what would cause a rotten egg smell coming out of the drain of the sink and shower?

Answer 1

Try cleaning the drain, pull out the hair and other gunk from it, and pour liquid plumber into it.

Answer 2

Well, I hope you have a snake drain on the sink and shower. That would be the first thing I would inquire about, and if you don't use this particular sink and shower for a long time, water may be evaporating from the snake drains, thereby letting the gas from the septic lines flow back into the house. Just keep a replenish the drains with water once in awhile.
Good luck.

Answer 3

All the junk that goes down the drain....doesn't always go all the way down the drain. What stays in the trap gets pretty bad after a couple of days. You can use a brush type drain scrubber ( long wire rod with bristle brush on the end ) It's about 18 to 24 inches long and can easily be pushed down the drain and scrub it. I usually pour some bleach into the drain...scrub it for a couple of minutes...run clear water down for a minute...then pour another cup of bleach in drain to set there all day while I'm at work. Clean fresh drain when I get home. No more nasty smell when you are trying to brush your teeth while leaning down over the sink.

Do you have well water? Sometimes your water will smell like that due to the sulfur content of the water. If so, you may need a water softener and using rust remover pellets in the softener also helps. If you dont have well water then make sure you plunge your sink real well to start with as food may be stuck in there. Run your garbage disposal every day with plenty of COLD water (breaks up grease into chunks so it will flush away). I buy the product called Disposer Care (near dish deterg in store). It is a dry packet that is lemon scented and foams and it cleans your drain up into both sides of the sink so the foam expands into every nook and cranny. It even cleans the GD blades. Even my worst sink smells have gone away while doing these things. Make sure as part of your maintenance cleaning you wash the black splash guard protector that covers your GB on the top and bottome sides as food splatters up onto the bottom of this too. Try not to put stuff like chicken skins in there because the disposer has a hard time with this kind of texture. Also, make sure that the plug sor your sink is cleaned oftern (again top and bottom) Last, a narrow dryer type lint brush is nice to clean the non disposer side of your sink. It will let you get down there a little to clean the slime that sometimes collects. Sorry this is so long but I wanted to try to cover all bases for your source of odor. Please make sure to be safe and have it turned off before you do any work on it (nice disclaimer there Good luck to you and I hope this helps~

Answer 5

As has been indicated already, you probably don't have a 'snake' pipe or 'U bend' on the drain system. Look there first and if there is one pour water down the drain to ensure a good water seal

Answer 6

Don't use drain cleaner. Just clean your shower and sink regularly with tub and tile cleaner, and this will rid the problem. Also a 1/4 cup of bleach will help. But of course don't mix your chemicals.

Answer 7

it could be sewer gas smell, pour some water down the drains

you could also try cleaning the drains, you could hook a coat hanger to pull any hair or debris from the drain

Answer 8

Sewer gas. One of your vent pipes may be clogged with a dead bird or small animal.
