We have a Studor Terminal in an inside hallway closet in our home. Occasionally, when you walk by you can smell the sewer gases, the nice rotten egg smell of hydrogen sulfide. I thought these were a one way air vent system and prevented this sort of thing?

Is it not functioning properly? Should it be replaced? Or can we just permanently seal it up? The model we have, no longer on Studor website is just a beige terminal box with a round hole in the bottom.

Thanks

You can not seal up the pipe unless the fixture it's venting has been removed.
AAV's (air admittance valves) are spring loaded. If the spring is weak or bad it will allow sewer gas to escape into your house. Replace the old Studor Vent with the new type. Good luck, Tom

When the house was first built in the 60's, this closet was once the landry center with a stacker washer/dry unit. There is a faucet box with hot/cold faucets and a drain in the center next to the Studor box. The picture shows the studor box and will assume this is the vent for this closet.

Can I seal off the entry of the drain between the faucets? We don't use this closet as such as we have a proper laundry room in the house now after a previous owners remodel.

Thanks

Hi Paul,
I have good news, This is not a Studor Vent it's a washer box and if it hasn't been used the trap seal's dried up allowing sewer gas to escape.
If the washer box in no longer used then pour a quart of motor oil down the drain to fill the trap and seal it so it doesn't evaperate and let sewer escape.
This trap seal will remain as a permanent seal until you flush it out.
Good luck, Tom
