also now use a lemon scented grey tank deodorant that helps when the bathroom drain is open with the fans on

Hi: thoer... Tanks... Grey is just a lighter shade of Black!!! MaxxFan pulls over 900 cu. ft. a minute. It's gotta pull it from somewhere!!! Alf
