Clogged Drain? Why You Should Never Use Chemical Cleaners

August 28, 2025

It’s a frustratingly common scenario for every Phoenix homeowner. The kitchen sink is full of murky water that won’t go down, the shower drain has turned into a small pond during your morning routine, or the bathroom sink is gurgling ominously. Your first instinct might be to drive to the nearest store and grab a bottle of liquid chemical drain cleaner. It seems like a fast, cheap, and easy fix. But is it?

While the promise of a quick solution is tempting, reaching for that bottle can be one of the most damaging things you do to your home’s plumbing system. These harsh chemicals often do more harm than good, leading to costly, long-term problems that a simple clog never would have caused.

As Phoenix’s trusted plumbing experts, the team at APES HVAC & Plumbing has seen the devastating aftermath of chemical drain cleaners firsthand. Before you pour another dollar down the drain, let’s break down what’s really happening inside your pipes and why a professional solution is always the smarter choice.

 

How Do Chemical Drain Cleaners Actually Work?

 

To understand the danger, you first need to understand the science. Liquid drain cleaners are essentially a chemical reaction in a bottle. They use incredibly powerful and corrosive agents to generate heat and dissolve the clog. There are three main types:

  • Caustic Cleaners: These contain substances like lye (sodium hydroxide). They are alkaline, and their chemical base generates heat that dissolves grease and soap scum into a soap-like substance that can (in theory) be washed away.
  • Oxidizing Cleaners: These use chemicals like bleach to oxidize the clog, causing it to lose electrons and break apart. They are often used for clearing hair and food-based clogs.
  • Acidic Cleaners: These are the most powerful and dangerous, often available only to professionals. They use potent acids like sulfuric acid to rapidly melt through hair, grease, and even paper.

The problem is that these powerful chemical reactions don’t just target the clog—they attack everything they touch, including your pipes.

 

The Hidden Damage: A Slow Disaster for Your Plumbing

 

While you might see the water slowly start to drain, you can’t see the damage being done inside your plumbing system.

1. Irreversible Damage to PVC and ABS Pipes Most modern Phoenix homes have plumbing made from PVC (polyvinyl chloride) or ABS (acrylonitrile butadiene styrene) plastic. While durable, these pipes are not designed to withstand the intense heat generated by chemical drain cleaners. The chemical reaction can heat up to the point of boiling, causing the plastic pipes to soften, warp, or even melt. This can weaken joint seals, leading to slow, hidden leaks behind your walls or under your foundation.

2. Corrosion and Failure of Metal Pipes If you live in an older home, you may have galvanized steel or cast-iron pipes. The caustic and acidic nature of drain cleaners is relentlessly corrosive to metal. Each time you use them, the chemicals strip away a small layer of the pipe’s interior. Over time, this corrosion thins the pipe walls, leading to pinhole leaks, burst pipes, and the eventual need for a very expensive repiping project.

3. They Make the Problem Worse on Tough Clogs Chemical cleaners are only effective on soft blockages like hair and grease. They do absolutely nothing against solid obstructions, such as:

  • Tree root intrusion in your main sewer line.
  • A flushed foreign object (like a child’s toy).
  • Heavy mineral scale buildup from Phoenix’s hard water.

When the chemicals fail to clear the clog, they become trapped in your pipes, sitting in one spot and continuously eating away at the pipe material, concentrating the damage in one vulnerable area.

4. They Mask the Real Issue A recurring clog is often a symptom of a larger problem, like a partially collapsed sewer line, a major blockage further down the system, or improper drain slope. By using chemicals to create a temporary, narrow path through the clog, you are simply treating the symptom and ignoring the underlying disease. This allows the real problem to get worse over time.

 

The Professional Difference: Safe, Effective, and Definitive Solutions

 

When you call a licensed plumber from APES HVAC & Plumbing, you’re not just getting a quick fix—you’re getting a real, long-term solution that protects the integrity of your plumbing system.

Step 1: Professional Diagnosis with a Camera Inspection Instead of guessing, we find out exactly what’s causing the clog and where it is. We can use a specialized, high-resolution sewer camera to travel through your pipes and get a clear view of the problem. This allows us to identify if it’s a simple clog, a foreign object, tree roots, or a damaged pipe, ensuring we use the right tool for the job.

Step 2: Mechanical Clearing with a Drain Auger (Snake) For most common clogs, a professional drain auger is the perfect tool. Unlike a flimsy drain snake from a hardware store, our professional-grade machines have the power and length to effectively break up or retrieve the blockage without scraping or damaging your pipe walls.

Step 3: The Ultimate Clean with Hydro-Jetting For tough clogs or pipes with heavy buildup, hydro-jetting is the most effective solution available. This process involves using a specialized hose that shoots streams of high-pressure water into the pipe. Hydro-jetting doesn’t just punch a hole through the clog; it completely scours the entire interior surface of the pipe, blasting away years of accumulated grease, sludge, and mineral scale from Phoenix’s hard water. It restores your pipe’s full flow capacity and is the single best way to ensure a clog doesn’t come back anytime soon.
