Vent for an exterior sewage ejector pump?

[polar8]

I have a sewage ejector pump right outside my house. It receives the sewage from my garage, which was too far away to do a gravity drain.

The basin I got has a hole for a 2" vent, and I'm just going to have a short section of pipe sticking out of it. I'm trying to figure out how to properly vent it without having to smell the contents of the basin.

Is this what I want? https://www.supplyhouse.com/Oatey-3...isuH2cTUq1DBM5LnYDvUCPkxErJpZF9QaArq9EALw_wcB

All you need is a vent pipe going up above the nearest roof.

All you need is a vent pipe going up above the nearest roof.

It's kind of in a visible location and I'd rather not have such a long run of pipe. Is that possible or against code?

Is this a new installation of the pump? Some municipalities do not allow the Air Admittance Valve (AAV). I would check with your local building department.

I temporarily had my washer connected in my covered patio and used the Oatey valve and it worked good.

I would not recommend that activated carbon filter thingy.

The best bet is to vent through your roof. Second option would be the AAV.

Maybe you could duct the vent into the living room. When you have a moment of indiscretion you could not blame the dog, as is the custom, in some states. The dog will thank you for NOT having to feel your guilt.

As others have said a vent to the top of a nearby roof is the best if that is not feasible the charcoal filter at ground level would be the next choice.
The AAV valve will not work in this instance as it will only let air in to the chamber when the pump is on and the chamber is being emptied ''It only works when there is a vacuum condition not a pressure condition''. Air also has to go the other way out of the chamber when it is filling up with sewage. Some air may go back up the top half of your inlet pipe as the sewer is coming down the bottom half of the pipe but this is conditional on the orientation and grade of that line from the chamber til it exits your roof.

I'd just put the vertical vent riser up a few inches, with a 180 degree sweep at the top turned down , with a piece of hardware cloth over the opening to keep critters out of it.

If You do not care about smell you can keep the vent short.
If you do, you need height.

If code allows you can try it short to start and go higher later if it smells.
