Offensive septic tank vent odors emanating from septic vents are produced by
hydrogen sulfide gas. These are a normal by-product of residential septic tank vents
and commercial drain pipes. Ordinarily, this odor would be carried
away by normal airflow and wouldn't be noticed. If your house is
positioned against a hill, or a tree line, these normal air patterns can
be affected and force the foul odor downward onto your patio and
into open windows. The Wolverine Brand Residential septic filter (WLV-4) is the perfect solution.
Stop septic odor with our patented Wolverine WLV-4 (Patent # US 8,273,162) septic filter. It eliminates septic vent odor utilizing a catalytic activated carbon, Sulfursorb Plus. Sulfursorb Plus costs more than standard carbons, and are used by some of our competitors only in their commercial models. These commercial models cost up to 3 times more than the Wolverine WLV-4.
The WLV-4 activated carbon filter comes standard for 1.5" to 4" inch ABS or PVC vent pipes. For cast-iron or copper pipes a no-hub adapter is also required. The WLV-4 easily mounts on top of existing rooftop or yard based septic tank vents to help control that nasty sewage odor. It installs in minutes with no tools required. All you need to do is measure, order and install. That's it! If your home or building contains multiple plumbing vents, you will need to purchase one Wolverine WLV-4 for each vent.
