How Do I Get Rid Of Smelly Drain?

Emergency Call - 24/7

A smelly drain is a problem that occurs in many different households with people often not knowing what to do. However, there are a variety of methods to have the bad smells gone in a short amount of time. Here at Optimised Plumbing Services, we have years working with drainage and know the best ‘at home’ methods to stop the bad smells. Fixing the stinky drain is quite easy if you know exactly the right steps to take to combat the smell.

Cleaning a smelly drain only needs a small number of materials and steps. Often solutions that combine elements of boiling water, baking soda and/or white vinegar is enough. Pouring the solution down the drain can help remove the smell, as well as cleaning it out.

Causes of Smelly Drains

There are many different components that can result in a smell drain from occurring:

When people push food down the drain, they can be stuck and the food will then decompose. As a result, bacteria can be attracted to the food which is how the smells occur.

If the pipes have mould growing within them, often as moisture builds up, tiny puff gases are released. Therefore, they will smell and can also be harmful when inhaled.

Clay joined with cement pipes, built before the 1980s, often can result in bad smells. This is because the pipes are more likely to break leading to blockages and sewage building up.

When tree roots enter pipes to then grow, it can quickly cause a blocked drain. Like before, blocked drains are overall negative, causing terrible smells to occur.

These small flies can reproduce where there is a build-up of organic matter, often in blocked drains. When many of the flies are present in the drain, terrible smells are most likely to happen.

Solutions to Smelly Drains

Fixing smelly drains can most likely be solved by using the supplies which are often already in the home. The steps are simple, while only taking a short amount of time to remove the smell from the drains.

Using Baking Soda with Vinegar

baking soda and vinegar

The most effective way to remove the smells from a drain is using baking soda and vinegar. This is because, with boiling water, baking soda will easily remove all the terrible odours. Likewise, boiling water and vinegar neutralises the smell as it contains acetic acid. Also removing other problems, like soap scum, this method is sustainable, cheap, simple and acts as a drain cleaning method. Here is how to complete this simple method:

  1. Pour almost boiling water down the drain to begin with
  2. With half a cup of baking soda, pour it down the drain, leaving it for a few minutes so the soda and water can erode the gunk and grime  
  3. Then, pour a cup of white vinegar mixed with boiling water down the drain, the chemical reaction will make sure that the remaining contents are dissolved
  4. Have a drain cover, sponge or anything else cover the drain for about five to ten minutes to let the chemical reaction happen
  5. Once the process is finished, have one more cup of boiling water poured down the drain for the last few bits of gunk
  6. If needed, the process can be repeated when the contents in the drain are not completely dissolved/ removed

Using Boiling Water and Vinegar

This method uses less materials but will most likely not be as effective as using both baking soda and vinegar. For more simple cases of smelly drains, this quicker method may be better for the situations. Follow the simple steps as listed:

  1. Pour vinegar mixed with half a pot of almost boiling water down into the drain
  2. Let the solution settle for a few minutes then have cold water poured down the drain
  3. Finish the steps by using more vinegar and hot water to flush the remaining gunk within the drain

Specifically Removing Mould

When the problem is with mould, the following steps can really help with the situation:

  1.  Make a paste from mixing baking soda with hot water
  2. Then with the paste, use a toothbrush as a tool for applying it onto the drain where there is mould. Have the paste settle there for about ten minutes
  3. With the same toothbrush, scrub the mould until it starts to disintegrate
  4. Then, have boiling water poured down into the drain
  5. After the boiling water has gone through, use a mixture of vinegar and baking soda to be then poured down the drain

Preventing Smell Drains from Occurring

There are numerous steps and actions to take for making sure the drains in your home do not smell. Here are the plumbing maintenance actions to take which we highly recommend regularly doing:

  • Clean the garbage disposal, if you have one. Placing ice cubes regularly in it can help sharpen the blades and remove any grease within the disposal 
  • Ensure that food scraps, fats and oils are not pushed/ go down into the kitchen sink but rather placed into a bin
  • Once a week pour boiling water down into the drain
  • Once a month have the solution of vinegar, baking soda and hot water poured down the drain
  • If the solution does not work, purchase stronger and targeted drain cleaning solutions or call a plumber
