: Carbon filters work well to relieve the hydrogen sodium sulfide gasses that cause the "rotten egg" odor from septic systems. The problem might simply be rectified by extending the vent, though. If the vent is lower than the peak of the roof, and the prevailing breeze passes over the vent and then rises over the roof peak, but is then drawn back down to the ground by air currents, it hasn't had time to dissipate the concentrated gas in the atmosphere before you smell its offensive odor. Check with your local building or health department about code requirements before extending the vent.

: : We just had a new septic system installed and now our yard and house carries a foul odor that seems to come and go and move about. It was difficult to track down the source, but it seems to be coming from the septic vent on the roof of the house.

: : The installers of the septic system suggest we put a cap on our vent with small holes drilled in it to reduce the airflow. I'm concerned that this will affect how our toilets flush.

: : I've also seen carbon filters for this purpose -- do they work?

: : Any other suggestions?

: : Thanks!
