Introduction - Can bleach unclog a drain?

Homeowners commonly face frustration when attempting to unclog drains blocked by hair, soap scum, and other debris. However, one must consider whether using bleach to tackle these obstructions could cause more problems than it resolves, and crucially, if it is safe.

Unclogging a clogged shower drain can be a messy process, which is why some may be tempted to simply pour bleach down in an attempt to clear the blockage.

This article from the team at Kareela Plumbing will break down whether bleach can actually unclog drains in your bathroom at your Kareela, Sydney home. We’ll look at the potential effectiveness of bleach at dissolving buildups, as well as explore safer methods homeowners can try themselves before calling a professional plumber.

How does bleach break down clogs?

Bleach effectively cleans drains as its active component, sodium hypochlorite (incorrectly referred to as sodium hydroxide), can disintegrate organic materials such as hair, soap scum, and food particles. When bleach comes into contact with the clogging debris, it breaks the chemical bonds that essentially dissolves or “eats away” the blockage into your drain.

For minor blockages, pouring a small quantity of bleach, between half to one cup, down the drain and allowing it to rest for at least 10 minutes followed by hot water can assist in clearing the buildup.

The hot water further activates the bleach, aiding the process that disintegrates the blockages. For more tenacious clogs, consider baking soda-based solutions that provide ample time for the natural chemical reaction to work effectively.

It’s crucial not to overuse bleach as excessive chemicals can harm your drain pipe integrity. No more than two cups at a time is recommended, as excess bleach can cause damage to your pipes through repeated use. Additionally, when mixed with other products labeled as drain cleaner, bleach can lead to potentially dangerous chemical reactions.

Is pouring bleach down drains safe?

While You can use small amounts of bleach to help break down organic clogs, pouring bleach down sink on a regular basis can actually damage pipes and plumbing over time. This is because the sodium hypochlorite in bleach can eat away at the metal and seals of the pipes in your home.

It’s also important to never mix bleach with other drain cleaners or chemicals, as this can create toxic chlorine gas that is extremely dangerous if inhaled. Wearing rubber gloves and protective eyewear is highly recommended before using bleach.

For safety, it’s wiser to consider alternative techniques or call professional plumbing services before resorting to bleach for unclogging your shower drain. Baking soda, vinegar, mechanical drain snakes, or calling a professional plumber from Kareela Plumbing are often safer options that won’t put your plumbing at risk.

Risks and dangers of using bleach

Using bleach to unclog drains poses multiple risks, especially if handled improperly or in excess. In such cases, bleach can:

  • Corrode metal pipes and pipe joints over time, which can damage your plumbing system leading to leaks or bursting
  • Damage rubber seals and gaskets in plumbing
  • create toxic chlorine gas when bleach other cleaners such as ammonia-based products are combined
  • Contaminate groundwater and risk damaging the septic system if used in outdoor drains linked to the stormwater systems

The CDC reports that you can easily find many cases each year of injuries from misusing bleach and other cleaning products. Fumes from chemicals like bleach can also aggravate respiratory conditions like asthma. Proper gloves, eyewear, and ventilation are crucial when working with bleach.

For moderate sink drain blockages, a mix of baking soda and vinegar or mechanical drain snakes can safely address the issue, while enzymatic cleaners are suitable for toilet unclogging and other blockages. Otherwise, a licensed plumber has specialised equipment to clear even severe clogs in your toilet bowl without needing harsh chemicals.

Although bleach dissolves organic buildup via chemical reactions, it can, over time, cause corrosion in drainpipes and fittings. By compromising the integrity of your pipes, bleach may ultimately risk the effectiveness of your drainage system. Hence, it should not be the go-to solution for a clogged drain unless all other methods have been exhausted.

Safe ways to use bleach for unclogging

While there are risks associated with using bleach to unclog drains, when done carefully it can be an effective solution for some clogs.

If you choose to use bleach, make sure to follow these safety precautions:

  • Work in a well-ventilated area and open windows to allow fumes to dissipate
  • Wear protective gloves, eyewear, and clothing to prevent skin or eye irritation
  • Never mix bleach with chemical drain cleaner products due to potential toxic reactions
  • Use no more than one cup of bleach at a time, ensuring you carefully pour it down your sink
  • Allow the bleach to sit for 10 minutes before running boiling water over drain for at least 5 minutes to rinse the pipes thoroughly
  • After treatment, thoroughly wash any surfaces the bleach came into contact with

Repeating bleach treatments frequently can eventually corrode pipes. Consider safer enzymatic drain cleaners, mechanical removal methods like drain snakes, or calling Kareela Plumbing for professional assistance with chronic clog issues in your septic tank.

Alternatives to bleach for unclogging drains

While bleach can break down organic clogs, it carries risks like pipe damage and should not be the first solution for blocked drains. Thankfully, safer and often equally effective alternatives exist.

Mechanical Drain Cleaning

For straightforward blockages in the kitchen sink, a plunger used in conjunction with boiling water can manually dislodge the debris. Drain augers, or snakes, can hook and extract stubborn blockages, aiding in clearing the toilet and other pipes.

Baking Soda and Vinegar

Initiating a chemical reaction with baking soda and vinegar along with dish soap helps dissolve buildups like soap scum and hair from your drains. Simply use a measuring cup to portion 1⁄2 cup baking soda into the drain followed by 1 cup heated white vinegar, then flush with hot water.

Enzymatic Drain Cleaners

Enzyme-based cleaners are effective as they preserve the beneficial bacteria that naturally dissolve hair clogs. Products such as Liquid-Plumr and Drainbo gradually eliminate minor blockages.

Prevention Methods

Installing a drain cover, regularly cleaning with baking soda and vinegar, using a drain snake monthly, and calling Kareela Plumbing annually for maintenance can help prevent clogging in the first place.
