How We Restored Underground Flow to Residential Drains
Large residential properties often have complicated pipe networks sitting underground, so when there’s a loss of flow there’s no way you can rely simply on guesswork. For this job in Hertfordshire, Drainflow’s first task was to locate the blockage without causing any damage to the homeowner’s block paving.
We brought in two fully equipped vans, lifted the key manhole covers to discover the site of the bottleneck, and set up our equipment in order to carry out a full system flush and HD camera inspection of the entire run.
High-Pressure Jetting & HD Diagnostic Survey
Once we’d located the backed-up section, we set up our drain jetting equipment to clear the standing water and get a look inside the drainage system.
Getting water moving again solves the initial emergency, but it’s not the end of the job. In order to guarantee long-term reliability, the underground condition of the drain system needs to be checked. We hooked our high-pressure jetting unit to the chamber to clean the walls before feeding our camera down the drain for a CCTV drain survey.
- Flushing the Network – High-pressure water jetted away stubborn grease, scale, and sludge, clearing the main channel.
- Releasing the Silt Blockage – We blasted through a stubborn blockage holding back wastewater in the secondary branch.
- HD Camera Scan – We pushed an HD camera along the full length of the driveway run, inspecting every joint across the clay and PVC pipework.
- Showing the Results – The survey was fully documented; and we handed over the video file as proof that the underground conduit was now in full working order.
Our CCTV camera equipment logs exact meterage, pipe material changes, and the condition of joints throughout the run. We supply residential clients with the raw HD video footage and a clear structural summary. This provides clear and accurate documentation for insurance claims, property sales, or future maintenance records.
No Excavation and No Driveway Damage
Our client was delighted that the job was completed without having to rip up his block paving driveway as part of the job. This is one of the biggest advantages of combining high-pressure jetting with CCTV diagnostics – you avoid unnecessary excavation.
In the past, finding a stubborn blockage beneath block paving meant digging up the driveway with heavy machinery. By operating entirely through existing inspection pits, we were able to clear the obstruction and check pipe integrity without touching a single paving stone. That saves the cost of driveway reinstatement and leaves the site spotless.
