Here we focus on sewage or septic odor problems that occur during cold weather or wet weather. We also discuss causes and cures for sewer gas odors related to wet or cold weather. Sharon when there is a sewer odor in the neighborhood, if your homes are on private septic systems I suspect someone's drainfield is in failure.
If we're talking about a community where every home is connected to a municipal sewer, there could be a burst line, effluent breakout, a problem with a pumping station, or the odor could be from something else. I would like an opinion.
I have a cesspool, it has been pumped out even though the gentleman said it did not need it. Every time we have heavy rains in our area I get a foul smell inside my home. I had it pumped thinking that was it but the cesspool man said it was not. Can you give me any idea of what it might be the system was installed in and even though old still works perfectly with this one exception.
Rain could be flooding the cesspool, causing a breakout of septic effluent and odors - more likely if that were the case the odors would be strongest outdoors at the cesspool; It would be stunning if there were a cesspool that was still working. We moved into a doublewide in western NC last March.
We noticed, mostly late evenings and early mornings, a really bad sewer smell.
Our landlords said that sometimes, as a system gets used to new people and new system uses, it can be a little smelly. Anyway, soon, spring and then summer arrived and the smell had gone away completely.
At the very first sign of fall, however, the smell has returned. Now that all of our nights are in the 40's or below, we are smelling it again every morning and evening, but not during the heat of the day when temps reach the 70's. There is no smell coming from inside the house, only what drifts in through open windows.
How To Make Your Own DIY Composting Toilet
Everything seems to drain fine in the house. Totally clueless and really frustrated at this point. Jeff, That's a new one on me - I don't think septic tanks and drainfields know who is using the system.
There might of course be a difference in the level of usage - if the new occupants are using more water or if there are more occupants than previously, that may be causing a septic failure to show up.
The fact that you smell odors outside only sounds as if there may be a failing septic drainfield. I hope that some help be given as we are at our wits end. I have and unfinished bathroom in the basement and we are haven s sewer smell that is very prominent in the unfinished bathroom. Laila I'm not sure what is the state of affairs in the new bathroom, but here are some possible reasons you'd smell sewer gas there: 1.
If you have an open drain line without a trap, such as a mount for a toilet, sewer gases would come out there - use a rubber plug or a large rag to stuff that opening until a toilet is ready to install.
Don't let the rag or opening-closer fall down into and clog the pipe however. If you have fixtures like a sink or tub or shower that are installed and have plumbing traps but they have never been used, the trap will be dry and sewer gases can come out at those points. Just pour some water into each trap to form a seal. A cup or two will be plenty. If you are not going to use the fixtures anytime soon you can pour in clean mineral oil instead.
If fixtures were installed improperly you could have a leaky toilet wax ring seal 4.To figure out what might be causing that awful smell, it helps to have a basic understanding of how the plumbing in your bathroom works.
Don't worry -- this will be quick! At some point, you've probably looked under the bathroom sink and noticed the U-shaped pipe that runs from your sink drain B to a larger wastewater pipe in the wall. This pipe is called the P-trap. One end of the P-trap runs down to your sewer or septic system E ; the other end leads all the way up through the roof Dletting fresh air in while allowing any smelly sewer gases to vent out to the sky.
And although you can't see it, the same basic drain setup is at work behind or beneath your tub and shower C. The U-shape of the P-trap allows it to collect a small amount of water after each sink use, which acts as a barrier against sewage odors.
When everything's working as it should, the water stays in the P-trap after you turn off the sink, empty the tub or flush the toilet.
That little bit of water is enough to prevent gases from drifting out of the sewage system and into your house. Under normal conditions, those gases flow right past your bathroom and out through the vent pipe in your roof [source: Wm.
Henderson ]. Traps are there to prevent sewer gases from escaping into the home. Failure to properly vent those stinky gases has the potential to be more than just annoying. Methane is the largest cause of sewer smell but there is also danger of hydrogen sulfide, carbon dioxide, ammonia, nitrogen oxides and sulfur dioxide," explains Patrick in an email interview, adding that the main culprit of such added toxins are people disposing of gasoline and other chemicals down their drains.
