Smell from kitchen sink

[elsajo]

When the washing machine in on (an draining water) my kitchen sink has a very bad egg smell. Often I can also see water coming up the plug in the sink.
I have tried bleech and the normal sink unblockers but not sure if the cause is the washing machine, the way it plumbed in or something to do the the drainage and the sink.

I had this problem.

There will be the most revolting brown gunge in the outlet attached to the side of the sink waste pipe, where the washing machine drain hose isattached.

Empty out the cupboard and line it with an old towel. Get a bucket or bowl ready to catch the filthy stuff that comes out.

Shut the kitchen door and open the windows. Prepare to gag.

Unscrew the side connector and you will find it almost blocked by an unspeakable slime. Somehow now you have to clear it out without the use of the sink.

If you're noticing a stinky sulfur or rotten egg smell coming from your kitchen sink, don't worry – it's a pretty common issue. It usually happens when bacteria and gunk build up in the pipes.

Here's what you can do to fix it:

Let Hot Water Run: Turn on the hot water and let it run down the drain for a few minutes. This can help clear out some of the yucky stuff causing the smell.

Try Baking Soda and Vinegar: Grab some baking soda and vinegar from your kitchen. Mix about half a cup of each and pour it down the drain. It'll fizz up and start cleaning out the gross stuff. Let it sit for around 15 minutes, and then rinse it all away with hot water.

Give Boiling Water a Shot: Boil up some water and carefully pour it down the drain in a few rounds. This can help break down and wash away the leftover gunk.

Say Hi to Your Garbage Disposal: If your sink has a garbage disposal, it might be part of the problem. Grab a lemon, cut it into small pieces, and toss them down the disposal while running cold water. It'll help clean and make things smell better.

Consider Drain Cleaner: If the smell is being stubborn, you could try a store-bought drain cleaner. Just be sure to read the instructions and stay safe.

Check for Clogs: If nothing seems to work, there might be a clog causing the stink. You can try using a drain snake – it's like a flexible tool to clean out the pipes. If that's not your thing, don't hesitate to call a plumber for help.

Meet the P-Trap: Under your sink, there's a curved pipe called the P-trap that traps junk and causes smells. Put a bucket under it, unscrew the pipe carefully, and clean it out. Put it back together when you're done.

Keep Things Fresh: To avoid future smells, try to pour hot water down the drain often, and once a month, use a bacteria-eating drain cleaner.

If the smell doesn't go away after trying these tricks, it might be a good idea to get in touch with a plumber. They can figure out if there's a bigger issue and sort it out for you.
