I just bought an old farmhouse an am going thru all the repairs that
need to be done and have a puzzle.
when a large load of waster is flushed down the pipes (i.e. bathtub
emptying) the basement fills with septic gas. found a cleanout cover
rusted out (and now fixed) but still having the gas.
I'd say that when the water enters the tank, the gas gets pushed back,
after the fix it has dropped noticeably, but it appears it has now been
directed to the tank vent.
still some gas in basement, and a fairly good stinker from the septic
vent, have i been living in the city soo long to forget that this is
forgot to add some pertinent information......
darin feild outlet seems to be draining correctly, tank was pumped out
before purchase (paid for by me) and the house was not ocupied for
approx 6 months before we purchased.
and some websites say that chem treatments are nothing more than snake
oil. aside from that SWMBO purchased a bottle of such stuff to see if
it does work or not.
Shortly after I bought my present house, I also found a rusted cleanout
cover. I replaced it and that stopped the sewer smell in the basement. I
do get sewer smell whenever my wife does laundry but only in the back yard.
I believe, however it is coming from one of the roof vents as my septic tank
has no vent. I lived in the city for 17 years and had also forgotten that
these things come with country life. We live with a pretty constant wind
from the West that after going over the house is backdrafted down behind the
East side of the house, thus I believe why the smell is in the back yard
when laundry is done. If you're still getting smell in the basement,
perhaps you have a plumbing trap that is empty of water, thus letting the
sewer gas through.
I remember a year or two ago, there was a poster who had a mansion
house with many rooms. He was complaining that his house often filled
with sewer gas fumes and smelled like sh*t..
The solution was simple. He walked thru the empty rooms once every
day or two and ran a cup of water in each drain and refilled the
'traps' which blocked the sewer gas.
I've found vents hidden inside walls, someone took a short cut and used
pvc one way valves in an attempt to make drains work better. That might
be alright at first (though I doubt it would pass code), but if the
rubber flap or what ever makes it one way fails you have an open pipe.
Vents like these are supposed to be on risers that take them up into the
attic so that they can be serviced.
In theory, you can bring all vent pipes to a single vent trap like this
and run a single penetration of the roof.