Signs of exposure can include dizziness, headaches, nausea and drowsiness. Clearly, it's important to figure out exactly what's causing the sewage smell and make sure it's corrected quickly and effectively. If you're lucky, it will be one of the easy fixes on the next page.
How to Keep Your Toilet Clean. How to Prevent Odors in Toilets. Prev NEXT. Plumbing To figure out what might be causing that awful smell, it helps to have a basic understanding of how your bathroom plumbing works.A smelly shower drain is a definite sign that something is wrong in your bathroom. Bacteria in the shower drain feed on the debris in it and emit a bad smell in the process. That is one of the main reasons why your shower drain smells like a sewer.
A dry P-trap and short vent pipes can cause rotten-egg like smell in the bathroom. Thorough cleaning of the shower drain and fixing the plumbing problems usually gets rid of the bad smell. Before you mistake the smell for the sewer line having burst, you need to know that the smell occurs due to a lack of thorough cleaning of the shower drain.
Anaerobic bacteria feed on the dirty water in the drain and emit hydrogen sulfide gas. This gas is what smells like sewage or rotten eggs. Your shower drain receives a lot of debris from soap, hair and all other sorts of dirt in your bathroom. While a large part of this is washed down, some of it is retained in the drain and the piping system.
Anaerobic bacteria will work on it releasing various gases among them hydrogen sulfide which smells like sewer gas. The damp conditions in the shower drain are perfect for the growth of microorganisms such as bacteria and fungi. When mold, a type of fungi, grows on the inside of the drain, it will cause a musty stink.
This smell combines with other odors from the plumbing system to form a sewer-like smell. There are types of fungi that break down soap into sulfur compounds, one of which is the sewer-like hydrogen sulfide gas. The shower drain has a lot of debris from the compounds found in soap, hair and body products, and general dirt.
Coupled with the dampness, bacteria and fungi will act on the dirt, breaking it down into individual compounds and elements among them sulfur and its compounds. This smell is felt mostly when showering as the water displaces gases upward and outward into the shower room. If the vent pipe is too short, the sewer smell will find its way into your home. It is likely the unpleasant odor is coming from another part of your house and diffusing into the shower area.
For example, the sewer smell could be finding its way into the bathroom through the sink drain. You might want to check all the areas with possible leaks to rule them out.
8 Highly Dangerous House Smells That Should Not Be Ignored
Sewerage piping needs to be airtight. The common areas to check include the toilet wax ring, P-trap nuts, shower valve, pop up stopper of the sink drain, and the gooseneck.
As the sewer pipes get old, they rot or crack and start to let in the stink into your home. This is highly likely in old homes. Plastic plumbing can be eaten away by rodents while metallic ones rust and start wearing out. Any leakages in these systems can dump sewer gas into your bathroom. Routine checks will ensure they do not get into this condition without your knowledge.
This wax ring keeps the sewer gas away from entering the home from the sewerage system. If it wears out, you will feel the bad smell in the toilet or bathroom. When the sediments in taps dry up, they will emit sewer-like smells into the bathroom or other places they are located. The P-trap is the U-shaped part from the toilet bowl to the water cistern.
The water trapped in this part keeps away sewer gases from coming back up through the pipes to the toilet bowl. If dry, the gasses will freely come back up. In some cases, the anode rod in your shower heater may react with the chemicals such as chlorine in the water leading to the foul smell.
The best way to test this is to sample both cold and hot water from the shower. If the hot water has a sewer-like smell, then the problem is with the anode rod in your water tank.Sewer gas smell often comes from a floor drain like this one. This is a floor drain inside a Men's Room at a hotel.
Under the metal grate is a water seal you can't see. Water evaporates allowing the gas to enter the room. Custodians and cleaning personnel need to pour a gallon of water into floor drains like this at least once a week. Copyright Tim Carter. Sewer gas smell is caused by invisible gas that enters your home from your plumbing pipes. The most common source is dry floor drains. The second-most common source is a bad wax seal under a toilet.

