Toilet trash plugs up London pipes
Tonnes of congealed fat, wet wipes, food and other rubbish have blocked water pipes in West London.
This massive blockage, called a 'fatberg', was as long as a passenger plane and took workmen four days to clear.
They had to blast it with high pressure hoses to break it up.
If left there, it could have flooded homes and businesses with tonnes of sewage.
