Best Sewer Gas Detector (Rotten Egg Smell in House)

Gas leak detectors are devices used for sewer odor and sewer gas detection. They can help in identifying the presence of a potential gas leak. Sewer smells in bathroom and sewer smells in homes are common. Sewer gas leak detectors can be useful in the identification of combustible gases and many such detectors have the capabilities to identify several gases common to sewer gas leaks that includes ammonia, methane and hydrogen sulfide. They are particularly helpful for plumbers, inspectors, water works, HVAC, contractors and maintenance engineers.

Pros

Cons

  • Sewer gas detectors can monitor the presence of combustible gases commonly found in sewer gas.
  • Sewer gas can be harmful and potentially fatal if left unaddressed for too long.
  • Sewer gas detectors are relatively inexpensive and affordable.
  • Sewer gas detectors can be purchased and used by the average homeowners to find sewer leaks.
  • Some high-end sewer gas detectors can be very expensive and inaccessible to some homeowners.
  • Gas leak detector is a broad term that may be misleading in which gases can be detectors-- homeowners may accidentally purchase a detector that does not monitor the gases of interest in sewer gas.
  • Fixing gas leaks may require the use of a professional. Other methods include smoke testing and acoustic testing.

What is Sewer Gas?

Sewer gas is composed of both toxic and non-toxic gases such as hydrogen sulfide, ammonia, carbon dioxide, and methane. It is a natural by-product of human waste and becomes a problem for homeowners when there are leaks, clogged vents, and/or broken pipes. Most term this the rotten egg smell in house, found commonly in older sewer plumbing and building.

What is a Sewer Gas Detector?

A Sewer Gas Detector is a electronic handheld device that has a gooseneck with a sensor. The sensor detectors sewer gas coming from your drain in your shower, bathroom or kitchen. The sensor changes electronic signal and sent to the display showing you the gas concentration level detected.

Why Does My House Smell Like Sewer?

Sewer gas is produced as a result of household and industrial waste. In includes a mixture of several different gases from the decay of such waste. When you smell sewer gas in your home it means you have a leak, the gases are accumulating to the point where your nose can smell it. 

Can Sewer Gas Cause Health Problems?

 Yes.

Sewer gas has the potential to cause both minor and serious health effects, as the Wisconsin Department of Health Services details, including:

  • Hydrogen sulfide poisoning: This poisoning irritates the eyes and respiratory tract and can cause death at high concentrations.
  • Asphyxiation: The presence of methane can suffocate and cause death when the methane displaces large quantities of oxygen.
  • Burns: Flammability of certain gases in sewer gas can cause burns to individuals who encounter these fires.

Symptoms to look out for if exposure to sewer gas is suspected include the following:

  • Headache
  • Nausea
  • Dizziness
  • Drowsiness
  • Nervousness
  • Unconsciousness

Will Sewer Gas Explode?

Sewer gas does have the potential for creating both fires and explosions due to the presence of certain flammable and unstable gases in the mixture. Gases of particular concern include hydrogen sulfide and methane.

What is the Rotten Egg Smell (Sulfur Smell) in My House?

If sulfur is smelled in the house, there could be two potential explanations and sources of the rancid odor. First, it could be a sign of a natural gas leak. This can occur in the case of a substantial natural gas leak. The second explanation for this distinctive odor is that it could be a sign of a sewer gas leak-- such gas does contain some toxic gas components including methane and hydrogen sulfide.

What Does It Smell Like if You Have a Sewer Gas Leak?

In most cases, a sewer gas leak will have a strong sulfur smell which can often translate into a smell reminiscent of rotten eggs. This is primarily due to the presence of sulfur in sewer gas through the gaseous component, hydrogen sulfide.

Does a Gas Leak Detector Find the Sewer Gas Leak?

The first step to finding the source of the smell of sewer gas in the home is the use of sewer odor detection. This can be accomplished with a sewer gas leak detector. Other methods include calling in a plumber and he will undertake a smoke test to assess where, exactly, the leak may be in the pipes and also undertake a acoustic leak test.

