Unblock a Drain Using Caustic Soda


Introduction Although fairly common, a blocked drain is enough to drive most people to their wit’s end. An obvious recourse in such cases is to call on the plumber and while that’s a sensible option, there are certain things that you can do yourself to unblock a drain.   The vast majority of  blocked drains  are caused by jammed up debris like hair, food particles and other unwanted materials. Natural drain cleaners are often ineffective at removing this debris completely, which means chemical-based cleaners are your best option. Here we look at one such cleaning agent, caustic soda, and how to use it to unblock drains in your house


What is caustic soda? The chemical name of caustic soda is sodium hydroxide ( NaOH ) and it’s also known as lye. The name caustic soda is derived from the material’s origins as a sodium hydrate and it’s called caustic because, well, it’s highly corrosive in nature . It’s the last bit that is of most interest when we talk of unclogging  blocked drains .


How to use caustic soda for cleaning & unclogging drains? Take a large bucket and dilute 3 cups (750 ml) of caustic soda in 3 litres of cold water. Use a wooden spoon or stirrer to mix the soda and the water. Do not use these containers and utensils for any cooking-related purpose later on. Also, avoid using your hands to stir the mixture. As you mix up the two, you should see a bit of fizz and some amount of heat. Now pour this solution straight drown the blocked drain and let it sit undisturbed for 30 minutes. Now boil 4 litres of water and use it to flush the drain. If the block persists, you can repeat this procedure a couple of times.


Considerations when using caustic soda Although highly effective, using caustic soda to clear  blocked drains  is not without its share of challenges. The biggest risk it poses is to your health and safety. Caustic soda’s corrosive nature, while a boon when trying to get rid of difficult blockages, can lead to vision impairment. At the very least, direct contact can create a burning sensation and swelling in the eyes and the skin. The consequences of ingesting it are far more serious. From chemical burns to gastrointestinal ulceration and even death, caustic soda’s effects on health can be devastating. If you have decided to use caustic soda to clear a blocked drain, do so after wearing full protective equipment. When you are done using the caustic soda, secure it properly and store it out of the reach of children.
