I have a question about the odors that come out of the vent pipe of a septic system.
I have a house that has a septic system. I had the septic tank pumped out two years ago when I first moved in. I have noticed that on some days, there is a slight sewage smell on the front of the house after a shower/flush/wash cycle. I have determined that the smell does not come from the septic tank or the drain field directly, but rather from the gases coming out of the vent pipe on the roof. These gases come down the roof to the front of the house. The house is on the less windy side of a mountain and is surrounded by trees.
My question is: Is this smell normal, or is it a sign of a problem with the septic tank? Looking around the web, I have found articles that say there shouldn't be an odor coming from the vent pipe, and other articles which say the smellis normal and can be minimized with a filter.
Thanks for any advice.