The cheapest way for a landlord or homeowner to track down a sewer gas leak is to use a Sewer Gas Leak Detector.

Is There a Device to Detect Sewer Gas?

A combustible gas leak detector for sewers is a piece of detecting equipment that can be used in order to monitor the presence of multiple kinds of combustible gases that are commonly found in sewer gas. In most cases, these devices will alert the user to the presence of specific types of gases, such as hydrogen sulfide, but not have a broad "sewer gas" detection as a whole.

Instead, the user must be equipped with knowledge of which gases are commonly found in the mixture of gases included in sewer gas and deduce from the combustible gas leak detector whether or not those gases are individually present in a given area.

What Are the Best Sewer Gas Detectors?

Some examples of effective sewer gas detectors include the following:

How Much Does a Sewer Gas Detector Cost?

A sewer gas detector ranges from $30 to $300. The Forensics Detectors Gas Leak Detector costs $95.

How Long Does a Sewer Gas Detector Last?

A sewer gas detector lasts for over 5 years. 

Does a Carbon Monoxide Detector Detect Sewer Gas?

No, it does not.

Carbon monoxide detectors DO NOT detect sewer gas. These devices are designed to detect only the presence of carbon monoxide, and thus will not pick up on the other gases that are found in a sewer gas mixture.

Is My Nose More Sensitive Than a Sewer Gas Detector?

Yes. The human nose is more sensitive than a ppm type of gas leak detector.

The problem however is that the nose changes sensitivity once it smells a rancid smell such as sewer gas in the home. A process called olfactory fatigue reduces its sensitivity, and as such, is not a reliable objective detector.

So in other words, a sewer gas detector is more effective than the human nose for identifying a sewer leak and a much more objective instrument.

What Gases Does a Gas Leak Detector Recognize?

Gas leak detectors can recognize a variety of gases, especially if they are used in the broad sense. Combustible gas detectors can recognize combustible gases, as their name suggests. The Forensics Detectors Gas Leak Detector is intended for combustible gases and, as such, can detect combustible gases including the following:

  • Acetone
  • Acetylene
  • Alcohol
  • Ammonia
  • Benzene
  • Butane
  • Ethanol
  • Ethylene
  • Oxide
  • Gasoline
  • Methane
  • Hydrogen
  • Hydrogen Sulfide
  • And more

Many gas detectors that are marketed as combustible gas detectors are be able to detect the same gases - combustibles. 

Does Lowes Sell a Sewer Gas Detector?

Yes, Lowe's sells gas leak detection solution and a digital multimeter with the capabilities to detect a number of combustible gases that are found in sewer gas.

Does Home Depot Sell a Sewer Gas Detector?

Yes, Home Depot sells multiple types of combustible gas detectors. Several of these devices have the capability to detect multiple gases found in a sewer gas mixture.

How Do I Get Rid of Sewer Gas Smell in My House?

There are several steps that should be taken to remove sewer gas odor from the home. To start, clean the sink overflow, address the toilet by checking the wax ring and caulking the base, remove bacterial growth from drains, check plumbing systems that are not used frequently, check the garbage disposal, and check for any potential leaks in pipes. The last step on this list may require the assistance of a hired professional if the homeowner is uncomfortable with identifying holes on their own.

What is the Main Cause of Sewer Gas in a Home?

 The main causes for sewer gas odor in the home include the following:

  • Leaks
  • Cracked pipes
  • Air vent blockage
  • Drain clogs
  • Dry plumbing
  • Loose toilets

Final Words

  • A sewer gas detector may also be called a combustible gas detector, sewer gas leak detector, sewer odor detector, sewer gas detector of the home, or combustible gas leak detector for sewers.
  • Long-term exposure to sewer gas can be dangerous and even life-threatening.
  • Sewer gas detectors can provide homeowners with a means to test the presence of sewer gas in their homes if they smell sulfur.
  • Sewer gas leaks can be fixed by hiring plumber. They will find and fix the leak, that is usually caused by old, defective and degrading plumbing infrastructure.
