Answer 1 First it is necessary that you understand the source and cause(s). Sewage smell is caused by decomposition of sewage throughout the entire system, including the sewer mains. Any opening in the sewer system will allow vapors to escape. As a matter of fact, the plumbing system vents sticking up above your roof are there to vent any such gasses at a height which is considered to be far enough away from human activity to not interact with people. If you were to remove a toilet, a lavatory, or sink from the drain system, leaving an open pipe end, those sewer gasses would enter your home. Even with those fixtures in place, still gas could enter through the drain opening, EXCEPT that codes require ALL DRAINS [including floor drains buried in a concrete floor slab] to have what is called a "P" trap installed at the drain outlet of those devices. The p-trap is so named because it resembles the letter "p" lying on it's side such that the curved part is downward, creating a "u" shaped loop which will catch and hold [trap] the last bit of water draining through it. In effect, this creates a "plug" of liquid in the drainpipe, which prevents the sewer gasses from backing up through the fixture drain into the house. Now, with this knowledge, we can approach the question of how intermittant odors occur, assuming there are properly installed p-traps in all drains in the house. IF there is not a p-trap, or it's not properly installed with the curved loop down, so as to trap water, then the fix is to reinstall it properly. However, since you use the term "intermittantly," suggests that there are properly installed p-traps and there must be another cause. Occasionally, where you have plumbing fixtures that are seldom used, the plug of water filling the p-trap will evaporate, leaving the p-trap open thus allowing the sewer gasses to enter the house. Each time water is run through a drain, the last of the flow refills the p-trap. I suggest that for any fixture drain which is not used at least monthly, you intentionally run water through the fixture every two weeks. This should preclude evaporation of the plug, and prevent entry of sewer gasses. There is one other possibility of sewer gas passing through a fixture drain, even IF the p-trap is properly filled with liquid. If the roof sewer vent pipe is blocked or restricted [by for example, like a bird nest at the opening, or a blockage due to accumulation of spider webs and trapped tree leaves in the vent], then when a toilet is flushed, or a bathtub full of water is drained, then the quick, heavy flow of water into the sewer pipe system displaces the atmosphere [air and sewer gasses] in the system faster than the restricted vent system can handle. In this situation, it is possible that the pressure build up of sewer gasses, exeeds the strength of the p-trap water plugs to resist. Then the sewer gasses will bubble up through the p-trap water plug into the house. Another thing which can cause the same backup through the liquid filled p-traps are large, but incomplete restrictions [partial clogs] downstream in the sewer pipes. Thus, you stop intermittant sewage odors inside a house by finding, and correcting the defect which allows the sewer gas to escape the sewer system.

Thanks for the feedback!
Bad venting system and possibly an untrapped, or dry trap on the shower's drain. Does this envolve a bathroom addition? Answer sound…s like something is improperly vented...or your traps siphone due to improper distance between the elbow and downpipe
What could be causing your kitchen sink drain to stink like sewage occasionally while all other sink drains are fine?
The drainpipe under the sink should have a "U" shaped bend called a P-trap. Its purpose is to always hold a small amount of water in it which will block sewer gases from comin…g up through the sink and into the living space. The problem could be: No P-trap at all, which is unlikely. P-trap water has evaporated from prolonged lack of use, unlikely in most homes. The P-trap leaks, which may permit sewer gas escape. The P-trap is dirty and needs to be removed and cleaned. P-traps are not maintainence free. It would be a good idea to remove and clean them after years of use, and you don't need a plumber to do this if you are reasonably handy. And in the meantime, occasionally pour a little bleach in your sinks before you go to bed. ANS 2 - Remove the P trap and clean it and the pipe above it thoroughly. If necessary fit a new P trap.
What could be making the terrible smell under the house which is not a dead animal not sewage but a sulfur like strong onerwhelming dirt smell?
Answer It is probably a dead shark. I had this problem so i went under my house and found a rotting bees nest. If you have ever been to hanmer springs …in new zealand, there are hot springs there which have a strong sulphuric smell. There are also thousands of bees there. While the bees do not cause the smell, they certainly make it worse. Look for any traces of bees under and around your house and spray contaminated area/s with water and sodium bicarbonate, which will neutralise the smell.
