What can cause a strong sewer odor inside the house?
The septic odors choking you out are coming from your rooftop sewer and septic tank vents, because that’s the way they were designed.
First, all drain and sewage waste from your house flows into a sewer or septic tank
Secondly, as waste water flows into anydrain, foul, toxic, gas is displaced and must be ventedout the rooftop vent stack, or the waterwill not go down the drain. New and Old, all drain designs minimizeplumbing costs, which although less expensive initially, make sewerodors far more common.
In many areas it in now law that all drain pipe roof vents are fitted with Sweetfilter type activated carbon filter vents when a new house is constructed or when aerated septic tanks are used.
However, they can be installed into existing systems which is often necessary to assure odor free operation of the vent pipe.
There are a number of potential causes for sewer odor inside your house. BE SAFE: Turn off gas and propane sources and get out of the house immediately if there is any possibility of a leak. Do not stay in the house unless and until the problem is found and adequate measures have been taken to ensure your safety. After eliminating gas or propane leaks or any outside source (trash, manure, etc.) as the cause, there are several other possible sources to investigate. Check that the seal around your toilet is not broken. If it is, call a plumber to repair or replace the seal. Make sure there are no broken pipes in your crawl space or basement. Traps for sinks, bathtubs, toilets and drains should contain water. You may need to run several gallons of water down drains and toilets to refill the traps. If you have done any recent plumbing updates or changes, be certain that you have capped off the old lines. Check your vent pipe for obstructions such as bird nests, dead animals or debris. If y
