Fixing a Smelly Sink

A kitchen sink is the workhorse of the kitchen. Whether its grease, food or a plumbing issue, sinks are susceptible to smelly odors and potential health risks. Here’s a guide to help determine the problem.

Food can rot and may be the culprit of unpleasant scents. Try cleaning out your drain with hot water and dish soap. Fill up the sink about halfway with hot water and squirt some soap in. After, pull the plug while turning the disposal on as it drains. You can also pour a cup of baking soda followed by the same amount of vinegar and let it sit for 10 minutes. Boil six cups of water and pour it down the drain to help move out any residual particles. If the smell persists, you may have a plumbing issue.

A sewer smell can contain harmful gases and shouldn’t be inhaled for long periods of time. First, check the P-trap of your sink. This “p” or “u” shaped pipe can block or dry which would cause a sewage smell. There is a small cap at the lowest point of the curve which you can use to check for blockages. Clear the blockage and run the water for a few seconds to fill it back to optimal levels.Take some time to inspect the pipe for a leak and clean it out if you have to. If your P-trap isn’t the source you can have a clogged vent.

Every house has a plumbing vent. This connects your main sewer line to the outside air. If this vent is clogged, sewer gas can get into your home. If you aren’t able to clean it out easily, a professional plumber can run a smoke test to find the obstruction.
