FAQ’s

FAQs — CCTV Drain Surveys Bristol

1) What does a CCTV drain survey actually show me?
A live video of the inside of your drains with timestamped footage, still images, defect locations and depths, flow direction, and a clear pass/fail summary. You’ll get a written report with mapped runs, recommendations, and repair priorities.

2) When do I need a CCTV drain survey instead of just unblocking?
If the blockage keeps returning, you’ve had smells or flooding after rain, are buying/selling a property, planning a build-over or extension, or an insurer/landlord has asked for evidence.

3) What deliverables do I receive after the survey?
HD video files, still photos, a PDF report with defect codes, a plan of the system, depth/location data from the sonde locator, and a plain-English summary with quotes for any remedial works.

4) Do you follow a recognised reporting standard?
Yes—defects are coded to WRc/MSCC standards so insurers, surveyors and local authorities accept the findings.

5) Can you survey all pipe sizes?
For homes and small sites we use push-rod cameras (typically 32–150 mm). 

6) How do you pinpoint where a defect is from the video?
Each camera has a sonde transmitter; we trace it above ground with a locator to record exact position and depth—useful for precise, minimal digging or targeted lining.

7) Will you clear the line first if it’s blocked so you can survey properly?
Yes—if the pipe isn’t clear, we’ll HPWJ (high-pressure water jet) to clean to full bore, then re-survey so the results are accurate and the video is usable for approvals or claims.

8) I’m buying a house in Bristol—do you do Homebuyer drain surveys?
Absolutely. We provide a Homebuyer CCTV survey with a risk rating, life-expectancy notes for clay vs plastic sections, and costed options if issues are found—delivered fast so you don’t hold up conveyancing.

9) Do you handle build-over/extension surveys for the council or Wessex Water?
Yes—pre- and post-build CCTV surveys with maps, depths, and WRc coding suitable for build-over agreements and adoption checks. We align the report to what the authority or Wessex Water expects.

10) Can you find drain routes I can’t see on old plans?
Yes—sonde tracing, dye tests, and where needed smoke testing will map unknown runs, locate buried chambers, and confirm which line connects to which outlet.

11) What if you find roots, cracks, or a displaced joint?
Your report will include photos, location, depth and severity, plus fix options: local patch repair, full-length lining, root cutting and re-survey, or targeted excavation if structural failure is severe.

12) How fast will I get the report?
For typical domestic surveys we aim for same-day video share and next-day PDF report. Complex/commercial sites may need longer; we’ll tell you on arrival.

13) Is a CCTV survey messy or disruptive?
No. We work via existing chambers. We use floor protection, isolate water where necessary, clean down after, and leave everything as we found it.

14) Do you survey rainwater drains and gullies as well as foul lines?
Yes—foul and surface water lines, including driveway/roof gullies, soakaways and ACO channels. We’ll flag any misconnections (e.g., appliances wrongly discharging to surface water).

15) Can the survey help with insurance claims?
Yes—insurers expect WRc-coded evidence with precise locations and photos. We supply exactly that and can provide a contractor’s quote and a post-repair sign-off survey.

16) What if there’s no easy access to the drains?
We’ll locate or expose the nearest viable access point, or create a temporary one if required, then reinstate neatly. We’ll explain this on site before we start.

17) Do you cover the whole of Bristol and nearby?
Yes—BS1–BS16, BS20–BS21, BS30–BS31, BS32–BS37, plus Portishead, Clevedon, Nailsea, Keynsham, Thornbury, Yate, Bradley Stoke, Chepstow and surrounding areas—same-day where possible.

18) What qualifies your engineers to report on my drains?
Our surveyors are experienced drainage engineers trained in WRc/MSCC coding, HPWJ, sonde location and confined-space awareness, with calibrated equipment and documented procedures.

19) Will you show me the footage during the visit?
Yes—live on screen while we’re there, with key frames saved into the report. You’ll see what we see before we leave.

20) Can you return to verify repairs after another contractor has worked on the drain?
Yes—post-repair/post-lining sign-off surveys with before/after evidence, updated mapping and a clean bill of health if it passes.

21) How do I prepare for a survey visit?
Clear access to chambers if you can, keep a parking spot near the line to be surveyed, and avoid heavy water use for the hour we’re testing. We’ll handle everything else.

22) Do you charge a call-out fee for CCTV surveys?
No call-out fee. We agree a fixed price on arrival once we’ve confirmed the scope. If the line needs jet cleaning first, we’ll price that clearly before proceeding.

23) Can you coordinate with my builder, surveyor or managing agent?
Yes—send their contact details and we’ll brief them directly, share plans and video links, and align the survey to their requirements.

24) What problems do you see most often in Bristol drains?
On older stock: root ingress at clay joints, displaced collars, interceptor traps holding silt, and scale lips that snag wipes. On newer systems: poor falls, debris in new builds, and misconnections.

25) How do I book a CCTV drain survey today?
Call 0117 427 4565 or email admin@flowsuredrains.co.uk with your postcode, a short description, and any deadlines (homebuyer, build-over, insurance). We’ll confirm the earliest arrival window.
