Why Does My Kitchen Sink Smell

There are a few reasons why your kitchen sink may begin to smell worse than old aunt rose.

Food Buildup

Food In P-TrapThe most common cause of odors coming from the sink is food. Every time we wash our dishes, we wash oils, fats, sauces, and food particles down the drain. We think nothing of it; out of sight, out of mind. Well, that’s true until it all comes back with a foul vengeance. As more and more food is washed down the drain, there’s a higher chance that food will build up, especially if you use a garbage disposal. As food builds up, it begins to decompose and release the disgusting odor that you are very much familiar with.

P-Trap Problems

If you take a look underneath your sink, you’ll see your P-Trap. It’s the curved piece of pipe connected to your sink drain. This pipe is why you don’t normally get a smell coming from your sink. Whenever you run water down the drain of your sink, water drains down through that curved piece (the p-trap). When the water stops running, there will still be some water in the p-trap pipe. This is exactly what is supposed to happen. When water sits in the curve of the p-trap, it creates a water seal. No smells past that can come back up through your drain because the water prevents air from escaping.

There are a couple of issues that can cause your P-Trap to allow air and odors back up through the sink drain:

1.) You Don’t Have a P-Trap. It is terrible to say, but sometimes DIY’ers don’t actually know what they’re doing. Every sink MUST have a P-Trap. That’s plumbing code. If you don’t have one, you’re going to want to call a professional, licensed plumber to make sure the job is done properly.

2.)Your P-Trap is Leaking. It is definitely possible that you have a leak coming from your P-Trap. The leak may be caused simply by a loose connection. Or it may be leaking from the pipe itself. The integrity of the P-Trap may be compromised if you use Drano or Liquid Plumber, which can soften and weaken pipes.

3.)Changes in Pressure in Your Plumbing System. When you have changes in the pressure within your plumbing system, it can cause the water in your P-Trap to move and fluctuate. When the water moves, the water seal may be broken and air may be allowed to exit through the drain.

4.)You Haven’t Used the Sink in a While. If you’ve been away from home for a while or if you just haven’t run water through your sink in a while, the water in your P-Trap may have evaporated. This is an easy fix. Simply turn the sink on and run some water.

Alright! So by now, we should have a good idea of why our kitchen sink smells. Now let work on making your kitchen sink smell better!

Ways to Get Rid Of Smell From Food Buildup in Your Sink

1.) If You Have a Garbage Disposal, Use Ice. Putting ice in your garbage disposal and turning it on will help knock away any food that’s been overstaying it’s welcome

2.) Vinegar and Baking Soda. Pour 1 cup of vinegar and 1 cup of baking soda down the disposal and let it sit for about 5 minutes. And then pour hot water down the drain to wash it out.

3.)Enzyme Drain Cleaner. Enzyme drain cleaners can help rid your pipes of food buildup. The enzymes in these drain cleaners will work to break down the food to wash away the source of the foul odors while also working to prevent future buildup.

Ways to Fix Your P-Trap1.)Inspect The Connections. If the connections on your P-Trap are not properly tightened, water may be escaping and the water seal may not be effective. Tighten any connections you found that were loose, then let the water run so that you can reform the water seal in your P-Trap.

2.)Have A Plumber Inspect The P-Trap. This is going to be most people’s last resort, but it will always be the most effective. Plumbers are able to diagnose whether the problem is with the P-Trap itself, or if there is an issue with your plumbing vents that is causing changes in pressure within your plumbing system.
