When a pipe gets blocked, either completely or partially, going to the supermarket and grabbing some drain cleaner can seem like a very tempting option. However, for a number of reasons, this is only a half measure in the short-term, and a costly one in the long-term.

In this blog, we will outline why drain cleaner should be avoided at all costs, as well as other options you can use when your drains are facing a clog.

Why You Should Avoid Drain Cleaner

Chemical Drain Cleaners are not a good option because:

  • They will destroy your pipes.
  • They don’t do a particularly good job.
  • The liquid and fumes are dangerous.

Why You Should Avoid Drain Cleaner

Corrosive Chemicals and Your Pipes

Drain cleaning chemicals are corrosive. That is how they work; they corrode away anything within your pipes that they come into contact with. However, they will also very quickly start to work their way through your pipes.

Of course, they won’t rot them away entirely upon your first application, but they can do a significant amount of damage over time. After just a few applications, even sparingly, the lifespan of your pipes will be significantly reduced.

Are They Effective?

There is no yes or no answer to this question. They are more effective than some alternatives you could carry out yourself, but they aren’t anywhere near as effective as a professional service.

In comparison to an enzyme cleaner, for example, they will do a more complete job. Enzyme cleaners will only break down natural substances but will do nothing to dislodge your child’s misplaced toys!

Depending on what blockage you are dealing with, they have the potential to be more effective than a plunger. Plungers are relatively limited in terms of cleaning residue off the sides of your pipes.

However, in comparison to professional water jetting, drain cleaners won’t do even 10% of the job. Using only remote access, in a couple of hours, we can have your entire system completely flushed, significantly reducing the risk of a critical drainage failure.

Are Drain Cleaners Safe?

The short answer is no, not particularly. For a start, they can quickly cause intense irritation if they come into contact with your skin. Causing itchiness and blotches; not dissimilar from corrosive bleaches.

Fumes can also be an issue. Especially when you are using the chemical in an enclosed space such as a small bathroom.

Drain cleaners are by no means a death sentence, but they are still far from pleasant. The less dangerous chemicals you have around the home, the better!

What Are the Alternatives?

There are countless alternatives to using drain cleaning chemicals, and while many of them might not be quite as effective they are still preferable due to the damage drain cleaners can cause.

What Are the Alternatives?

As we previously mentioned, enzyme cleaners can be an excellent alternative to drain cleaning chemicals. But while drain cleaners will corrode too much, enzyme cleaners can corrode too little. Since they only affect organic substances, they might not actually address the issue.

Plunging is yet another technique, but again its applications are somewhat limited. It can deal with a specific clog when it is near the surface or a particular entry point, but it won’t do much more than that. For more effective results, the only option is to book in some professional high-pressure water jetting.

What is High-Pressure Water Jetting?

High-pressure water jetting is by far the best way to get rid of blockages within your pipes while flushing away all other problematic debris clinging to the side of your pipes. Water jetting boasts a few key advantages:

  • Cost-Effective: Since we only use water during the process, we can save money on expensive chemicals.
  • Safe: The water will make quick work of anything that is clinging to the sides of your pipes but is utterly harmless to the pipes themselves whether they are PVC or metal.
  • Efficient: In just a couple of hours we can arrive at your home, set up our equipment, clean your system, and be packed up and gone.

There are countless reasons as to why a drainage system can malfunction, so we can’t guarantee that flushing your system will avoid any sort of faults. However, the majority of critical failures do come from blockages and clogs, which means water jetting will significantly reduce the risk of any unwelcome surprises!

    Explained everything so simply.

    I had no clue what was going on with our pipes but they explained it all so clearly. Felt completely reassured the whole time and appreciated how patient they were with my questions.

    They were recommended by a mate and didn’t disappoint. From the first phone call to the final clean-up, it was clear they knew their stuff. We felt confident we were in good hands the entire time.

    Surprisingly brilliant.

    Never thought I’d be raving about a drain company but here we are. They were just that good. Helpful, friendly, honest – and most importantly, they fixed the problem without any stress.

    Garden sorted, no more flooding.

    Cheers to Clark Drainage for getting our garden sorted after that downpour. Great job. We’d tried a few things ourselves with no luck, but they came in, identified the issue quickly, and had the drainage working perfectly again.

  • 17/08/2025

    Quick turnaround and sorted fast.

    The lads came out next day and fixed the issue in half an hour. It had been bothering us for weeks, so to see it sorted that quickly was honestly a huge relief.

    Did it right first time.

    We’d had other companies round who couldn’t fix it. Clark Drainage had it sorted in one visit. The difference in professionalism and competence was night and day. Absolutely brilliant from start to finish.

    Proper pride in their work.

    It’s not glamorous work but they do it with a smile and real pride. Can’t say I’ve ever seen someone so happy clearing a drain, but they made the whole thing stress-free and even a bit fun.
