What You’ll Need to Unblock Your Toilet
Don’t dive in without the right tools for the job. The following is a list of essentials used as part of our 4 DIY fixes below:
- The Right Plunger – Make sure you have a flange plunger (with the internal sleeve) for the best suction.
- A Toilet Auger – This is your “pro-level” tool for reaching deep into the U-bend.
- Hygiene Essentials – Long rubber gloves and a face mask (add goggles for total protection).
- Splatter Zone Prep – Surround the toilet with old towels or newspaper to protect your flooring and reduce the clear up.
- The Natural Reaction – A 200g pack of bicarbonate of soda and 500ml of white vinegar for an eco-friendly unblocking.
- Lubricant – High-quality washing up liquid to help grease and waste move along.
- A 10-Litre Bucket – Necessary for controlled pouring and managing water levels.
- Disinfectant – Have this handy to sanitise the area once the blockage is cleared.
Clearing Your Toilet Blockage – 4 Techniques to Try
The Drainflow team has seen thousands of blockages across our ‘patch’, and – in our experience – most of them can be solved with a bit of patience and the right technique. Here is our recommended “escalation” plan for clearing your toilet.
1. Lubrication & Heat
- Step 1 – Add half a bottle of washing up liquid and wait 15 minutes.
- Step 2 – Pour in a gallon of hot tap water.
- Tip – Never use boiling water as this can crack the porcelain of the bowl.
2. The Power of Suction (Plunging)
- Step 1 – Check that there’s enough water in the bowl to cover the plunger head.
- Step 2 – Plunge a few times, establishing a firm, rhythmic motion.
- Tip – It’s the pull-up motion that often dislodges the blockage, as much as the push-down.
3. The “Eco-Clear” (Vinegar & Soda)
- Step – Tip 200g pack of bicarbonate of soda down the drain. Follow this with approx. 500ml of white vinegar.
- Step – You’ll hear a fizzing sound – that’s the carbon dioxide working to loosen the blockage. Wait until the fizzing stops, then flush with a bucket of hot water.
- Tip – Don’t try this if your toilet bowl is near to overflowing!
4. Mechanical Clearance (The Auger)
A toilet auger is a specialist tool comprising a long rod with a coiled wire at the end. It’s used for reaching blockages that are stuck just out of sight. The auger is shaped to snake through the toilet’s internal trap without getting stuck.
- Step 1 – Guide the protective sleeve of the auger into the bowl.
- Step – Extend the cable until you hit the obstruction, then crank to break it up.
- Pro Tip – If you feel solid resistance that doesn’t budge, stop straight away. It may be a foreign object (like a toy) that needs professional extraction.
Struggling to Clear It? When to Call Drainflow
If you’ve tried the hot water, the vinegar, the auger and the plunger, and you still have a toilet that’s blocked, call for backup! Toilet unblocking is our job, so we have the tools to solve in minutes what might take a DIYer all day.
We recommend calling us straight away if:

- The Water Level is Static – If the water doesn’t budge even an inch after trying our DIY fixes, the blockage is likely a solid ‘plug’ that needs mechanical clearance.
- You Have Slow Drains Elsewhere –This suggests a shared blockage in the main stack, which is a job for our specialist drain jetting equipment.
- You See Wet Patches – Dampness around the base of the toilet or on the ceiling below is a sign of a failed seal or a pipe leak caused by the pressure of the blockage.
- Recurring Issues – If you’re unblocking the same toilet every month, we can run a CCTV drain survey to find out what’s actually going on in there.
Understanding Stubborn Blockages – What’s Going On?
If a plunger hasn’t solved the problem in ten minutes, you’re probably facing one of three drainage issues. Here’s why these problems require a professional touch.
1. Non-Biodegradable Obstructions
Toilets are designed for human waste and paper. Anything else – sanitary products, nappies, or wet wipes – will eventually cause a blockage. These items are designed to be absorbent and strong, which means they expand in your pipes and refuse to break down. We often have to use mechanical augers to physically “hook” these items out of the system.

2. Roots Taking Hold
Tree roots are incredibly persistent. They can exert enough pressure to work through tiny cracks in pipes and grow inside a drainage system for metres. If you have large trees near your drainage, root ingress is a probable cause for a recurring blockage. We don’t just clear the blockage – we use a CCTV drain survey to see where they’re getting in so we can remove them for good and repair the pipes.
