How to get rid of sink drain smell?

Question

Our sink drain smells really bad. we've tried everything, bleach, hot water, drain unclogger, someone even told us to pur coca cola down there and then more hot water and nothing helps.

are we just doomed to a stinky sink?

thanks for your suggestions!

Answer 1

It may not be that your sink itself is stinky, it could be that your septic system is venting back out. Does your sink have a "p"  trap? its a curled peice of pipe connecting your plumbing to the drain. If this is missing then you deffinatly found your problem. If this is not it, it may help to pour javex as it kills bacteria. Try using a brush and cleaning your drain up untilthe "p" trap.

Good Luck  

Answer 2

If vinegar and baking soda doesn't work try pouring bleach into the drain, let stand for a few minutes then flush with hot water.

If this still does not solve problem remove trap on sink drain and clean also check the vent pipe coming out of roof for obstructions.

Answer 3

You don't mention if you have a garbage disposal or not. If you do, put any kind of citrus peels down it and grind away, orange, lemon, lime, all will make it smell great. Baking soda is another great odor eliminator. If none of this works, you may have a more serious problem, you may have a leak somewhere that is allowing gases to back up into the house and may have nothing at all to do with the sink drain. If you have a septic system this can easily happen. also if you have a roof vent it could be clogged.  

Answer 4

Baking soda and vinegar.

Answer 5

drain snake

Answer 6

baking soda , vinegar , I usually pour a bit of pure bleach down the drains when I'm done cleaning the sink or any drainage that is around the house .

Answer 7

I use Lemon in my ice tea and put the left over portion down the disposal every night. The citric acid seems to keep any odors away as well as keeping the gunk from building up in the drain.  

Answer 8

eep. you might want to get down under the sink and take the pipes out and clean them. Or hire a plumber.

Try Tray's idea first tho, it's a good one

Answer 9

I use bleach or vinegar  and it works or me.

Answer 10

Couple of methods I've used.

i use a cup of baking soda leave it for min 1/2 hour then chase it down with a kettle of boiling water.   I've pored a cup or so of laundry detergent down the drain let it sit for a while and chased that down with boiling water.  

Answer 11

most of the people here say the same thing.  here's my take.

i agree with Don B.  it's possible that a soft stoppage is occurring in your pipes.  i recommend snaking the pipe with lots of water running to disturb the debris and rinse it through.  

once the pipes are "reamed" of debris, the smell will naturally be gone.

Answer 12

baking soda and vinegar, let it sit without using water through the sink for  good couple of hours,  if that fails get hubby/bf? to unscrew the pipes under the sink and see if theres anything sitting in there, if not a good clean of the pipes and a soak in disenfectant cant do any harm, and if that fails?.. well a plumber maybe perhaps he could check that everything is flowing alright and flush someting through the house water works.  Good luck

Answer 13

What Tray said.  Baking soda and vinegar.

Answer 14

COPIOUS amounts of water (cold - hot water will make it more "aromatic" as it's being rinsed) and baking soda. I'd let the baking soda sit at least overnight (longer, if possible) before flushing the drain with water.
