Dealing with a blocked drain is a frustrating household hassle that many Brits face, but rushing into DIY fixes can lead to disastrous consequences. According to Paul Kershaw, owner of Tradefix Direct, over a third of UK residents lack confidence in properly clearing drains, resulting in avoidable errors that damage plumbing and rack up thousands in repair bills. By understanding common pitfalls, homeowners can protect their systems and avoid expensive call-outs.
Top Tips For Clearing Blocked Drains

Steer Clear of Chemical Drain Cleaners for Stubborn Blockages
It might feel tempting to reach for a bottle of chemical cleaner when a blockage won’t budge, but this approach often backfires. These powerful products can corrode pipes if they linger on tough clogs, especially in older setups featuring cast iron or copper materials. Before attempting any remedy, identify your pipe type to sidestep simple yet costly blunders that compromise your entire system.
Stop Flushing Wet Wipes Down the Toilet
Even if labeled as “flushable,” wet wipes are a primary culprit behind sewer blockages, comprising about 93% of the debris according to industry research. Baby wipes top the list of offenders. Unlike toilet paper, they refuse to disintegrate in water, rapidly clumping into impenetrable masses that demand professional removal and can disrupt entire drainage networks.
Resist Applying Too Much Force with a Plunger
Plunging seems straightforward, but excessive pressure is a frequent mistake that harms more than it helps. Overzealous efforts can break seals or fracture porcelain in sinks, baths, and toilets, escalating a minor issue into a major repair job. Opt for a gentle, rhythmic technique instead—it effectively clears clogs without risking additional damage.
Don’t Overlook Slow-Draining Water
A sluggish drain is an early warning sign, not a problem that resolves on its own. Ignoring it allows minor build-ups to evolve into full blockages, necessitating urgent expert help and hefty fees. Address these hints promptly using basic, non-invasive methods to nip issues in the bud and keep costs down.
Simple, Non-Invasive Ways to Unblock Drains at Home
Before calling a professional, try these gentle, tool-free techniques to clear minor clogs safely. They work best on early-stage or slow-draining issues and won’t harm pipes or seals.
1. Boiling Water Flush
- Boil a full kettle of water.
- Pour it slowly down the drain in 2–3 stages, allowing 10–15 seconds between pours.
- The heat loosens grease, soap scum, and small organic build-ups.
- Tip: Use only for metal pipes; avoid with PVC if water is scalding to prevent warping.
2. Baking Soda & Vinegar Reaction
- Pour ½ cup of baking soda directly into the drain.
- Follow with 1 cup of white vinegar.
- Cover the plughole with a plug or cloth for 15–30 minutes to trap the fizzing action.
- Flush with hot (not boiling) tap water.
- This natural fizz breaks down fatty acids and light debris without chemicals.
3. Manual Removal with a Wire Hanger
- Straighten a wire coat hanger, leaving a small hook at one end.
- Gently fish into the drain to pull out hair, soap, or visible gunk.
- Work carefully to avoid pushing blockages deeper.
- Rinse with warm water afterward.
4. Plunger with Proper Technique
- Fill the sink or bath with enough water to cover the plunger’s rubber cup.
- Place the plunger over the plughole and press down gently to create a seal.
- Pump steadily up and down 10–15 times without breaking the seal.
- Release slowly and check flow. Repeat if needed.
- Key: Controlled rhythm, not force, prevents damage.
5. Dish Soap & Hot Water for Grease Clogs
- Squirt ¼ cup of grease-cutting dish soap down the drain.
- Follow with a kettle of hot (not boiling) water.
- Wait 5 minutes, then run the tap to flush.
- Ideal for kitchen sinks clogged with fat or oil.
6. Salt & Baking Soda Overnight Soak
- Mix ½ cup table salt with ½ cup baking soda.
- Pour into the drain and leave overnight.
- Flush with hot water in the morning.
- The abrasive combo helps shift stubborn residue gently.
When to Stop: If water still won’t drain after 2–3 attempts or you notice foul smells/backflow, call a plumber. Persistent issues may signal deeper pipe problems.
By avoiding these missteps, you can maintain your plumbing’s integrity and save significantly in the long run.
