Why The Sink Drain Smells BadA properly maintained residential septic tank should never smell. That means a bad odor inside the home or near the leach field is not a good sign. Smelly septic tanks are a result of the presence of gasses in the system, including hydrogen sulfide, carbon dioxide and methane. The pH levels in these gasses are too acidic for the microorganisms in the tank to digest the organic matter, causing the tank to smell. Not only are these odors unpleasant, but a high concentration of a combination of these gasses can be explosive or even toxic. If you are smelling this oder, it needs to be addressed ASAP. Luckily, septic tank odors may be remedied relatively easily using a few common household products.

Clean The sink Overflow

If your bathroom sink is smelly, check the sink overflow. This hole is usually located either underneath the faucet or directly across from it. Often, this overflow can become clogged, allowing odors to enter your bathroom. Use a small bottle brush, or mix a solution of half bleach, half water to clean away the buildup.

Clean The Sink And Tub Drains

Bathroom drains are inundated with many different types of materials. Hair shampoos and conditioners, toothpaste and soaps can all clog drains. This buildup can lead to bacterial growth that can cause odors. One easy do-it-yourself solution is to use vinegar and baking soda to clear away the buildup. The vinegar and baking soda will react, causing it to bubble. You can repeat this process until the smell disappears. Use this trick as part of your regular cleaning routine to keep your pipes clean and odor-free.

Check For Leaks

It is possible that sink drain odors could be originating from leaky pipes. If a pipe is leaking, sewer smells can escape into your bathroom. Check under the sink for any signs of a leak, such as standing water or evidence of a water ring.

Clogged Vent Stacks Or Drain Lines Leading To The Septic Tank

Sometimes pipes and vent stacks become clogged, causing sewage gasses to back up into the house. As a rule of thumb, it is suggested that the tank be pumped every two to five years to remain functioning properly and prevent system failures.
