Debunking Drainage Myths – Common Misconceptions Every Homeowner Should Know

Plumbing and drainage problems are among the most misunderstood issues households face. Over time, myths and DIY hacks have circulated widely, often making problems worse and leading to expensive repairs.

At Unblockers.net, we handle thousands of drainage callouts across the UK each year. Here are the most common myths we hear, and the truth behind them.

Myth 1: “Boiling Water Fixes Every Blocked Drain”

Pouring boiling water down a sink can loosen very light grease, but it will not remove deeper or solid blockages such as hardened fat, hair, foreign objects, or root ingress. It can even warp or damage PVC pipework.

Reality: Persistent blockages need mechanical clearing such as high-pressure jetting or rodding. Boiling water alone will not resolve the true cause.

Myth 2: “Flushable Wipes Are Safe to Flush”

Despite what packaging says, flushable wipes do not break down like toilet paper. They stay intact, snag inside pipes, and contribute to fatbergs.

Reality: Always bin wipes. Even occasional flushing can lead to major blockages over time.

Myth 3: “A Slow Drain Is Not a Serious Problem”

Many people ignore slow drainage, assuming it is harmless. In reality, it often signals a developing blockage deeper in the system.

Reality: Early intervention prevents full blockages, overflows, and costly repairs.

Myth 4: “Chemical Drain Cleaners Are the Best Solution”

Chemical drain cleaners are harsh, hazardous, and corrosive. They rarely fix the underlying cause and can damage pipes or produce toxic fumes.

Reality: Professional mechanical cleaning or jetting is safer and more effective.

Myth 5: “If the Outside Drain Is Blocked, It Is the Council’s Problem”

Responsibility for drainage depends on whether the pipe is private or shared.

Reality:

• Pipes serving only your home are your responsibility
• Shared drains may be handled by water authorities
• We can help identify which applies to you.

Myth 6: “Tree Roots Only Affect Rural Homes”

Tree roots seeking moisture often penetrate drainage systems, even in dense urban areas.

Reality: Root ingress is a major cause of recurring blockages and pipe damage. A CCTV survey can confirm this.

Myth 7: “Drainage Issues Always Start Inside the Home”

Many homeowners blame internal fixtures, but issues often originate outside, such as in gullies, manholes, or underground piping.

Reality: The blockage could be metres away from the kitchen or bathroom. A full inspection is usually required.
