Is It Safe To Pour Bleach Down Your Home's Drains?

Believe it or not, but one of the most common Googled questions is “Can you put bleach down the drain?” But why do people even pour bleach in their drains in the first place? Well, they do it for a multitude of reasons: either for odour removal, disinfecting, or because their drains are clogged.

Now, while bleach is a powerful disinfectant, it might not be ideal for plumbing systems. There are a multitude of reasons why that is the case, which is exactly what we’re going to discuss in this article. We will cover effects, risks, and other safer alternatives to pouring bleach in drains.

Can You Put Bleach Down the Drain? 

A lot of people believe that they can just pour something down their drains and it will disappear, but that’s really not the case. People pour bleach down sinks, showers, and toilets for mainly two reasons: one is disinfecting, and the other is unclogging. Disinfecting is when there is a lot of bacterial overgrowth, which causes a foul smell, so you just pour bleach down the drain to get rid of it. On the other hand, while unclogging, something is blocking the drain, and it needs to be removed. 

Before you ask, “Can you put bleach down the drain?”, you need to first understand what type of plumbing system you have: do you have a municipal sewer, or do you have a septic system? If you have the latter, then do not pour bleach down your drain under any circumstances. A small, diluted amount may be acceptable in municipal sewer systems.

What Happens When Bleach Enters Your Plumbing?

What exactly happens when you pour bleach down your drain? There are some other things that do happen inside the drain in its system, which are not exactly ideal.

Chemical Reaction Inside Pipes

Sodium hypochlorite is the chemical name for bleach, and it is highly alkaline in nature. It can react with any form of organic matter, grease, hair, soap scum, and it will create harmful fumes if you mix it with other cleaners, especially those that are ammonia-based or acid-based.

Impact on Pipe Materials

Most homes use either PVC or metal pipes. Older cast iron plumbing can be severely corroded by bleach, and even if you think, “Oh, I have PVC pipes and they’re safe for bleach,” you could not be further from the truth, as most PVC pipes have rubber seals and fittings in them, which may degrade over time, and the degradation will be accelerated thanks to the bleach.

Effect on Drain Buildup

If you think bleach is great for unclogging drains, think again, as while bleach is a good disinfectant, it does not dissolve grease or any other solid blockages effectively, though it might temporarily reduce the odours, but it does not address the root cause; it’s kind of like applying a bandaid over a fractured bone.

Can Bleach Unclog a Drain?

That’s what brings us to the main question: can bleach unclog a drain? The answer is no. Bleach is not designed to break down hair or other solid clogs. It does work on odour-causing bacteria, which might give you some relief from the foul odour, but it will not unclog your drain from any kind of physical obstruction. It may appear to work temporarily because you’re losing the bad smell, but if the clog is too severe, it might just need mechanical removal instead.

Risks to Pipes, Septic Systems, and Beneficial Bacteria

So what risks does bleach pose to pipe materials, septic systems, and beneficial bacteria?

Situations Where Limited Bleach Use May Be Acceptable

Now, this does not mean that you cannot use a little bleach here and there; as there are certain situations where you can use a limited amount of bleach, for example, you can dilute the bleach and just flush it down for some occasional disinfection, you can pour bleach down the drain and then later flush it with plenty of water after that, if you’ve had sewage backup recently, then you can use bleach to sanitize after contamination, though make sure you avoid frequent or concentrated use and do not mix it with any other drain cleaners as that can also cause unforeseen chemical reactions.

Safer Alternatives for Cleaning and Odour Control

So, are there any safe alternatives?

Conclusion

Only in some aspects is bleach helpful, and it’s not an effective solution for clogs. If you’re looking for something that can unclog your drain, check out Dr Pooper’s Drain Field Cleaner. It increases the amount of beneficial bacteria in the septic tank, which naturally unclogs the septic system.
