Common cctv drain surveys problems
- ✓ Cracks in ageing pipes
- ✓ Joints that have slipped out of line
- ✓ Roots growing in at connections
- ✓ Unknown pipe routes under older buildings
- ✓ Drains backing up in heavy rain near the river
A CCTV drain survey sends a small waterproof camera along the pipe, so the footage shows cracks, roots, loose joints and silt that nobody can see from above. You get a clear picture of the drain instead of a guess.
Witham is a market town on the River Brain, west of Colchester. We cover Newland Street, Chipping Hill and the estates around the edges of the town.
A survey suits drains that block again and again. It also helps before you buy a house, because drain faults rarely show at a viewing. Damp patches or sunken ground along a pipe run are another reason to look. The written report records what the camera found.
Properties around Newland Street and Chipping Hill may have clay, plastic or a mix of both. The survey report records which type each run uses.
Homes near a river may see drains back up in heavy rain. When a river rises, drain outfalls can work less well, so drains may surcharge. Older homes may have clay pipes, while newer ones often have plastic.
Read about cctv drain surveys in detail, or look at the Witham drainage hub for local background. The Colchester drainage hub shows how the same service works in the main town. Although each fault differs, drain jetting in Witham often follows.
A survey helps separate a damaged pipe from a flooded outfall, since both can look alike after rain. The camera shows cracks that let groundwater in.
Homes near a river can see drains surcharge in heavy rain when the river level rises. If problems follow wet weather, a plumber can assess whether a non-return valve would help, although a survey comes first.
