Frequently Asked Questions

To properly absorb all errant odors, you will need one Wolverine septic vent filter for each vent in your system.

All of our passive and low flow filters fit standard pipe without any adaptors. If your home or business uses an old cast iron pipe or copper pipe you will need a no hub adaptor. You can visit our How to Measure Page for a “how to” on measuring your septic or sewer vent.

Yes. Instructions can be found on our Support Document Library Page.

The life expectancy of your Wolverine is dependent on how much sewer gas is produced at the location of the filter. Generally they will last 2 to 5 years. The Wolverine by design holds between 1 to 2 pounds of Sulfursorb depending on filter size. This is up to three times the carbon of other septic vent filters. This is what enables us to have a warranty that is 30% longer than the competition!

You have two options if you find you ordered a filter that is too small to handle your H2S load.

• You can buy extra carbon to keep on hand
• you can purchase a larger adsorber. We will send you a 20% rebate If you send us your old filter.

The Wolverine septic vent filter will only solve odors that originate at a septic or sewer vent or any volatile organic compounds (VOCs). The gasses that cause septic and sewer odor must pass through the filter in order for it to absorb the gasses.

The Perforated disc at the inlet of the filter reduces the inlet size by 50%. This will not cause a problem with a passive vent system. If you are concerned and wish to keep the same inlet surface area you can utilize a larger size Wolverine and use a reducer at the inlet to attach the filter to your plumbing vent.

Vent pipes can occasionally clog up with frost if it is cold enough for long periods of time. This is called "hoarfrost". All Wolverine filters (except inline models) are designed with cross through ventilation to wick away the moisture that naturally occurs at a vent to help reduce the possibility of freezing in freezing temperatures. If you are in an area of extended below freezing temperatures you may want to consider choosing our Inline Wolverine. This style filter is mounted in the attic, away from the elements, and comes with an insulated blanket for added protection. NOTE: The Inline Wolverine requires removal of a section of vent pipe. For this reason we recommend that it be installed by a professional plumber.

The MT-20 is good for vent airflows up to 20 cfm, our MT-30 is good for vent airflow up to 30cfm and our MT-50 is good for vent airflow up to 50 cfm. If the vents airflow is higher than 50cfm you would need a pollution control barrel.

All of our Manhole inserts and Inflow protectors carry a 1-Year Warranty.

Due to the large variety of manholes used each manhole skirt and inflow protector is cut to fit the measurements you send us. You can find the measurement sheet here.

Utilizing a water inflow protector for odor control will stop the odor at the manhole you have installed the inflow protector in, however the gasses will be purged at the next available exit point of the sewer system. This is very often a building vent or another nearby manhole cover. In effect you have only pushed the problem downstream to another location.

No, This is one of the few products that we do not manufacture.

All you need to know to select the proper adsorber is the CFM flow of your system and the concentration of the H2S in the airstream. Click here to learn how to calculate the CFM of the air and the concentration of the H2S. Once you have those numbers, click here to calculate the vessel size you will need.

Yes, Choosing the size larger than the recommended unit will not cause any problems with the operation of the system.

The industrial Vapor phase adsorber comes with a 1-Year limited Warranty.

The differential pressure gauge indicates the resistance of the air flowing through the carbon bed. On startup, this is a good way to check for the required air flow rate by observing the pressure drop reading. When recorded over time, the pressure drop history can indicate that problems have developed such as particulate or grease contamination. Pressure drop DOES NOT indicate that the carbon is spent and has to be replaced - only testing can show that breakthrough has started and the carbon needs to be replaced.

We do offer ono-site installation. We are also actively seeking installers in all states.

Yes, we do offer onsite start up/setup of the system.
