Watch What Vent Stack Odor Eliminator You Purchase

IT IS Absolutely Illegal In Every Plumbing Code In Every State and In The European Union To Place Any Type OF Valve In a Roof Top Sewer/Septic Tank Vent Stack!
Before you buy a filter for an odor eliminator for your roof top sewer/septic tank vent stack, check them all out. Be sure the one you pick meets all plumbing and building codes.
Remember you system will not operate as it is designed with a valve in the sewer/septic tank stack. The mechanical engineers design the sewer/septic tank venting system to be a sealed system in the buildings but free open venting to the atmosphere. Beware of any system that restricts the original design in all building designs. A system with a valve that opens with the flush of a toilet and closes when operation is complete, does the same thing when you wash your hands, take a shower or bath, run the washer or dish washer, it is opening and closing continuously until it fails. And it will fail!
When it fails, if you are lucky it will fail open to the roof, and the "Rotten Egg" smell, Hydrogen Sulfide (H2$) and other malodorous compounds will vent to the atmosphere, of course now you have the same problem you got rid of for a short while!
But lets be realistic if the valve fails closed to the roof no drain will work. The toilets will overflow when you flush them, what a mess and what an odor. If your bathrooms are on the second floor you will have ruined ceilings, floors and rugs. If you started the dishwasher are wash machine before retiring and you have a basement or lower floor, the lowest sewer opening will overflow. You have a flood.
And worst than that if you or sleeping, the H2S gas has the potential of asphyxiation, especially to a baby, small child or older person.