It could possibly be coming from the drain. There is water in the drain that goes to your septic or holding tank even city sewer that stays in the pipe acting as a plug …to prevent the odor from coming up. Same as an elbow on a sink drain. If that water evaporated or somehow drained, then your drain now has a direct contact to the sewer/septic. Imagin it being like a snorkle connecting the sewer gas to your basement. If this is your problem the fix is easy. Simply pull the floor drain cap up, usually two or three screws. Pull out any debris that may have gotten down in there. Pour a few gallons of water down the drain. You should see water in the drain at all times, but still pour a few gallons down. Your creating a plug between your basement and the sewer. After this is done, vent the room with fans. Wait a few hours and see if the smell is gone. If it's still there you may have a bigger problem. Call a plumber who can narrow down the causes in just a few minutes. ALSO, maybe just check around with a flash light, you might find the source of the smell is simply a dead mouse!
wax ring gone, or possibly vent stack broke.
Poor venting / Wax seal needs to be replaced
All You Have To Do Is Better Some More Drains You Cheap Gayer Go And Have A Bath
Sink drains smell because there are particles in the sink trap decomposing. To prevent such smells in a kitchen sink drain, try not to allow food to go down the drain at all,… making sure that the sink plug fits properly and is emptied into the trash after each use. If food does go down the drain, be sure to flush well with water to propel any particles past the sink trap (U junction under the sink). If you have a garbage disposal attached to your sink, be sure to run water with the disposal even after it appears the material is ground up, and continue to run the water for a minute after you turn off the disposal unit, to flush any remaining small particles. Bathroom sink and tub drains smell because they have hair and soap residue suck in them. These build up over time, eventually leading to slow draining and complete clogs. To avoid this be sure there is a catch over the drain to block hairs from going down the drain and empty when there is any matter in it. Do not flush fallen hairs down the sink, but rather get in the habit of putting them in the trash, wiping them up with a tissue if needed. If your drain already smells, try the easiest fixes first: # Run hot water through the drain to try to flush away any particles. # Pour some of vinegar (a very mild acid) down the drain to loosen soap scum and grease, as well as freshen. If this is a kitchen sink with a garbage disposal, try grinding up a lemon or orange (provides citric acid, and a mre appealing smell.) # If drain is slow, try removing any clumps stuck in drain-- a straightened coat hanger works well for hair clogs. # Try more vinegar, this time with a small amount of baking soda. Warning: Use only enough baking soda to fizz slightly in the vinegar. Pouring too much can cause a large-scale reaction which can damage pipes. Remember those science fair volcanos? # Use a chemical drain cleaner such as Drano or Liquid Plumr. Follow package directions. Leaving the product in the pipes for long periods can corrode pipes, so try a shorter period of time first, and always be sure to thoroughly flush the pipes with hot water afterward. Do not mix these chemicals. Do not use bleach.
Yes, a sewage drain pipe can be too large.
Sewage smells like sewage it stinks Answer: At the sewage plant sewage has a wet heavy odour like animal waste it i not entirly unpleasant and is easily acclimatized to, T…exts refer to this aroma as earthy, farmlike or even goatish.
see that vent is downstream from trap
For basin drains shower and kitchens use a cheap bleach. It is effective, cleans everything, and smells hygienic. Regular cleaning is the key. Also, take the plug apart and cl…ean the inside. A lot of hair, dust and stuff gathers over time. A real good clean out will do a lot.
All drains stopped up after inadvertently flushing large glass chunks from Shop-Vac down one toilet Now all drains in house are backing-up What is the best remedy?
Open up the main drain (inspection cover in the driveway) and remove the blockage manually.
Like poop, pea and nastiness. I can't really explain it. It just smells REALLY bad. Yah can't really argue..... Just imagine all the nasty stuff that goes down your toilet tha…t's mixed with dirty water and mud and has been sitting for 2 months.... Yupp tastes good doesn't it
Assuming there is a trap under the drain, just pour at least a quart of water down the drain. this will fill the trap and block the flow of sewer gases into the building. A t…rap is the U shaped drain pipe that you see under you kitchen and bathroom sinks. Water going down the drain gets "trapped" in this U shaped pipe and blocks sewer gas from flowing back in to the house. If a drain is used infrequently, the water will evaporate and allow sewer gas back into the house. In this case, you may have to add water monthly to ensure that the water has not evaporated. If this does not work, it means there is no trap present. You will either have to add a trap if you can access the pipes or simply cover or plug up the drain.
There is a blockage.
