Service Overview
What Is Sewer Odor Detection?
Quick answer
Sewer odor detection is the process of finding where sewer gas is entering a building, such as a dry trap, a malfunctioning plumbing vent, a failed wax ring or seal, or a damaged drain or sewer line, using fixture inspection and camera inspection as appropriate, so the source can be repaired rather than masked.
Dealing with sewage problems stinks. Once waste is flushed, it is easy to forget about it, but like every other part of your plumbing, your sewer system needs regular maintenance and service to work properly.
If you notice an odd sulfur or rotten-egg odor, it usually points to a problem with your drain or sewer system. What you are smelling is hydrogen sulfide, a gas produced by decaying matter. Because sewage gases can be harmful, it is important to find the cause of any sewer odor in your home quickly.
We are on time, we treat your property with respect, and we use non-invasive methods to locate the source. You will know the total cost of any repair before repair work begins.

Causes
Common Causes of Sewer Odor in Your Home
A dry trap
Every drain has a trap that holds water to block sewer gas. If a drain is not used often, such as in a guest bathroom or a floor drain, the water can evaporate and break the trap seal, letting gas into the room.
A malfunctioning vent
Plumbing vents let sewer gases escape above the roof. If the vent system is blocked or not working properly, sewer gases can be pulled into the home instead.
A damaged drain line
If the drain line between a trap and the main sewer is cracked or damaged, wastewater and gas can seep out, causing harmful fumes inside walls, floors or crawl spaces.
Failed seals
Wax rings under toilets and seals at drain connections can fail, letting odors escape at the fixture.
Why professional help matters
Sewer lines are buried underground and inside walls, so they need proper inspection. Liquid drain products can damage pipes without solving the problem. A camera inspection shows the condition of the line, and repair options are explained once the cause is confirmed.

Why It Matters
Why Sewer Odors Need Prompt Attention
- Health. Sewer gases can be harmful, and leaking sewage carries bacteria.
- Hidden leaks. A persistent smell can mean a drain line is leaking inside a wall, floor or crawl space.
- Simple fixes are common. Many odors come from dry traps or failed seals that are straightforward to correct once found.
- Respect for your property. We complete the work on time and treat your home or business with care.
Quick check: if the smell is near a drain that is rarely used, run water for a minute to refill the trap. If the odor returns or persists, call (619) 374-8554.

Why does my house smell like sewer or rotten eggs?
That smell is usually hydrogen sulfide, a gas from decaying matter in the sewer system. Common causes are a dry trap, a malfunctioning plumbing vent, a failed toilet seal or a damaged drain line.
What is a dry trap?
Every drain has a trap that holds water to block sewer gas. If a drain is rarely used, that water evaporates and gas can enter the room. Running water in the drain refills the trap.
Is sewer gas dangerous?
Sewer gases can be harmful, so the source of any persistent sewer odor should be found and fixed promptly rather than masked.
Why do I smell sewer gas after it rains?
Heavy rain can overwhelm sewer lines or cause backups, pushing gas through traps and vents. It can also reveal a damaged line.
Can a sewer smell mean there is a leak?
Yes. A persistent odor from walls, floors or a crawl space can mean a drain or sewer line is leaking inside the structure. A camera inspection can confirm it.
