If your bathroom sink drain smells extremely bad and has a small clog, you may wonder if you have a serious problem on your hands. The things you use in your sink on a daily basis can eventually build up inside your drainage pipe, including the residue from your soaps and toothpastes and strands of hair. Over time, these items attract bacteria, give off bad odors, and create clogs in drainage pipes. You can try the two things below to clear up the odor and clog.
Check the P-Trap For Water
Before you do anything, you want to make sure that the problem doesn't lie in the P-trap. The P-trap is the curved portion of the sink's plumbing pipe. The trap uses water to contain debris and keep sewer odors from rising into the drain. If the trap is empty, the odor you smell could actually be coming from the sewer. You want to make sure that the trap contains water.
If you have a PVC trap, you can remove it by hand. You can remove a metal trap with a wrench. In case the trap does contain water, place a large bucket beneath it. If you see an empty trap, replace it with a new piece. The trap may be too old or worn out to function properly. If the trap is filled with water and smelly debris, you can simply clean it out. The debris may be the source of your drain's odor.
After you complete the tips above, monitor your drain for odor. If the drain still smells bad after a day or so, try the tip below.
Clean the Drain With Household Vinegar
Debris and germs can collect or build up inside the plumbing pipe connected to your sink's drain. In this case, you can clean it out with household vinegar and baking soda, which helps clear away clogs and bad odors.
Here's what you do:
- Pour 1 cup of undiluted vinegar down the drain.
- Sprinkle 1/2 cup of baking soda into the drain, then wait for it to react with the vinegar. A white foam should form inside the drain.
- Allow the mixture time to break down the gunk. Once the solution clears up the debris, the fizz should gradually go away.
You can also use a plunger to help push the debris down the pipe. However, be careful when you do so. The chemical reaction created by vinegar and baking soda can splash into your eyes. After the foam dies down, run hot water down the drain to complete the cleaning. Monitor the drain for several days to see if the odor or clog returns.
If the odor and clog does return or becomes worse, contact a plumber at a company like Moon Valley Plumbing for assistance. You may have a problem with your plumbing's ventilation system or sewer line.
