Every time I turn on my bathroom sink, it stinks like rotten eggs! (strong sewer smell). This does not happen anywhere else in the house. The kitchen sink, tub/shower, and washing machine do not stink at all, but the bathroom sink is just horrible when you turn on the water. Does anyone have any ideas why this would be and what to do about it? Thanks!

First I'd check the drain trap... the 'J' shaped curve in the drain pipe under the sink. Make sure it isn't leaking. Then sniff around to be sure the odor is coming from the sink itself and not perhaps from the bathtub drain, behind a wall, etc. If it is certain that it's coming from the sink itself you could have something unpleasant growing in the overflow drain in the sink. If that seems likely I would try the following, but only if I was certain no ammonia could be lurking in there: I'd pour some clorine bleach through the overflow system from the highest point accessable. For instance my sink has an indentation to hold a bar of soap and there is a small drain hole there. If you can get the bleach to it this should kill anything that might be making a home in there.
Be sure there is no ammonia present though, before you add bleach. If the two are mixed together the fumes are highly toxic. Good luck!
All the above answers could be correct.
If it is a build up of gunk in the trap ("S" bend) then there is a products in Australia that I have used and found very useful (but you must follow the directions very carefully). The product I have used is called "Draino" which is very strongly alkaline. It should kill any germs as well as clearing and obstruction.
Another possible consideration is if the plumbing has been modified or not installed correctly, you may not have a trap ( S Bend), if this is the case the smells from the main sewer pipes will be coming directly up into your sink. This is unlikely but I have seen this in a Do It Yourself (DIY) installation once. If you are not sure if you have the correct trap get some one in to check; no drain should be connected with straight pipe directly to the sewer pipes there must be a loop of pipe which holds some water to prevent the smells from passing up the pipe.
Check the vent pipes coming out of your roof. I started getting this very unpleasant smell in my back bathroom and could not get rid of it, same odor, smelled like rotten eggs. I took barbed wire and twisted it at the end to form a small 'ball' and went on the roof and worked it down the vent pipe. I thought maybe something, a small bird or small squirrel might have gotten down that pipe somehow. I know, this was a long shot, I really couldn't see how anything could have fell in and gotten stuck, but I tried this anyway. I just kept working the wire down the vent. At one point, it balked, like it was blocked.
So, I had to just make jabbing motions with it and all of a sudden, it started going again. When I felt that I had used enough wire to remove any object that might be blocking the vent I stopped, climbed back off the roof and went inside to check the bathroom. The odor was gone! I was one happy camper! I then went back on the roof and pulled the wire out. I was going to get some fine mesh wire and make 'covers' for all my vents, but never got around to it. I haven't had this problem since however. I'm sure there are better objects to use instead of barbed wire. I would have used a snake (plumber's snake) if I had had one, but I didn't, so I used what I had at hand. I still don't know what was blocking that vent, but it got it pushed on down to where it went out into the septic tank and I was rid of the odor and very happy about it.
Thanks to this site i fixed the problem myself.
Here were my symptoms:
1. Newer house
2. Smell of sulphur was in 1 room (bathroom)
3. Isolated the smell to the bathroom sink
4. Toilet / shower were fine
Removed trap under the sink (no tools required because of the PVC) and got rid of all the build up (mostly my wife's hair). Smell has dissappeared.
We just moved into a new house our problem is the smell of our water and drains. It smells like rotten eggs. The washer is gross too, every time I wash clothes they either smell like rotten eggs while washing or the machine does. It is very gross. Taking a shower is also smelly. We don't have hard water and tried that with dish soap and water. Please help.

Congratulations, you have sulphur in your water. I know this becasue I've had to deal with it in a house we purchased some years back. You have to aerate the water to remove the smell. We did this by going to the pump house and installing an aerator. We got this from a water testing company. Call or go by a place like that and ask. They'll tell you.
Sounds like well water to me. Our water smelled horrible when we moved in less than a month ago. Once you get the water cycling through the house (I think it took my husband and my use for about a week). It will clear up to almost nothing. Hot water is the worst. We ran the tub and the sink for a couple hours the first couple of days. Now, we also have our well chlorinated once a week. Good luck!
I purchased a house back in April 2013 and at the time I purchased a new filter and softener system for the house as the water had a strong rotten egg smell. A year later I had the issue with the hot water (rotten smell in hot water), and I resolved it by changing the anode rod every 6 months. Now two weeks ago I started getting the rotten egg smell in cold water only. I called the company that installed the systems and they did all the chemical tests in water and everything resulted in normal readings. So they recommended line chlorination because they said there might be bacteria growing in plumbing and it might be producing that rotten egg smell. Therefore, we agreed to try; but unfortunately 3 days after the chlorination the smell came back, but it came back even stronger. and again only the cold water. Then the next two days the water was fine without any smell and then it started all of a sudden. (Basically the smell comes and goes.) The strange thing is that I always go check outside to see if the water right after filter also stinks like rotten eggs, but it doesn't. The smell is only inside the house, on showers and sinks.
Thank you very much in advance.
We recently had a new well driven and the water smells like eggs. Does anyone know what is causing this and if it's OK to drink?
Here's some information I found on an extension site...
Why Well Water Smells Bad
If you have a private well and the water smells musty or like "rotten eggs," you may have a bacteria problem. Bacteria that cause this smell live in the soil or aquifer. They are not a health risk. However, once introduced to a well, they may multiply rapidly and cause odor problems.
Sometimes odor-producing bacteria indicate that disease-causing bacteria are also present. This is especially true if there has been a sudden change in water quality. Have your well water tested through a certified lab to make sure there is not a health problem. Tests usually identify potential health problems but may not detect odor-causing bacteria. The lab lets you know if water is safe to drink. If it is safe but smells bad, you can reduce or eliminate the odor.
Odor-producing bacteria are often referred to as "iron" or "sulfur-reducing" bacteria. They use iron or sulfur in their life cycle and give off hydrogen sulfide gas. That's the rotten egg odor. The bacteria may form slimy colonies in pipes or toilet tanks and can stain laundry. However, the odor is usually the most objectionable problem.
Iron bacteria can get into wells when maintenance is done on piping, well casing, or pumps. Bacteria can get in when work is done on indoor plumbing, or when a hot water heater is installed. Finally, they may get into water supplies through a direct connection to surface water or shallow groundwater seepage.
Once established in your well or water supply, bacteria can be very hard to eliminate. After work is done on your well or plumbing, thoroughly disinfect the system. This kills bacteria that enter the water before they get a foothold. If there is a connection to surface water or bacteria are strongly established, repeated disinfection may be necessary. Disinfection eliminates or reduces bacteria to tolerable levels.
Shock chlorination is the most common way to disinfect a well. You need to calculate carefully how much chlorine is appropriate for your well size and depth. Make sure the entire system gets disinfected and that chlorine remains in the system 6 to 8 hours.
Sometimes rotten egg odor comes from rock the well is drilled into. In these cases, the smell is generally present when the well is first used. The smell may decrease over time. Odor that appears later is from bacterial growth and may appear suddenly. The odor may begin after the well has been unused for an extended period of time, following floods or drought, or after maintenance. Again, a sudden change in water quality may signal potential health risks. Test the water to make sure it's safe to drink. To get a water test kit, contact your county health department.
