When your sink starts draining slowly or your shower turns into a foot bath, your first instinct might be to grab a chemical cleaner or try a quick DIY hack. While these fixes may seem convenient, the truth is that many common drain cleaning myths can do more harm than good—and they could end up costing you more in the long run.
At our company, we’ve seen it all—from pipes warped by boiling water to entire drainage systems compromised by repeated chemical use. Let’s take a look at some of the most widespread myths about drain cleaning and explain why calling a professional is the best way to protect your plumbing—and your wallet.
Myth #1: Chemical Drain Cleaners Are a Safe and Effective Fix
One of the most common mistakes we see is the overuse of chemical drain cleaners. These products promise quick relief from clogs, but what they don’t tell you is that they can severely damage your plumbing system.
Most chemical drain cleaners contain harsh ingredients like lye or sulfuric acid. These substances are corrosive—not just to clogs, but to your pipes. Repeated use can weaken pipe walls, leading to cracks, leaks, and premature failure. If you have older or plastic piping, the damage can be even more severe.
Plus, chemical cleaners are harmful to the environment and unsafe for homes with septic systems. They can kill the beneficial bacteria in your tank, disrupting the natural breakdown of waste and leading to costly septic repairs. Skip the chemicals. If a clog doesn’t clear with a plunger or simple hand auger, it’s time to call a professional.
Myth #2: Boiling Water Is the Best Way to Clear Drains
Another popular DIY trick is pouring boiling water down the drain to melt away clogs. While this might sound harmless—or even clever—it can actually cause serious damage, especially if your plumbing system includes PVC pipes.
PVC piping is commonly used in residential plumbing. It’s strong and durable, but it’s not designed to handle extremely high temperatures. Boiling water can soften or even melt PVC over time, especially at joints and bends, leading to leaks and warping that require costly repairs.
Even with metal pipes, boiling water is rarely a long-term solution. It might break up a bit of grease, but it won’t address deeper blockages, hair buildup, or solid obstructions. The safer alternative? Our professional-grade equipment can clear clogs without damaging your pipes or relying on extreme heat or chemicals.
Myth #3: If the Drain Is Moving Slowly, It’s Not an Emergency
A slow drain might not seem like a big deal, but it’s often a warning sign of a much larger problem. Waiting too long to deal with it can allow buildup to worsen, eventually leading to a full blockage—or worse, a backup that floods your home.
Hair, soap scum, grease, and even tree roots growing through pipes can all contribute to slow drainage. Without the right tools and training, it’s hard to know what you’re dealing with. That’s where we come in. Our technicians use camera inspections and advanced diagnostics to identify the exact cause of your slow drain and fix it the right way—before it becomes an expensive mess.