Use the following audio player:. The odor is strong when it rains and the furnace or air conditioner is operating. The odor gets so bad my daughter and her family evacuate the house. Three plumbers have not been able to solve the problem and we have checked all plumbing fixture traps, caulked where the basement floor meets the foundation, etc.
My daughter is ready to sell the house for a loss. Can you help? Dave S. As much as I hate to say it, the three plumbers that were consulted are either inexperienced or they do not keep up with technology.
The good news is I doubt your daughter has to move and take a loss. It is my guess the source of the odor can be found and repaired for less than what a moving company would charge just to move your daughter and her family.
I've been a master plumber since age 29 and have solved hundreds and hundreds of sewer gas problems.
Sewer gas smell can enter a room if the water level in a toilet bowl drops this low. Always keep the toilet bowl filled with water to its normal level. Sewer gas is created by the decomposition of waste materials that are found in public and private sewer systems and private septic systems.
The characteristic odor can be overpowering and it is toxic. To add further insult to injury, the gas is explosive as it often has a methane component. Plumbing drainage systems are designed to keep this sewer gas inside the pipes and any that does exit to the atmosphere happens outside the home through the vent pipes that poke up through the roofs of houses.
Vent pipes on the roof are intake vents, not exhaust vents as most people believe. When a large volume of water enters a plumbing drain pipe it pushes air in front of it towards the sewer or septic tank. This air must be replaced and it is sucked into the plumbing system through the roof vents.
Yes, a p trap under a fixture that has dried out and lost its water seal will cause sewer gas to enter your home. The source of the sewer gas can be plumbing fixtures whose traps have gone dry or have lost enough water that the water seal within the trap has broken. Water can evaporate very fast from a trap depending on the temperature and humidity in the house.
In the arid Southwest, a trap could dry out in less than a week. You'd be surprised to discover that water can rapidly evaporate from toilets and the traps below tubs, floor drains and just about any fixture within a few weeks or months in most cases. In fact, when my daughter is away at college I have to flush the toilet in her bathroom every three weeks to keep the bowl filled with water.If you are longing to get off grid, a DIY composting toilet is simple to construct and use.
I built an experimental humanure toilet and used for a year on a trial basis my bathroom is too small for two toilets! If you choose to use one, you can save a little on the utility bills, and reduce your impact on the environment.
Knowing how to make a composting toilet can open up new living possibilities such as cheap land, or your own mortgage free tiny house.
Skills such as a homemade composting toilet, handwashing your laundryor living without a fridge seem extreme to most people. A composting toilet is NOT an outhouse!
It does not smell. It does not create pollution. Building a compost toilet is a good way to take refuse and turn it into a resource. A DIY composting toilet takes human waste, and dry material such as sawdust, crushed leaves, or wood ash and composts it with straw at a high heat to kill potential pathogens.
Building a simple sawdust toilet can be as easy as balancing a toilet seat over the top of a five gallon bucket, or a gorgeous handcrafted wooden work of art. Assemble your supplies. You will need two five gallon buckets of the same height, four 2x4s the same height as the buckets, a toilet seat plus hardware, a piece of plywood larger than your toilet seat, and eight screws.My Toilet Makes Compost - No Water, No Chemicals, No Smell
Line your toilet seat up centered over the hole you just cut. Mark where to drill holes for the toilet seat hardware. Drill those holes. Place one bucket so it fits into the large hole in the plywood. Before using a bucket the first time make sure there is a few inches of cover material in the bucket. Use as you would any toilet. Instead of flushing, cover all the contents with a thick layer of cover material.
The cover material is the big key to making this system work. Sawdust is ideal, because it is fine, and absorbent. I know people have used peat moss and crushed dry leaves with good success. I had none of those things available, and had good results using wood ash from our woodburning stove.
