Frequently asked questions about drain unblocking.
What causes blocked drains?
The most common causes are grease and food waste, wet wipes and sanitary items, hair and soap build-up, silt, and in some cases root ingress or damaged pipework.
Do you offer emergency drain unblocking?
Yes—Northwest Drainage 24/7 provides emergency drain unblocking 24/7 across the North West.
Will jetting damage my drains?
High-pressure jetting is safe when used correctly by trained engineers. If we suspect fragile or damaged pipework, we’ll advise on the best approach and can complete a CCTV survey if needed.
The drain keeps blocking—why?
Repeat blockages can indicate underlying issues such as pipe damage, incorrect falls, root ingress, or persistent build-up. A CCTV drain survey can pinpoint the root cause.
Can I unblock a drain myself?
Minor slow drainage can sometimes be improved with safe cleaning methods, but if there’s overflow, repeated blockage, or strong odours, it’s best to get professional help to avoid worsening the issue.
