The right way to unblock a toilet

Plenty of people who want to know how to unblock a loo end up going about it all the wrong way.

Constant flushing, using the wrong toilet drain cleaner, inserting a coat hanger and even ignoring the problem and hoping it will go away are not recommended. You don’t want to damage your toilet, make the blockage worse, and pay even more in toilet repair parts. Here we show you how to fix a blocked toilet the right way.

How to unblock a toilet with a plunger

This is one of the easiest ways of unblocking a toilet.

  1. Place the plunger in the toilet
  2. Press firmly multiple times until the blockage has been dislodged
  3. Ensure you disinfect and wash your plunger and toilet

TIP: If you have a clogged toilet, do not keep flushing as you run the risk of overflow resulting in flooding the room.

How to use a drain snake to unblock your toilet

A drain snake, also known as a toilet or drain auger, is another effective way to unclog a toilet.

  1. Unwind and extend the toilet auger and place into toilet
  2. Feed down the toilet until you feel a resistance
  3. Move the coil in an up and down motion to disseminate blockage.  Once the blockage has been cleared, you will notice a reduction in the water levels
  4. Remove the drain snake/auger
  5. Ensure you disinfect and wash the auger coil and toilet
