    Hi all!
    This is my problem.
    My neighbor's house has 3 waste vents thru the roof. 2-2" and 1-3", all pvc.
    This house is about 60+ years old, and has remodelling done.
    She does not live there full time,And has not for 20 years since she purchased the place.
    She is maybe there 2 weekends a month at max, but at times not there for 6 weeks.
    Septic tank was replaced about 10 years ago.
    At any time of the year, and which way the wind is blowing, it smells bad around the outside of the house.
    I know it's coming out of the vents cuz I got on the roof and put my nose near the vents.
    I am the caretaker, so I check the house everyday, and also run water in the sinks and toilets couple times a week.
    The main waste lines, 3", are all pvc, and branch out like a "t" through the foundation. One line is about 45' long and the other is 50-55" long.
    There are no traps in the main lines, to the septic tank, just clean outs.
    So!, How can I stop this smell outside the house!
    Can I get some AAV and put on the vent stacks? Help please!
  2. Sorry, but constantly venting sewer gas is what vents do, for one thing.
    If you're down wind of the prevailing wind there, there isn't a lot that you can do taht I know of. (I'm not a pro plumber, just a long-time DIYer.)
    You might try putting extensions (unglued) on the vent pipes to see if that helps. Raising the height a couple of feet might help the wind blow it away.

    With the advice you give about septic systems I certainly hope you are on a sewer now!

    Rid-X is a totally unnessary product. The bacteria occurs naturally in a septic tank and does not need any bacteria added to it!

    Strong doses of bleach should be avoided with septic system as it has a sterilizing effect and can kill the bacteria in the septic tank... In which case you would need Rid-X

    I'm wondering if the septic tank doesn't need cleaned. Also, I wonder if the baffles in the tank have broken. If no one is home, maybe the bacteria are having a field day and if there is no obstruction, the gas can back up through the line. Or perhaps the water level in the tank is too low. (Cracked tank?) In normal use, a septic tank has either baffles or pipes on the ends that would trap the air in the tank while allowing the water to flow through from the middle portion of the tank.

    As I said in the post above I sincerly hope you are on a sewer and not on a septic system!

    Before you get on a septic system again it would behoove you to visit this site linked above and learn about septic systems. The misinformation you are giving out could be costly to a septic system owner.
