The stench of a noxious sump pump is alarming. Homeowners in Wisconsin want to know whether the stench coming from their sump pump is normal or if it indicates a greater issue. In the majority of situations, repairing a stinky sump pump is simple. A plumber Appleton Wisconsin should be called in certain cases.

Reasons Your Sump Pump Smells

That’s when Tureks, your plumbing company Appleton Wisconsin, enters the picture! We’ve assembled all the details you’ll need to understand why your sump pump stinks. Due to the fact that sump pumps deal with waste, homeowners want to make sure the scent isn’t out of the norm. With these pointers, the distinctions are easily discernible. However, should there be an emergency, please call your emergency plumber Fox Valley.

What Is The Purpose Of A Sump Pump?

First and foremost, homeowners must comprehend the role of the sump pump in their house and why it is critical that it stay odorless.Your Fox Valley Plumber states, because of the quantity of rain that falls in Wisconsin, sump pumps are very vital. What your sump pump performs for your house is as follows.

Sump pumps are used to collect and transport water away from your property. It can accomplish this with both indoor and outdoor water (water you use on a regular basis). The water is pumped from the pump to a safe water disposal facility, such as a storm drain or a dry well. This keeps your basement from flooding.

The sump pump does this by sitting in a sump basin located at the lowest place in your basement. When water or dirt is pushed into the foundation by pressure, the water naturally migrates to the basin since it is the lowest point. The water then exits your house via one-way valve-equipped pipes and into a secure location.

A fan-like device called an impeller also drives water toward the pipe’s sidewalls, creating a low-pressure zone. As a result, the water continues to flow through the pipe. When it comes to water, the longer it sits, the more issues it poses. Your basement will not be flooded if everything works properly.

When some components of the system go unmaintained for an extended length of time, the sump pump scent emerges. As a result, the next time you contact Tureks, put maintenance at the top of your priority list!

What Is That Smell?

When sump pumps have a problem, they might smell like a number of things. These odors may make your basement stink, causing you to avoid it entirely. Here are some of the most prevalent odors associated with sump pumps.


The sump pump may emit a gas-like odor. The odor seems to be gasoline at first, but it is really coming from the sewage. When the sump pump dries up, sewer gas escapes into the house, causing the odor to enter your home. This gas is derived from trash and consists of both benign and dangerous gasses. In a nutshell, be careful of a gaseous odor!


Mildew is a frequent odor associated with sump pumps. Mold and mildew develop within the sump pump because it is continually wet. As with anything that gathers water, you’ll want to keep the sump pump as dry as possible without compromising its operation.


Perhaps you can smell rotten eggs—or, more precisely, sulfur—from your sump pump. Sump pumps are known to emit a bad stench for a variety of reasons, the most prevalent of which being dirt build-up.


Here’s one that’s self-evident: waste. Waste enters the sump pump on a regular basis, which is unpleasant to think about. As a result, waste materials accumulate over time. Clogs may occur as a result of these build-ups. In most situations, cleaning the sump pump is all that is required to eliminate the odor.

Why Your Sump Pump Might Smell

Although the preceding part delves into some of the reasons for a sump pump odor, it’s critical to understand all of the facts. Sump pumps keep your plumbing system clean on a daily basis, so know where to go if anything goes wrong. Some of the most prevalent reasons for a sump pump odor are listed below.

Sump Pump is Dry

Sump pumps dry out after a lengthy period of usage. Because the water no longer covers the air from the gasses, the sewage gas that gathers in the pump is discharged into the residence. In the best-case scenario, this results in a bad odor. Sewer gas leaks, on the other hand, may create health concerns and pose a fire threat in the worst-case scenario.

Water that has become stagnant

Sump pumps catch water before they dry up. For long periods of time, this water rests in the basin with little movement. Mold and mildew thrive in this atmosphere. This growth doesn’t affect the pump’s performance, but it does emit a musty, disagreeable odor.

The Sump Pump is Dirty

Your sump pump’s odor might be due to how unclean it becomes over time. Because the sump pump deals with waste, dirt and other material gather rapidly. Though this may not produce an immediate problem, the build-up over time might develop a blockage.

The Accumulation of Waste

The scent of the sump pump is caused by waste build-up. A sump pump is often utilized in a house, which means it gathers waste on a daily basis. When you use a sump pump for a long time, the waste accumulates. This, of course, produces a nasty odor to pervade your house.

Cracked or Shattered

A sump pump odor, in the worst-case situation, indicates a cracked or damaged section of your plumbing. This component might be found in your plumbing system or on the sump pump itself. In either case, your sump pump will be severely harmed.

How to Get Rid of the Smell of a Sump Pump

We can examine some of the remedies now that you understand the reasons for a sump pump odor. Professional sump pump maintenance is required once a year, but there are several things you can do at home to minimize the terrible odor it generates. Here are some of the most effective remedies for these frequent problems.

Repair Any Cracks or Leaks

Sealing the gaps and leaks is one of the best ways to decrease the sump pump smell, which is comparable to mildew. This applies to all of your home’s plumbing. Check for cracks or leaks in all of your pipes and water systems and cover them with waterproof sealant. Also, look for fractures on the sump pump or in the concrete around the system. This removes any extra moisture that might contribute to mildew or mold formation.

Make Sure the System is Clean

 This solution for a sump pump odor may seem straightforward, but cleaning your sump pump requires both physical and mental effort. The process entails removing the pump from the sump pit (wear lots of protective gear) and cleaning it with warm water. Depending on how much water the environment gathers over time, homeowners should clean their sump pump every six months or once a year.

Bleach Solution That Has Been Diluted

Here’s another way to get rid of mildew odors. To get rid of mold and mildew, use a diluted bleach solution. You just need to pour a little amount of this solution into the sump basin. Even if mildew isn’t to blame for the stench, the bleach solution will assist to refresh the system and decrease smells.

Fill With Water

The simplest solution for a sump pump odor produced by a dry basin is to replace the sump pump. Simply refill with water and you will immediately notice a change! Sewer gasses are always present in the sump pump system, but they are difficult to detect when there is a layer of water on top of them. In a sense, the water filters the gas particles, removing the odor as well as the harmful side effects of sewage gas.


Performing preventive maintenance on your sump pump system is one of the greatest methods to avoid a sump pump odor. You can achieve this by cleaning your sump pump on a regular basis, evaluating the general condition of your plumbing, and having your system inspected by a professional once a year. It’s the most effective approach to eliminate smells!
