Toilet won’t flush properly #1

My toilet won’t flush properly” is a common cry for help in our emergency plumbing business.

We then ask, Do you mean the dirty water won’t flush away?
If the answer is yes and it looks like this, then you have a blocked drain and you need a blocked drain expert quickly

However, if you press the Full and Half flush buttons and they don’t effectively clear the toilet bowl, that means, there isn’t enough water in the toilet cistern to do the job or the buttons just don’t work or the cistern just won’t refill or it’s slow to fill.

Then I know how to fix the toilet that won’t flush properly.
