CCTV Drain Surveys – Accurate Drain Inspection & Diagnosis
Professional CCTV Drain Surveys
Recurring blockages, slow drainage, gurgling pipework or unexplained odours often indicate an underlying issue within your drainage system. While basic unblocking can remove an immediate obstruction, it does not always reveal the root cause of the problem. A CCTV drain survey allows us to inspect your pipework internally using specialist high-resolution camera equipment, identifying the exact source of the fault without unnecessary excavation or disruption.
By inserting a purpose-built drain camera into the system, we are able to assess the internal condition of the pipework in real time. This enables us to detect cracks, joint displacement, root intrusion, scale build-up, collapsed sections or hidden obstructions that would otherwise remain unseen. Instead of relying on guesswork, we gather clear visual evidence to support accurate diagnosis.
At 777 Drains, we carry out professional CCTV drain surveys for both residential and commercial properties, delivering reliable inspection services tailored to the needs of each site. Whether you’re experiencing repeat blockages, investigating potential structural damage, assessing drainage before property purchase, or simply seeking clarity on persistent drainage issues, a camera inspection provides definitive answers.
Our approach focuses on identifying the root cause rather than repeatedly treating symptoms. Once the survey is complete, we explain our findings clearly and outline practical, cost-effective recommendations where required. This ensures you understand exactly what is happening within your drainage system and what steps, if any, are necessary to restore proper long-term performance.
When Is a CCTV Drain Survey Needed?
A CCTV drain inspection is recommended when:
- Blockages keep returning
- Drains remain slow after clearing
- You suspect collapsed or cracked pipework
- Tree roots may be entering the system
- There are signs of ground movement
- You are purchasing a property
- There are foul odours with no obvious cause
Temporary clearing can remove surface obstructions, but it will not identify structural faults. A CCTV survey allows us to pinpoint the issue precisely.
Our CCTV Drain Survey Process
CCTV Drain Inspection
1️⃣ Camera Insertion
We carefully insert a high-resolution drain camera into the pipework via an access point such as a manhole or inspection chamber. The camera travels through the drainage system, capturing detailed internal footage.
2️⃣ Live Footage Monitoring
As the camera progresses, we monitor live video in real-time. This allows us to identify cracks, root intrusion, joint displacement, heavy scale build-up or collapsed sections immediately.
3️⃣ Fault Identification
We pinpoint the exact location and cause of the issue. This prevents unnecessary excavation and ensures any recommended work is targeted and cost-effective.
4️⃣ Clear Reporting
Where required, we provide a clear explanation of findings along with video evidence and practical recommendations for repair or maintenance.
Our structured approach ensures drainage problems are diagnosed correctly the first time.
What Problems Can a CCTV Survey Identify?
A professional CCTV drain inspection can detect:
- Collapsed drain sections
- Cracked or fractured pipework
- Root intrusion breaking through joints
- Misaligned or displaced pipes
- Scale and mineral build-up
- Heavy grease accumulation
- Poor original installation
- Hidden blockages beyond reach of rods
By identifying the root cause early, we help prevent further property damage and repeated unblocking costs.
Avoid Unnecessary Excavation
Without camera inspection, locating drainage faults often involves guesswork. Traditional methods may require exploratory digging, which increases disruption and cost.
A CCTV drain survey removes uncertainty by showing exactly where the issue is located and what is causing it. This allows repairs to be planned accurately and efficiently.
If structural damage is confirmed, our Broken Drain Repairs service provides compliant excavation and pipe replacement where required.
CCTV Surveys After Drain Unblocking
If you have recently had a drain cleared but problems persist, a CCTV inspection may be necessary to investigate further.
Recurring drainage issues are often caused by:
- Hairline cracks developing into fractures
- Tree roots entering through small gaps
- Pipework shifting due to ground movement
- Heavy internal scale restricting flow
Identifying these problems early prevents repeat emergency call-outs.
Pre-Purchase Drain Surveys
If you are buying a property, a CCTV drain survey can provide reassurance that the underground drainage system is in good condition.
Drain repairs can be costly if structural faults are discovered after purchase. A professional inspection gives you clarity before committing.
Commercial CCTV Drain Inspections
We also carry out CCTV drain surveys for:
- Landlords
- Property managers
- Restaurants and hospitality venues
- Offices and commercial buildings
- Construction projects
Commercial drainage systems often experience higher usage levels, making routine inspection valuable for preventative maintenance.
What Happens After the Survey?
Depending on the findings, we may recommend:
- 🔗 High-Pressure Drain Jetting – to remove heavy deposits
- 🔗 Drain Unblocking – for isolated obstructions
- 🔗 Broken Drain Repairs – for structural damage
- Ongoing maintenance where appropriate
We only recommend work that is genuinely required based on camera evidence.
