External drain unblocking covers all drainage outside your property. That means gullies, manholes, inspection chambers and underground pipe runs. They carry waste water and surface water to the public sewer.
Outside drains collect leaves, soil, moss, grit and tree roots over time. Because the pipes are underground, problems often go unnoticed. You may only see water pooling in the garden, overflowing from a manhole or backing up into the property.
Our engineers arrive with high-pressure jetting equipment for compacted blockages. They also carry drain rods for blockages they can reach and CCTV cameras for hidden faults. They clear the blockage and flush the full pipe run. Then they inspect the drain for structural issues that might cause trouble later. To compare clearing methods, read how drain jetting differs from drain rods.
The work on an outside drain depends on the length of pipe affected. Tree roots or packed debris may need extended jetting, whereas a simple blockage clears quickly. Request a quote online and describe the problem; the plumber will discuss the job with you.
Since 1 October 2011, the sewerage company has been responsible for most private sewers and lateral drains outside your property boundary. In the Colchester area, that company is Anglian Water. You are generally still responsible for drains that serve only your property. If the blockage is in a shared or public sewer, we can advise you how to report it.
Tree roots are one of the most common causes of external drain blockages in Colchester. Roots seek out moisture, so they can enter pipe joints and cracks. They then grow inside the pipe until they block the flow. Regular CCTV inspections can spot roots early, before they cause a complete blockage.
How often depends on the property, nearby trees and any history of blockages. The plumber can advise on a suitable schedule once they know more.
