Plumbing Repairs in Andover
The housing stock in Andover is mixed: Victorian and Edwardian properties sit alongside postwar and modern homes, each with different plumbing vulnerabilities. Victorian homes in postcodes like SP10 and SP11 often have lead supply pipes and brass compression fittings that fail over time; newer homes in SP12 and SP13 tend toward plastic push-fit systems. Andover's separate sewer system means misconnections—washing machines plumbed into surface water drains—are a recurring issue that homeowners don't always spot until damage occurs.
Plumbing repairs in Andover (postcodes SP10–SP13) cover leaking pipes, failed fittings, and valve replacement. Victorian homes often have lead supply pipes and failing brass fittings; modern homes typically use plastic push-fit systems. Southern Water's hard water causes limescale buildup across all property types, requiring regular descaling and powerflush maintenance.
Drainage in Andover — what local engineers know
Andover sits in Test Valley Council area and is supplied by Southern Water, which delivers hard water that accelerates limescale buildup in boilers, radiators, and soil pipe joints—a widespread maintenance driver across the town. The River Test, River Anton and Pillhill Brook put Andover in a High flood-risk zone; ground-floor and basement properties are particularly vulnerable to sewer backflow during heavy rain. With the separate sewer system here, misconnections (appliances draining to surface water rather than foul sewers) can trigger environmental enforcement action. The prevalence of pre-1920 stock—salt-glazed clay drains and lead-solder copper pipework—means pipe collapse and root ingress are common failure modes.
- 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.
