Toilet discharge pipes can get blocked when you put the wrong things down the toilet, such as sanitary pads, food scraps, rags, cans, bottles, paper, fat and grease. Similarly, waste water pipes from basins, sinks, and laundry tubs can also be clogged by food waste, tea leaves, grease, lints, hair and other rubbish.
To unblock your sink, shower or tubs, you must first remove all rubbish that you can see. Then use a large rubber cup plunger to finish unblocking the pipe. Your plunger should be of a heavy and larger rubber cup that is connected with a handle on the closed side.
