Black tank vent

[southpaw821]

Anybody else having odor issues... seems like our black tank vent is clogged or something because the smell is so bad.... thoughts?

The smell is bad where?

[southpaw821]

When we flush. Comes out of toilet.. like like the vent isn't working

Do you have the drain valve open?

Are you using a chemical to break down the solids and cover the odor?

Bathroom vent fan on when flushing?

Do you have the fan on? This will suck the fumes out of the tank. Ford and I posted at the same time.

Been there, done that. The black tank is vented so even if the empty valve is closed and you have the fan running, it will pull air back through the tank vent and up through the toilet when you flush. I just turn it off before flushing.
