Common causes of a blocked drain
Most blocked drains have a simple cause, and a few checks can find it. Look at which fixtures back up to see how far along the pipe the problem sits. The list below shows the usual suspects.
- ✓ Fat, oil and grease in kitchen waste pipes
- ✓ Wet wipes, nappies and other items flushed down toilets
- ✓ Hair and soap in bath, shower and basin drains
- ✓ Roots that grow into pipe joints
- ✓ Collapsed or misaligned pipe sections
- ✓ Leaves, silt and debris in outside gullies
