Drain Jetting in Andover
Andover runs a separate sewer system where misconnections—washing machines plumbed into surface water—are a known local problem that can trigger environmental enforcement. Across postcodes SP10 through SP13, a significant share of homes predate 1920 and carry salt-glazed clay drains prone to root ingress and joint failure. Scheduled jetting, root cutting and CCTV inspections stop these issues before they become emergency call-outs.
Drain maintenance in Andover means scheduled jetting, root cutting, and CCTV inspections to prevent blockages before they happen. For Victorian homes and older clay drains across SP10–SP13, preventative work stops emergency call-outs and environmental compliance issues.
Drainage in Andover — what local engineers know
Southern Water supplies hard water across Andover—this causes limescale buildup in radiators, boilers and soil pipe joints, making descaling a regular maintenance task. Test Valley Council manages drainage planning and environmental compliance; misconnections in the separate sewer system here can trigger enforcement action. Andover sits in a High flood risk zone near the River Test, making sewer backflow a real threat for basement and ground-floor properties. Non-return valves are recommended, but they only work if drains are clear. Regular jetting and root removal keep backwater from pooling inside.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Andover
- Separate sewer system across most of Andover: misconnections (e.g. washing machines plumbed into surface water drains) are a known local issue and can result in environmental enforcement action
- With a significant share of properties built before 1920, salt-glazed clay drainage and lead-solder copper pipework are common — pipe collapse, root ingress and joint failure are recurring call-out drivers.
- Andover has Environment Agency flood warning areas nearby along the River Test corridor — basement and ground-floor properties can face sewer backflow during heavy rain; non-return valves are strongly recommended.

Who's responsible for drains in Andover?
In Andover, responsibility for a blocked or damaged drain depends on where the fault sits. As a homeowner you are responsible for the drains within your property boundary that serve only your home. Since the 2011 private sewer transfer, Southern Water is responsible for shared sewers and lateral drains beyond your boundary — even where they run under private land. Road gullies and highway drainage are maintained by Test Valley.
This matters because it determines who pays. If our engineer's CCTV inspection shows the fault is in a shared sewer, we'll tell you — and you can report it to Southern Water rather than paying for the repair yourself. The separate sewer layout that dominates Andover affects where these boundaries typically fall, and our local engineers know the SP10, SP11, SP12 networks well enough to identify ownership quickly.
