A plumber can identify the cause of the scent and then select the problem.

Conduct a Visual Inspection

Begin by examining the areas where the smell of sewers is most prominent or pronounced. Examine for any indications of mold, water damage growth, or pipes that are leaking. Examine the drains on floors, sinks, toilets, and other plumbing fixtures for obstructions or leaks. Be aware of poor ventilation areas because stagnant air may contribute to the smell. In addition, look over the crawl spaces in the basement and the areas around sewer line connections to see if there are indications of cracks, leaks, or other damage.

Check the P-Traps and Drains

P-Traps are shaped like U-shaped pipes that are located under showers, sinks, and drains on floors. They are designed to keep water in place, preventing gases from entering your home. If a trap is dried out, it could let sewer odors permeate. Examine each P-Trap to make sure it’s full of water. Run water through each fixture to replenish the seals and restore the barrier from sewer odors. Also, check drains for blockages or accumulation. Clogged gutters can cause sewer odors.

Inspect Vents and Ventilation Systems

Vents that are blocked could cause sewer gasses inside your home. Examine those vents on your roof and exterior walls to ensure they are clear of obstructions like bird nests, debris, or obstructions. The obstructions in the venting system could hinder airflow and trap sewer gases in the indoor space. If you suspect a ventilation system problem, consider consulting an expert HVAC technician to conduct an extensive inspection and cleaning.

Perform a Smoke Test

A smoke test is a great way to uncover hidden plumbing issues or leaks that could cause sewer odors. The test involves injecting non-toxic smoke into the pipes and observing where the smoke is released. Begin by closing all doors and windows, and then shut off all exhaust fans. Then make sure that all drains are blocked by securing them. After sealing the plumbing system, smoke is introduced via the cleanout or an access point. Look for areas where escaping or leaking could indicate cracks or leaks within the plumbing system.

Why Does My House Smell Like Poop All Of A Sudden?

If you notice a sudden smell of raw sewage within your house, the smell is most likely coming from a drainage system you last used quite a while ago. It could be due to an unclean P-trap. This is a component of your plumbing. It stores a small amount of water to stop the gas from entering your home.

Plumbing Issues

A plumbing issue is one of the most common causes of a sudden smell that resembles poop. Leaks or damaged pipes, drains, and broken plumbing fixtures could let sewer gases escape into your home and create a sour smell. A dry P-trap, a line with a U shape made to catch water and block sewer gases from entering your home, could be another cause. If a P-trap is not adequately maintained or cracked, it can let sewer smells permeate.

Blocked or Clogged Drains

Drains that are blocked or clogged can result in stagnant water as well as organic matter accumulation that can lead to an unpleasant smell that is reminiscent of the smell of poop. Food particles, grease, hair, and other substances can accumulate within drains with time, leading to odors. If there’s an obstruction within the sewer mainline, it may cause sewer gases to flow into your home, which results in a smell. The sudden increase in smell could indicate an upcoming blockage or one that has worsened.

Sewer Line Issues

Sewer line problems could be the cause of the sudden smell of poop. Damaged or cracked sewer lines could release gases into the surrounding soil or your home. The intrusion of tree roots, corrosion, or shifting ground may cause sewer line damage, resulting in unpleasant smells. If you notice that the odor is increasing outside your home or you suspect a problem with the main sewer line, it’s advised to contact a professional to assess and fix the issue.

Ventilation Problems

Insufficient ventilation could contribute to the existence of unpleasant smells in your home. Properly ventilated systems, like exhaust fans and vent pipes, are essential in removing odors and keeping the air fresh. In the event that a ventilation device isn’t working correctly or there is a blockage within the vent pipes, the sewer gases could accumulate inside, which can cause a poopy smell. Regular ventilation system inspections and maintenance are vital to avoiding such problems.

Why Does My House Smell Like Sewer When It Rains?

If you’re experiencing the smell of sewage in your home after rain, the most frequent cause is cracked pipes as well as blocked drains. In the case of trees, the roots often cause broken or burst pipes. Additionally, the origins of trees can damage your septic tank.

Sewer Line Problems

One of the most common reasons behind the smell of sewer when it rains is the problem gases in the sewer line. The heavy rain can inundate the ground and raise the water surrounding your home. If there are cracks or damage to sewer pipes, water can enter this system and cause sewer gases to escape back into your home. This could result in an unpleasant smell in the sewers. Root intrusions from trees into sewer lines are a common problem aggravated in rainy seasons, which can release sewer gas.

Blocked or Clogged Drains

During heavy rain, leaves, debris, and other organic material may build up in outdoor drains or gutters. If these drains are blocked, rainwater might not be able to move freely, leading it to flow back. Stagnant water can transport the smell of sewerage out of drains, which results in odors that permeate your home. Maintaining and cleaning the gutters and drains outside is vital to avoid blocking and issues with odors after rain.

Inadequate Ventilation

A proper ventilation system plays an essential role in preventing the buildup of sewer gases within your home. If your ventilation system isn’t working correctly, rainwater could cause more problems. The heavy rain can result in positive pressure on the sewers, moving sewer gases through drain traps and, eventually, into your home. Ensuring a functioning ventilation system, such as exhaust and vent pipes working correctly and free of blockages, is crucial to avoiding issues.

Dried-Out P-Traps

P-Traps are U-shaped pipes under sinks, showers, and floor drains filled with water, creating a barrier between the living area and your sewer line. This barrier stops the sewer gases from escaping your home. In dry seasons, they can dry out, which allows sewer smells to permeate your home when it rains. The process of running the water over these pipes frequently or regularly pouring water into drains that are not used can help to maintain the seals of the water inside the P-Traps. This will prevent the smell from entering your home in the event of a rainstorm.