Completely cover all contents with the cover material. When the bucket is full, put in an empty bucket and take the full bucket out to your outdoor compost bin. A three bin system works best with compost toilets. That way you have one to fill, one to cure for a year, and one to harvest finished compost. To keep your carbon and nitrogen levels balanced make sure to add lots of dry material such as straw. Use plenty of straw. If you are planning to use the finished compost on edibles make sure that it reaches an internal temperature of degrees for at least one week to destroy all potential pathogens.
For some reason, if it does not reach high temperatures it is safest to let it cure for second year. There are compost thermometers available to check temperatures. The Humanure Handbook can also be downloaded for free here.During these challenging times, we guarantee we will work tirelessly to support you.

Why is there a sewage smell in your bathroom?
To remove bathroom odors, make your own air freshener by mixing 3 parts water, 1 part rubbing alcohol, and 10 drops of essential oils in a spray bottle. Then, leave it in your bathroom and spray it to eliminate bad odors. Also, clean your toilet tank regularly using lemon juice, baking soda, and vinegar, which will neutralize bad smells coming from the toilet.
When there is a sewer smell in the bathroom, the source should be diagnosed and the fault located and repaired as soon as possible, as this is an unhygienic condition for a bathroom. The diagnosis consists of checking around the bottom of the toilet bowl for water leaks, as well as checking the connection from the toilet bowl outlet to the soil pipe. Depending on the diagnosis, it is sometimes better to have an experienced plumber affect the repair.
This is an article on how to diagnose and correct a sewer smell in bathroom, and we begin by having a look at the general arrangement toilet waste system. Regardless of the type of toilet in the bathroom, they all function on the same principle. When you flush the toilet, the toilet bowl is supplied with water from the cistern, a small tank above the toilet bowl. The water-trap is designed to withhold an amount of the newly flushed water, and this provides a water seal to prevent any smells returning to the bathroom from the main sewer.
The toilet waste outlet is connected to the soil pipe using a rubber tube, which is somewhat flexible and assists in lining up the two components. Through time the rubber can become hard and perish, allowing leakage of both water and vapors and is the main cause of the sewer smell in the bathroom. The diagnosis of the sewer smell is carried out by the examination of the following components and areas refer to the sketches below for a visual interpretation :. The surface of the floor should be dry; check for any dampness signifying a water leak from the bowl or rubber connector.
The connecting rubber tube should be gripped with both hands and shaken vigorously while attempting to rotate it, and should very difficult to move; if it moves easily it could signify a leaking joint. The above action is repeated checking along the length of the connector whilst looking for any flaws or cracks in the rubber. Occasionally a toilet bowl can crack; the seal water leaking out and allowing the smells from the main sewer to enter the bowl thence into the bathroom.
This is usually because of the ball-cock mechanism clogging up, and preventing the water entering the cistern, stopping the water seal forming in the bowl.
This is usually caused by a fault with the ball-cock mechanism and is easily fixed. Remove the cistern lid and flush the toilet. Pull the ball-cock up and down a few times, and then hold it down to ensure a flow of water is supplied to the cistern and replace the lid. If the bowl is cracked, it is better to have a qualified plumber to renew it, as floorboards may need to be strengthened and, the new toilet bowl will have to match the existing cistern piping and inlet to the bowl.
It is not difficult to diagnose and correct a sewer smell in the bathroom, provided a few simple points are taken into consideration, the main ones being to check the floor for any wet spots and all around the rubber connector from the bowl outlet to the soil pipe.
The cistern operation should also be checked to ensure sufficient water is being supplied to the bowl to affect a water seal. The rubber connector will become quite stiff with age and it is hard to check for cracks or leaks, but it is the connector that usually causes the smells to enter the bathroom. Once the leak has been found, the fitting of a new rubber connector, or adjusting the water supply to the cistern usually solves the problem of a sewer smell in the bathroom.
If the problem is a cracked toilet bowl, then the removal and fitting of a new one should be carried out by a plumber.
