In a recent thread, someone noted that there were several
remedies for dealing with this problem, but I don't think anything
was ever specified. Could someone provide a bit more detail?
I live in Maine and there are three vents to the septic, one
in the field itself, the second over the tank, and the third at the
end of the line to the house (all are comprised of plastic pipe.)
This is a small cottage, and the single end-of-line vent is
allowed in Maine.
It appears the odor is emanating from either the tank vent
or the line vent or both. The tank vent has the familiar "cane" shape,
and the line vent is simply an extention of the line which runs up the
side of the house and extends about two feet above the roof line.
I would suspect a chemical could be added to the tank. (Could
someone suggest a brand?) The other I remedy I have seen
involves charcoal filters which could be placed over the tank
vent or the line vent or both, but I wonder about their efficiency.
Also, do they last indefinitely or does the charcoal have to be
Your help is much appreciated!
I'm also in Maine and we must have had our systems designed by the same
Look at the qualifications for a person to design septic systems in this
state and you'll be amazed.
I resolved the odor problem by plugging all vents except the roof vent.
The vent over the tank and the one at the end of the field are redundant.
Do a google group search on Septic and vegetable oil. What a can a of worms.
I am in no way advocating you do it. I bring it up just as a reference point
in that this discusion has occurred before. I belong to the "no fat in the
septic" school of logic (regardless of how many baffles you have).
Charcoal filters (must be activated charcoal to do any good) need to be
replaced. Remember they work because they adsorb the particles that
cause the odor sensation on the large surface area created as the the
charcoal is "activated." But, once all of the surface area has odor
particles attached it needs to be replaced.
If by stack you are referring to something at roof level or above I'd
not do anything. Must gases that you are smelling are lighter than air
)methane) or only slightly heavier than air (hydrogen sulfide) and will
Maine's regulations are laughable. The order most follow is septic
system first, then well. There are regulations that force the septic
system to be place a prescribed distance from any well (I think it's 100
ft.) but a well can be placed anywhere. So if you need to, install the
septic system and then drill your well right in the center of the leach
field. Crazy, but satisfies the bureaucrats.
