venting septic tank gas
Posted by james r on December 03, 1999 at 13:16:33:
I live on top of a mountain and under certain conditions, usually unseasonably warm fall and winter days, the gases vented through the roof seem to settle onto my back deck. There is no smell whatsoever in the house or attic. I have been told that certain atmospheric conditions together with wind direction from the opposite side of the house can drive these gases downward. If this is so, what can be done about it? extend the vent pipe upward? install a fan? What else might be the cause, e.g., a problem in the septic system?
