The Most Common Mistakes in DIY Drain Cleaning

Maintaining the flow of water in the plumbing system of a household is vital in the cleaning of drains for the owner of the home, the plumber that is helping with the issues, and even the contractor managing the maintenance of the property. However, many people tend to do DIY cleans of clogged drains, which do not work out and end up causing more expensive issues. While it could be easy to damage plumbing systems to the point of requiring professionals for cleaning and repairs with plungers and chemicals, the results of that could be more damaging than expected.

In this article, we present some of the root causes of cleaning drains on your own, in addition to common practices that are performed to resolve plumbing system issues.

1. Overusing Chemical Drain Cleaners

One of the most common DIY approaches is reaching for a bottle of chemical cleaner. While these products may seem like a quick fix, they often contain harsh ingredients like sodium hydroxide or sulfuric acid, which can damage your pipes—especially older metal or PVC lines.

Why it’s a problem:

• Over time, repeated use can corrode pipes, leading to leaks.

• The heat produced during chemical reactions can warp PVC piping.

• Chemicals often only clear part of the blockage, meaning clogs return.

Better alternative:

Attempt using a plunger or a drain snake first, as they are less invasive. If a professional drain cleaning service has to be employed, make sure they practice safe plumbing to entirely unclog the drain without any damage to the system.

2. Lack of Suitable Equipment:

Some novice users of plumbing facilities make the mistake of using bent wire hangers, among other improvised tools, to unclog drains. These tools are not only ineffective, but they also damage the pipes in the long run by scratching the insides of the pipes and capturing the debris.

Why it’s a problem:

• Impact on the plumbing system and clogged pipes:

• Can damage pipe linings and fixtures

• Often leads to the retention of debris in the pipes, resulting in incomplete unclogging.

Better alternative:

A clogged drain cleaning service or getting a drain auger are the better options. These specialists use tools like motorized snakes and hydro-jetting, which safely and efficiently clear any plumbing blockages as compared to the regular snakes.

3. Focusing on the Wrong Problems:

Most DIY plumbing fixes are done with the intention of just relieving symptoms, instead of focusing on the source. For instance, the frequent and stubborn blockages in a kitchen sink are symptoms of a bigger problem, which in this case is the grease buildup or the incorrect alignment of the pipes.

Why it’s a problem:

• Temporary fixes lead to repeated clogs.

• Ignoring underlying issues could result in leaks or sewer backups.

Better alternative:

After clearing a clog, inspect the plumbing to determine what caused it. This could mean examining the P-trap, checking for root intrusion in outdoor drains, or calling a plumber for a camera inspection. Early diagnosis can prevent the need for expensive leak repair services.

4. Overusing Tools

Augers or plungers are very handy tools for unclogging drains, but can be very damaging if not handled properly. They can loosen joints, crack fittings, or even rupture pipes.

Why it’s a problem:

• Damaged joints lead to hidden leaks behind walls or under floors.

• Broken seals around toilets or sinks may require costly repairs.

Better alternative:

Check for too much resistance, and if too much, loosen or stop and seek a professional drain cleaning service.

5. Dismissing the Water Supply Shutoff

While unclogging a drain, many people forget to shut the water off before getting to work. A plumber often fixes the problem of a clogged drain and is known for removing the water, but forgets to shut off the water, which in turn can cause flooding.

Why it’s a problem:

• Water damage to flooring, cabinets, and drywall.

• Increased risk of mold growth.

Better alternative:

Always locate and shut off the water supply before attempting significant drain cleaning. For complex plumbing systems, this precaution is non-negotiable.

6. Forget Using Safety Equipment

DIY drain cleaning often involves exposure to bacteria, mold, and unpleasant odors. Without gloves, eye protection, and proper ventilation, you risk skin irritation, respiratory issues, or eye injuries.

Why it’s a problem:

• Exposure to raw sewage and harmful microorganisms.

• Risk of injury from splashing debris or chemicals.

Better alternative:

Wear rubber gloves, safety goggles, and a mask. Even better, leave hazardous clogs to a clogged drain cleaning service that has both the tools and training for safe removal.

7. Pairing Different Cleaners

Some people combine chemical cleaners or mix them with home remedies like vinegar and baking soda. While it might seem like a powerful combination, mixing certain chemicals can produce dangerous fumes or cause violent reactions.

Why it’s a problem:

• Risk of chemical burns and toxic inhalation.

• Potential for pipe damage from excessive heat or reaction pressure.

Better alternative:

Never mix cleaning products. Choose one method—or better yet, use mechanical cleaning like plunging or snaking.

8. Putting Off Calling a Professional

Waiting too long to seek professional assistance can prove to be very costly. A minor clog, for example, can quickly escalate into a plumbing disaster if neglected or improperly fixed.

Why it’s a problem:

• Damp sinks or tubs can be breeding grounds for pests.

• Clogs can lead to pressure buildup, which can cause explosive pipe bursts.

• Filling a simple cleanup can turn into a complicated leak repair service for these delays.

Better alternative:

If your DIY attempts fail after a couple of tries, contact a clogged drain cleaning service. The sooner you act, the lower your repair costs and the less damage to your home.

When Should a Professional be Contacted

Trying to remove minor clogs isn’t a problem; however, there are scenarios that do require a specialist:

• Recurring clogs in a single drain.

• Multiple drains are clogging simultaneously (this hints there might be a main line problem).

• Slow draining accompanied by gurgling or bad smells.

• Water surges into sinks, bathtubs, or showers.

Certified plumbers are equipped with a blockage with a video inspection, hydro-jetting for stubborn removal, and have long-term maintenance plans. Restoring the structure of your plumbing will not only make it work better, but will also extend the life of your pipes.

Conclusion

You can handle small issues with DIY clogged drain cleaning, but tackling these problems yourself can sometimes make things worse. Using too many chemicals, trying to clear the drain too often, and not addressing the real problem are only a few of many mistakes people make, many of which can be avoided with the right tools and knowledge.

Hiring a clogged drain cleaning service for stubborn or recurring problems is the best and most painless option. Not only do these services address your issues, but they can also fix any underlying issues to prevent costly leak repairs later.

Prevention and intervention are better strategies than waiting for the problem to escalate, especially with plumbing. It is best to leave dealing with experts for these issues for the sake of time, money, and peace of mind. The next time you encounter a clog, consider reaching out for professional help instead of tackling it yourself.
