Noticed a terrible smell coming from your kitchen sink recently? Want to get rid of it? We can help. There are 2 common kitchen sink smells we'll cover here:
Let's look at each of these smells and what you can do to get rid of it.
Over time, gunk can build up in your kitchen sink drain and garbage disposal. Usually, this is from putting something down the drain that you shouldn't have (such as grease, oil or fat.) To get rid of this smell, try these solutions:
These natural drain cleaners use enzymes that eat away at the food in your drain without harming your pipes. Here's just one type. We recommend avoiding harsh chemical drain cleaners like Drano and Liquid-Plumber.
This is a drain cleaner you likely already have in your pantry. Sprinkle a half cup of baking soda down the drain. Then pour 1 cup of white vinegar into the drain. Let the solution foam up and sit in the drain for a little while. Then follow it up by pouring in a fair amount of hot (not boiling) water to clear the drain.
Ice cubes in the garbage disposal can help knock food particles off the blades. Follow up the ice cubes with one of the methods above.
Running some nice-smelling citrus through the disposal can help your drain smell fresh and clean. However, if you don't also do something to get rid of what's causing the smell, it'll just come back.
Now, if you smell sewer gas, you have a different problem. This smell is leaking in from the sewer through the drain. This usually happens at one of two places: the sink trap or the plumbing vent.
If you look under your kitchen sink,home. So, if you you'll see a sink trap.
The trap is so-called because it "traps" a little water in the part shaped like a "u". That water keeps sewer gas from making its way into your home. So, if you smell sewer gas, check:
Also, if you haven't used your sink in a while (because you were on vacation or something), the water in the trap can evaporate enough to let in some sewer gas. Luckily, the fix for that is easy: just run some water down the drain.
The drain vent You could have a perfectly functioning trap and still smell sewer gas. That's because the pressure in the sewer fluctuates. High pressure can force its way through the water in the trap and low pressure can siphon out the water from the trap. That's why homes have plumbing vents. The vents allow the changes in pressure to happen without gas ending up in your home. Vents are pipes that run vertically out of your home through the roof. Each drain in your home should be connected to a drain vent.
