Why a drainage engineer was needed
The booking notes explain that a plumber had reported a blockage requiring a drainage engineer. A completely full manhole is a useful symptom to pass on because it shows where water is collecting in the drainage system.
Working through the inspection chamber
The job photographs document a brick inspection chamber. Existing drainage access gives the engineer a practical route to work into the affected drain. The notes do not identify the specific blocking material.
The clearance work
Aquablast used high pressure water jetting to clear the drains. The completion note records this method directly, so the case can explain the work without adding an unrecorded excavation or pipe repair.
The recorded outcome
The drains were recorded as cleared. This resolves the blockage documented on the visit. A clearance result should be distinguished from a structural assessment, which would require its own findings.
What a homeowner can report
Tell the team whether only one fixture is affected, whether external chambers appear to be backing up, and whether the problem has happened before. Keep access clear and leave chamber lifting and drain entry to the attending engineer.
