A blocked toilet is one of the most stressful household emergencies — especially in a holiday rental or hotel where guests are waiting. The video above walks through three proven methods, and this guide breaks down exactly what to do, step by step, so you can handle the situation calmly and without calling a plumber. Whether you are managing a villa in Crete or a city apartment in Athens, these techniques work on standard Greek plumbing.
Why Toilets Block in Greek Properties
Greek plumbing — particularly in older island properties and apartment blocks — often uses narrower-diameter pipes and tighter bends than northern-European standards. Wet wipes, cotton wool, and excess toilet paper are the most common culprits, but scale build-up and low water pressure can make even minor blockages worse over time.
In rental properties with frequent guest turnover, foreign objects and non-flushable wipes are a weekly hazard. Keeping a plunger and a bottle of enzyme-based drain cleaner on site prevents a simple clog from becoming a plumber call-out.
What You Need Before You Start
Gather your tools before lifting the lid: a standard cup plunger or a flange plunger (better for toilets), rubber gloves, old towels or newspaper to protect the floor, and a bucket. If you do not own a plunger, a mixture of hot water and washing-up liquid can work as a first-aid measure. A toilet auger (a flexible hand-cranked snake) is worth buying for persistent or recurring blockages.
How to Unblock a Blocked Toilet
- 1
Stop the water and protect the floor
Before anything else, lift the cistern lid and press down the flapper valve to stop water entering the bowl. Place old towels or newspaper around the base of the toilet to catch any overflow. Put on rubber gloves — this is non-negotiable.
- 2
Try hot water and washing-up liquid first
Squirt a generous amount of washing-up liquid into the bowl, then slowly pour in about half a bucket of hot (not boiling) water from waist height. The heat and soap help break down the blockage and lubricate the pipe. Wait 10 minutes, then flush. This alone clears the majority of soft blockages.
- 3
Use a plunger with the right technique
If water alone did not work, fit a flange plunger firmly over the outlet hole at the bottom of the bowl, making sure it forms a complete seal. Push down slowly to expel air, then pull back sharply to create suction. Repeat 10–15 times with a rhythmic push-pull motion rather than aggressive jabbing. Flush to test — repeat a second round if needed.
- 4
Deploy a toilet auger for stubborn clogs
Feed the flexible cable of the auger into the bowl outlet, rotating the handle clockwise as you push. When you feel resistance, keep rotating to either break up the blockage or hook it so you can pull it back out. Withdraw the auger slowly and flush with a full cistern. An auger reaches blockages that a plunger cannot reach.
- 5
Know when to call a plumber
If all three methods fail, or if multiple fixtures (shower, basin) are also draining slowly at the same time, the blockage is likely in the main soil stack rather than the toilet itself. Turn off the water supply to the toilet using the isolation valve on the supply pipe, and call a licensed plumber. Do not keep flushing — repeated flushing risks overflow and water damage.

FAQ
- Can I use boiling water to unblock a toilet?
- Avoid fully boiling water. It can crack a porcelain toilet bowl or damage older wax seals. Use hot tap water or water that has been left to cool for a minute or two after boiling — hot enough to soften a blockage but safe for the toilet.
- What if I do not have a plunger?
- The washing-up liquid and hot water method (Step 2) often works without any tools. Alternatively, mix half a cup of baking soda with one cup of white vinegar, pour it into the bowl, let it fizz for 30 minutes, then follow with hot water. Both approaches are useful for properties awaiting a proper plunger.
- How do I prevent my toilet from blocking again?
- Only flush toilet paper — no wet wipes, cotton wool, sanitary products, or paper towels even if they claim to be flushable. In rental properties, add a small bin next to the toilet with a clear sign in multiple languages. Descaling the bowl every few months also keeps the outlet channel clear in areas with hard water.
