When faced with the annoying problem of blocked drains, it’s totally understandable to want to reach for a chemical drain unblocker as a quick fix; it’s affordable, it’s simple, and it works, right?
While the effectiveness of chemical cleaners isn’t particularly disputed, one problem - aside from these cleaners being the opposite of planet-friendly - is that drain cleaners can actually end up damaging your pipes over time, especially if they’re already old, worn, or frail.
So are chemical drain unblockers worth it? Let’s take a closer look.
A chemical drain unblocker, commonly found in liquid, gel, or powder form, is designed to dissolve blockages in pipes caused by hair, grease, food particles, and other built-up debris. These products typically contain strong chemicals such as sodium hydroxide or sulfuric acid, which react with the blockage material, breaking it down to clear the drain.
Several chemical drain unblockers dominate the market, each with its unique formula. Popular choices often include caustic cleaners, which are alkaline in nature, and oxidising cleaners, which typically contain nitrates, bleach, or peroxides. When it comes to choosing between these products, your choice is usually dependent on the nature of the blockage and the type of pipes in your home.
So, can a chemical drain cleaner damage PVC pipes? While PVC pipes, widely used in modern plumbing, are known for their durability and resistance to corrosion, the heat generated by the chemical reaction of drain cleaners can sometimes soften or even warp these pipes. This is especially true for strong, acid-based cleaners which can cause significant damage to PVC pipes over time.
It’s also important to note that chemical drain cleaners are not selective in their action; while they can effectively dissolve blockages, they can also be harsh on the plumbing system as a whole, and won’t discriminate against your plumbing itself and the object or debris blocking it. For metal pipes, especially older or corroded ones, the acidic nature of some drain cleaners can accelerate the deterioration process, and repeated use of these chemicals can lead to weakening of the pipe walls and joints, potentially leading to leaks and more severe plumbing issues down the line.
All that being said, chemical drain unblockers can be effective for some minor clogs, especially those caused by organic materials like hair or grease. However, we’d stress that their use should really be limited to occasional instances, rather than regular maintenance. It’s also important to carefully follow the instructions and safety precautions on the label, as misuse can lead to pipe damage or even personal injury via toxic fume inhalation.
And most importantly, before using a chemical unblocker, consider the age and condition of your pipes. If your home has older plumbing or if you’re uncertain about the material of your pipes, it's advisable to opt for less aggressive methods, or opt for professional help and - at minimum - an evaluation of your plumbing.
So, why call a plumber than grab a chemical cleaner off the shelf at a supermarket? Here are just a few reasons:
Professional plumbers like us at FS Drainage can accurately diagnose the cause of the blockage, in turn employing the most appropriate method to resolve it without damaging your pipes.
As professionals, we have access to high-grade plumbing tools like drain snakes and hydro-jetting equipment, which are often more effective and less damaging than chemical solutions.
Handling chemical drain unblockers can be hazardous, but we’re trained to handle these substances safely, and our work won’t ever pose a risk to your health and your property.
While chemical unblockers may offer a quick fix, they often don’t address the root cause of the problem. In some cases, it’s a bit like putting a plaster over a large wound; while the bleeding (drain clogging) does stop temporarily, it does nothing to treat the wound, aka the source of the problem.
Repeatedly buying chemical drain unblockers can add up in cost, and if they damage your pipes, you could also end up facing expensive and preventable repairs. Investing in professional services can save money in the long run by ensuring the job is done right the first time with something more appropriate and eco-friendly, like drain jetting.
Ultimately, while chemical drain unblockers can be a temporary solution for minor blockages, they don’t come without substantial risks to your pipes and overall plumbing system. For those facing blocked drains in London, it's often more prudent - and cost-effective in the long-run - to seek professional assistance.
Not all chemical drain unblockers are equally harmful. The level of harm depends on the type of chemical used, the concentration of the product, and the type of pipes you have. Generally, acid-based cleaners are more harmful than enzyme-based ones, especially for PVC pipes or older metal plumbing.
Caution should be exercised when using chemical drain unblockers in a home with a septic system. These chemicals can disrupt the bacterial balance necessary for the septic system to function properly. It's advisable to use products specifically labelled as safe for septic systems.
Chemical drain unblockers should be used sparingly. Frequent use can lead to pipe damage and might indicate a more significant issue with your plumbing that requires professional attention. For regular maintenance, consider less harsh alternatives or professional cleaning services.
