Toilet Won't Flush? How to Handle a Blockage
A blocked toilet or drain is a nightmare. Try these safe DIY steps before calling out an emergency plumber.
There are few things worse than flushing the toilet and watching the water level rise dangerously close to the rim. A blocked toilet is a stressful emergency that needs immediate attention.
What's Causing the Issue?
The vast majority of blockages are caused by flushing things that shouldn't go down the pan: wet wipes (even the "flushable" ones), sanitary products, excessive toilet paper, or children's toys. In older properties, tree roots infiltrating the external drainage pipes can also cause severe backups.
What You Can Do Right Now
- 1. Stop flushing: If the water level is high, do NOT flush again. You will overflow the bowl.
- 2. Use a plunger: A traditional flange plunger (not a flat sink plunger) is your best tool. Ensure a good seal and push down firmly and pull up sharply to dislodge the blockage.
- 3. Hot water and soap: Pouring a generous amount of washing-up liquid followed by hot (not boiling) water from a height can sometimes lubricate and break down paper blockages.
When It Becomes Serious
If multiple fixtures are backing up (e.g., you flush the toilet and water comes up in the shower tray), the blockage is further down the main soil stack or external drain. This is a severe sanitation issue that risks flooding your home with sewage.
When to Call an Engineer
If plunging doesn't work, or if the blockage is in the external drains, you need a professional with specialized equipment like drain rods or a mechanical auger.
