Sewer Smell in the Basement Why and What to Do?

We can all admit that sewage gas is one of the most revolting odors known to mankind. This odor may swiftly infiltrate your house for different reasons. Not only is the odor awful, but it is frequently an indicator of a far more serious problem!

As a result, it is critical to comprehend why your property, particularly your basement, stinks like a sewer. What is the deal with my basement smelling like a sewer? The most typical cause of a sewer-like odor in a basement is an issue with the floor drains or drains in basement appliances such as toilets, sinks, or washing machines. Sewage odors in the basement can also be caused by improper air circulation or, in the worst-case situation, sewer line disruption.

Sewer Smell in the Basement? Why and What to Do

A strong sewer odor in your basement is usually produced by a clogged floor drain, a faulty ejector pit seal, poorly ventilated equipment or fixtures, or even a broken sewer line.

Ejector Pit and Pump

If your property has an overhead sewer line in the basement, the ejection pit must be properly ventilated and covered with a cover to hold the waste water. A damaged or blocked vent, a misplaced lid, or a faulty seal may soon fill your basement with sewage gas.

Quick Fix

Ensure that your ejector pit (if you have one) has a well-fitting cover with a good seal. Examine the waste outflow and vent pipes for cracks or clogs. To keep the sewage odor at bay, change any parts as required.

Floor Drains and Dried Traps

Do you recognize what the U or S-shaped pipe under your kitchen or bathroom sink is for? That curve in the pipe has a purpose. Its goal is to retain a little volume of water in the pipe at all periods so that sewage gas does not invade your household through the line.

These water traps can also be found beneath basement floor drains and laundry tubs. Water traps might dry out due to inactivity since water evaporates in any disused drain. When this happens, sewage gas may enter your house.

The sewer stink is usually caused by infrequently used floor drains in your basement. These drains have a trap that holds a tiny amount of water in order to seal the pipe and prevent sewage gasses from entering the residence. As the drain dries up (condensation, etc.) from infrequent usage, the seal might crack, allowing sewage gas into the basement and reeking it up.

Quick Fix

Pour about one gallon of clean water through the drain to seal up the pipe and prevent the stink from entering your basement. If you feel like, add a mild household cleaner to the water for a fresh scent. This also pertains to infrequently used toilets. If the water in a toilet bowl has run dry, then flush the toilet once more.

Drain Stopper

Most floor drains also have an internal cleanout stopper that is not always changed. Without such a plug, sewage gas can enter your basement directly.

Quick Fix

Lift the grating on the drain hole and check for a misplaced plug. New plugs are available at almost any hardware shop.

Vents

Basement fittings and equipment are not often adequately ventilated, allowing sewage gasses to enter the property.

Quick fix

Ensure that the laundry facilities and bathrooms are properly ventilated and connected to the rest of the house. This extends to the entire house; odors from the main or upper levels can occasionally make their way to the basement.

Sewer Line

The sewage odor you are smelling might be caused by a broken sewer pipe. If this is the scenario, and the leak is close enough to your house, the contaminated water will leak into the earth and find its way to your basement’s drainage pit.

Solution

This is best done by experts. The most frequent repair approach includes using a leak tracing dye and passing it down the tub or toilet to determine if the coloured water reaches the soil. If a leak is discovered, the next step is to pinpoint the source of the fault, which will decide how much effort is necessary to fix the leak.

In conclusion, avoid ignoring the sewage odor in your basement at all costs. It is not only bothersome, but it may also lead to major health problems such as pneumonia and bronchitis. It is also combustible since methane and hydrogen sulfide are both explosive. I hope you found my article helpful. Feel free to drop any queries or suggestions in the comments section below!
