Common causes of a blocked drain
Most blockages have a plain cause. Check which fixtures back up, because that shows how far along the pipe the problem sits. The list below covers the usual ones.
- ✓ Fat, oil and grease in kitchen waste pipes
- ✓ Wet wipes, nappies and other items flushed down the toilet
- ✓ Hair and soap in bath, shower and basin drains
- ✓ Roots that grow into pipe joints
- ✓ Cracked or slipped pipe sections
- ✓ Leaves, silt and litter in outside gullies
