Blocked Toilets in Andover
Andover's housing stock is predominantly Victorian and Edwardian terraces with modern extensions, spread across SP10, SP11, SP12 and SP13. The town's separate sewer system means that toilet and basin blockages here often need careful diagnosis to rule out misconnections into surface water drains. Both old and new properties need different repair approaches—replacing a high-level cistern in a terrace looks nothing like servicing a macerator in a modern flat.
Toilet repairs in Andover cover cistern replacements (high-level to close-coupled), blockage clearance, macerator servicing and sewer backflow valve installation. We diagnose misconnections in the separate sewer system and handle lead-solder pipe failures common in Victorian properties.
Drainage in Andover — what local engineers know
Andover sits in a High flood risk zone, with the River Test, River Anton and Pillhill Brook nearby. Southern Water serves the area, and Test Valley council manages planning and drainage enforcement. The combination of hard water from Southern Water and the town's age—a significant share of Andover's properties predate 1920—creates recurring problems: limescale buildup in soil pipe joints, salt-glazed clay pipe failures, and root ingress in collapsed drains. Ground-floor and basement properties are especially vulnerable to sewer backflow during heavy rain. Non-return valve installation is essential protection here.
- 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.
