Check where it connects under the sink to the drainage or the garburator. It will more than likely be plugged somewhere near that connection. Unplug it, and run 2 cups of vinegar and 1/2 a cup of baking soda through a long hot cycle in the D/W. This should get rid of the sewer odor.

Where can the sewer gas smell come from if it does not come from the drain of the ower- level on-a-slab shower?
Answer One of the biggest culprits I have found for sewer gas smell is the floor drain many floor drains are seldom if ever used and if unused long enough the wa…ter in the trap will evaporate allowing sewer gas to enter the dwelling. this also applies to any trap which is not used regularly.
Answer Code there doesn't always require a 'P' trap to hold water and thus block sewer gases from backing into the house.
Answer Your traps could be being siphoned from improper venting, an "S" trap on one of your fixtures, or a cracked trap below slab level. It could also be t…he wax seal around your toilets. It is difficult to say without seeing your house.
Answer Without knowing more of your situation, let me speculate: The draining of the washer happens quickly. The draining water causes a vacuum in the …line which then sucks the water out of the trap(s) in the other fixtures. This lack of water seal allows sewer gas to enter the house. This could be caused by an improperly installed fixture, one perhaps installed by a homeowner or Mr. FixIt that did not appreciate the necessity for properly venting a fixture. A quick fix might be a Studor Vent. These are not approved in all locations-check your codes.
Answer 1 I suspect that you have a "p" trap in either a floor drain, or possible the laundry tub or a sink somewhere in the house. If you look under the kitc…hen sink, or a lavatory in the bathroom you can see a p-trap, it's shaped sort of like the curved part of the letter p. The purpose of the p-trap is to trap, or prevent, sewer gasses in the sewer lines from backing up into the house. By design, p-traps catch and hold some water, which blocks the pipe and stops the gas from coming up through the drain. IF you have a floor drain, or a lavatory drain, either of which don't get used enough to keep the water in the trap from evaporating away, leaving the drain pipe open, then when a lot of water is poured or flushed, pumped out of a washer, then that flowing water will push sewer gasses back up through the drain with the dry p-trap. What you are smelling is sewer gas.
Filter is plugged, or you need anew pump.
Mine doesn't smell at all, but then again I make sure all trap seals are replenished.
Have the lines water Jetted to scour them properly and get rid of years of crud build up
because if we are not provide u trap in drain line other wise battle value inside the trap
Heck no as it is a very carcinogenic mixture
no, unless there is something being put in a drain nearby that has a lot of chlorine in it such as pool water. Sewer gas generally smells like an out house.
A drain flowing into a sewer either combination or sanitary or storm depending on what type of drain is being used such as storm drains or waste and this does not include Soil… lines
Floor drains that do not have water flow through them will go dry and sewer gas will leak out of them because the trap makes a seal and stops air from flowing out of the floor… drain. Most commercial properties have drip primers that allow water to drip into a floor drain and keep the trap sealed but because water is dirty and since the drip primer has to have such a tiny hole, over time the drip primer corrodes and stops working and stops keeping water filled in the trap which is below any floor drain. When this happens like 2 - 4 yrs after the building was constructed the owner (like most) don't care or even know to care where the drip primer is. The best way I believe to seal a floor drain trap that is hardly used is to pour 1 gallon of water then 1/2 cup of vegetable oil down the floor drain, this oil sits on top of the water constantly making a seal on top of the water so the water can not evaporate and always making a trap seal.
No. It has a very specific odor because natural gas really has no odor at all so Mercaptin is added to give it an odor unlike anything else.
yes. water caught in the drain line may contain food particulate which can decompose and cause gasses to escape back into the house.
