How to unblock a toilet with or without a plunger
Don't panic! Whether you have a plunger handy or need alternative methods, here is how to tackle a blocked toilet effectively before calling CleverWorks for a CCTV drainage survey in London.
A blocked toilet is a stressful situation that no one wants to deal with. The water level rises ominously, and panic sets in. But before you reach for the phone to call a national chain, take a deep breath.
Many toilet blockages can be resolved with a few simple DIY techniques. If these fail, the local experts at CleverWorks are ready to help with a professional CCTV drainage survey to pinpoint the exact cause of the problem across London.
Method 1: Using a Plunger (The Best Way)
If you have a plunger, this is your best bet. A flange plunger (the one with the extra rubber flap at the bottom) is specifically designed for toilets.
- Ensure there is enough water in the bowl to cover the plunger cup. If not, add a little water from a bucket.
- Place the plunger over the hole at the bottom of the bowl, creating a tight seal.
- Push down gently at first to expel the air, then plunge vigorously up and down for 15-20 seconds.
- Break the seal and pull the plunger out. The water should drain away. If not, repeat the process.
Method 2: The Hot Water and Washing Up Liquid Trick
No plunger? No problem. This method uses heat and lubrication to break down the blockage.
- Squirt a generous amount (about half a cup) of washing up liquid into the toilet bowl. Let it sit for 10 minutes to seep into the blockage.
- Fill a bucket with hot (but not boiling) water. Boiling water can crack the porcelain bowl.
- Pour the hot water into the bowl from waist height. The force of the water combined with the soap can often dislodge the blockage.
- Wait a few minutes to see if the water level drops.
Method 3: The Baking Soda and Vinegar Volcano
If the soap trick didn't work, try a chemical reaction.
- Pour one cup of baking soda into the toilet bowl.
- Slowly pour in two cups of white vinegar. It will fizz and bubble up.
- Let the mixture sit for 30 minutes to break down the blockage.
- Follow up with a bucket of hot water poured from waist height.
When to call CleverWorks for a CCTV Drainage Survey
If you have tried plunging and the hot water tricks and your toilet is still blocked, or if water is backing up into your bath or shower when you flush, the blockage is likely deep within your main drainage system. You may need emergency drain unblocking.
At CleverWorks, we use state-of-the-art cameras to conduct a CCTV drainage survey. This allows us to see exactly what is causing the blockage—whether it's a severe build-up of wet wipes, tree root ingress, or a collapsed pipe—without any unnecessary digging. We provide fast, fixed-price solutions across London and the UK.
Frequently Asked Questions
Why does my toilet keep blocking?
The most common causes of a blocked toilet are flushing non-flushable items like wet wipes, sanitary products, or excessive amounts of toilet paper. It can also be a sign of a deeper issue in your main drain.
Can I use a wire coat hanger to unblock a toilet?
Yes, you can use a straightened wire coat hanger to try and hook or break up a blockage near the surface. However, be extremely careful not to scratch the porcelain bowl.
