"F. Phillips hit the nail on the head! If you're in Maine, it's November, it's cold, the vent pipes for the plumbing sometimes get clogged with ice from condensation. If it's been cold & dry, the water in the sinks, tub & washer vapor traps evaporates a little quicker than normal. You may also notice the pipes & drains making an unusual noise when one of the vapor traps dries out. Pouring water into all drains will reestablish the "vapor trap" & the smell will stop entering the living spaces.

Check the vent pipes on your roof. They could be plugged. If they are plugged, odor will come out the drain or toilet.

My friend told me that a mixture of vinegar and baking soda works as good as Drain-O, and it takes the odor away. I haven't tried it myself, but it's worth a try.

What would cause a sewer odor coming up from my drains? I live in the city and do not have a septic tank. I occasionally get the same odor from my washer. I assume its from the pipes because my laundry doesn't smell, just the entire room. Thank you.

RE: Sewer Odor Coming From Drains

Usually odor comes from dry traps in plumbing that have not been used for a while, and can be remedied by pouring water into the drains. However it sounds like you may have a broken or rusted drain pipe beyond the drain allowing gas to come out. Take a good look at your drain plumbing and perhaps where the clean out cover is, it may have come loose. Good luck and God bless. (09/10/2008)

I'm not sure what causes it, but I think I've had the same problem from time to time. Running hot water full force for 10 minutes or so from all available faucets usually takes care of it. (09/10/2008)

I used to get the sour water smell coming up our drains also. What I found that works is when ever you are boiling large amounts of water (for corn, pasta,etc), instead of dumping it down the kitchen sink, dump it down the sink that smells. Once is usually enough but sometimes another time or two is required. I got into the habit of rotating the sinks whenever we boiled water and we have no smells coming up. It also helps to get rid of the hair that collects. Be careful carrying the boiling water especially if you have small kids. Good Luck! (09/10/2008)

I had the same problem in my laundry room. My husband had put my drain hose for the washing machine up too high and therefore when the water pumps out, it pumps it all out and the trap is dry of water and causes the smell. A friend told us that the drain hose can only be 8 inches above the trap. We fixed that and the smell is gone. (09/11/2008)

I live in an old house and have the same problem. The kitchen is far from the sewer pipe which is vented. A smaller vent is needed from the kitchen pipe. (09/13/2008)
