drain cleaners

Homeowners facing stubborn clogs or slow-draining sinks typically turn to drain cleaners as a solution. Enzyme drain cleaners and chemical drain cleaners are two popular choices in the market; each offers unique advantages and disadvantages, so knowing when and how best to utilize one over the other could make all the difference in solving your plumbing issues effectively.

In this comprehensive guide, we’ll explore the differences between enzyme and chemical drain cleaners, delve into safety considerations for septic systems, and evaluate situations where they might fall short in addressing plumbing challenges. If you’re in Edwardsville and seeking professional assistance, don’t forget to check out our drain cleaning services.

Understanding Enzyme Drain Cleaners

Enzyme drain cleaners offer an eco-friendly and natural solution to maintaining and clearing away clogs in your plumbing system. By employing enzymes and bacteria to break down organic matter such as food particles, grease buildup or soap scum that accumulates within pipes, enzyme drain cleaners help combat blockages by dissolving organic materials like food particles, grease or soap scum buildup. 

Below are the key characteristics of enzyme drain cleaners:


A key advantage of enzyme drain cleaners is their eco-friendliness. Without harsh chemicals or harsh detergents to worry about, enzyme cleaners are safe for both your home and environment – plus enzymes are naturally occurring substances that don’t harm ecosystems!

Compatible With Septic Systems

Enzyme drain cleaners are generally safe for septic systems. Unlike chemical products, enzyme-based enzyme cleaners don’t harm good bacteria that help break down waste in septic tanks, making them an excellent option for households that use one.

Slow but Steady

Enzyme drain cleaners work more slowly than their chemical counterparts. Their enzymes require time to break down organic material, so they should only be used as preventive maintenance or on minor clogs. For severe blockages, patience may be required while waiting for their enzymes to do their work.

No Toxic Fumes

As enzyme drain cleaners are chemical-free solutions, they do not emit toxic fumes that could pose health hazards during DIY drain cleaning projects. As such, enzyme cleaners offer safer options than their chemical-based counterparts when cleaning drains yourself.

Ideal for Periodic Maintenance

Enzyme drain cleaners can provide excellent routine maintenance of your plumbing system. The use of enzyme drain cleaners on an ongoing basis can help prevent clogs and keep pipes in good condition, helping prevent costly repair bills in the future.

Understanding Chemical Drain Cleaners

Now that we understand the advantages of enzyme drain cleaners let’s investigate their chemical counterparts. Chemical drain cleaners are powerful solutions designed to quickly unclog drains. Usually containing strong chemicals like sodium hydroxide (lye) or sulfuric acid, chemical drain cleaners have many key characteristics that make them effective. Read on to know “whether chemical drain cleaners are safe?”


Chemical drain cleaners are known for their quick action; they can quickly dissolve hair, grease, paper and other obstructions within minutes, making them the go-to option in emergency situations.

Environmental Implications

Chemical drain cleaners pose one major environmental hazard: their harsh chemicals can harm aquatic ecosystems and pollute water sources if not properly disposed of.

Harsh on Pipes 

Chemical drain cleaners can be harsh on plumbing pipes over time, leading to corrosion or leaks and even possible structural damage. Long-term use or misuse may lead to corrosion and leaks of your plumbing lines.

Chemical Drain Cleaners Can Harm Septic Systems

While enzyme-based drain cleaners may not cause too many issues for septic tanks, chemical-based ones could disrupt the balance of bacteria that exists therein and thus is not advised if you own one.

Danger of Toxic Fumes

Chemical drain cleaners release harmful fumes, which should be handled carefully to prevent inhalation of their fumes. Proper ventilation must be employed when handling these products to protect your health and avoid potential health hazards.

Do Enzyme Drain Cleaners Work? 

The effectiveness of enzyme drain cleaners depends on the nature and severity of the clog you’re facing, but they’re an ideal way to prevent further blockages by keeping your plumbing system healthy – use regularly to keep drains flowing smoothly!

However, in cases of severe blockages caused by solid objects or deposits of non-organic materials like mineral deposits, enzyme drain cleaners may not be sufficient to handle. Under such circumstances, chemical cleaners might be more effective due to their fast-dissolving capabilities.

Are Enzyme Drain Cleaners Safe for Septic Systems?

Yes, enzyme drain cleaners are generally safe for septic systems. In fact, they may even benefit them by breaking down organic matter and hastening natural decomposition processes. Furthermore, unlike chemical cleaners, enzymes will not harm beneficial bacteria essential to maintaining an efficient septic system.

Are Chemical Drain Cleaners Safe?

Although these drain cleaners can effectively clear clogs, their safety is a matter of concern. These cleaners have the potential to damage plumbing and septic systems, and their toxic fumes can pose health risks to nearby residents. If you’ve tried and failed to eliminate drain clogs using enzyme drain cleaners, it’s advisable to turn to professionals. Our drain cleaning experts in Southern, IL are always ready to help.

When Enzyme and Chemical Drain Cleaners Won’t Cut It

Sometimes, neither enzyme nor chemical drain cleaners will do enough to address your plumbing issue, especially when dealing with persistent main drain clogs. Here are a few scenarios when these solutions won’t suffice:

Structural Damage

When roots infiltrate plumbing pipes or cause extensive structural damage, you’ll need professional plumbing repairs or replacements for long-term solutions. In these situations, drain cleaners aren’t enough. Call professional plumbers to repair or replace the damaged pipework sections.

Foreign Objects

When non-organic materials like toys or jewelry become trapped in your plumbing system, drain cleaners likely won’t be enough to dislodge them; you will likely require professional plumbing help with special tools to extract it from there.

Complex Blockages

Complex plumbing blockages that involve multiple layers of buildup or hard-to-reach areas will likely require professional assistance for effective removal. Simply using drain cleaners may not suffice in clearing away these blockages quickly enough.

Choosing the Right Drain Cleaner for Your Plumbing Needs

Enzyme drain cleaners and chemical drain cleaners both play an essential part in plumbing maintenance and repair. By learning the differences between both and when to use each one effectively, you can better maintain your plumbing system. Enzyme drain cleaners effectively deal with clogs and blockages without risking harm to both the environment and the home.
