5 Common Mistakes People Make When Dealing with a Blocked Drain

Did you know that unclogging drains is one of the most common home repairs in the UK? Whether it’s a kitchen sink clogged with grease or a bathroom drain slowed by hair and soap buildup, these blockages can disrupt daily routines and even cause long-term damage if left untreated.

While it’s tempting to grab a makeshift drain snake, going the DIY route can often do more harm than good. From using the wrong tools to accidentally pushing the clog deeper, well-meaning efforts can quickly turn a minor issue into a major plumbing problem.

Here are five common mistakes people make when dealing with a blocked drain:

Mistake 1: Pouring Chemicals Down the Drain

Dealing with a stubborn drain clog is frustrating, especially when you’ve tried everything. While chemical drain cleaners are marketed as the solution to all your drainage issues, it can actually do more harm than good. Caustic or alkaline drain cleaners generate heat to dissolve clogs. This heat can corrode metal pipes over time, especially with repeated use. Frequent use also has the potential to weaken joints, seals, and older plumbing systems, which can lead to expensive replacements and repairs. 

Mistake 2: Ignoring Early Warning Signs

Serious plumbing issues aren’t always visible during a quick inspection, which unfortunately makes them easier to ignore—until they become a much bigger problem. Strange gurgling noises, bad smells, or slow drainage are all red flags that you shouldn’t ignore. Keeping an eye out for any warning signs can help you avoid costly repairs and headaches. It’s always better to catch a plumbing issue early and address it before it snowballs into something catastrophic. Here are a few more early warning signs to keep an eye on: 

• Unexplained water stains which can signal leaks 

• Frequently clogged drains and toilets 

• A sudden increase in your water bills

Mistake 3: Using the Wrong Tools

Have you ever tried to remove a blockage with a stick or makeshift hanger? Unfortunately, these methods are all too common and can actually have a detrimental effect on your plumbing system. While your intention may be to remove the blockage, you might actually compact the block or push it further down the pipe, making it harder to reach or remove. 

Certain materials, such as wire hangers, are not designed for plumbing. The edges or pressure from forcing the hanger into your drain can scratch, crack or puncture your pipes. Use a plunger or drain snake - or better yet, leave it to the professionals with the right equipment. 

Mistake 4: Repeatedly Flushing the Problem

When a toilet is blocked or draining slowly, your natural reaction is to flush it again, hoping it will clear itself. However, this is a common plumbing mistake, especially if repeated again and again. Avoid repeatedly flushing the problem as this sends more water into the bowl, and if the blockage remains, the water has nowhere to go. This can quickly lead to overflowing, which can cause a mess and water damage.

Mistake 5: Delaying a Professional Call-Out

It’s tempting to put off calling a plumber in the hope that the issue will “sort itself out.” But waiting too long can turn a small, manageable problem into a major plumbing disaster. Whether it’s a slow leak or a mild clog, a professional can quickly locate the source of the issue and resolve it efficiently—saving you time, money, and unnecessary headaches.
