Leak Detection in Andover
Andover's separate sewer system and aging Victorian/Edwardian properties (built 1900–1920) are prone to hidden leaks that go undetected for months. Hard water from Southern Water causes pin-hole corrosion in copper pipework across SP10–SP13—acoustic and thermal imaging can locate these leaks without excavation. Early detection saves money and prevents water damage to your foundation.
Leak detection in Andover uses acoustic loggers and thermal imaging to find hidden leaks without digging. These methods pinpoint pin-hole corrosion in copper pipes and cracks in older clay drains. Your insurer typically covers the detection cost under trace-and-access.
Drainage in Andover — what local engineers know
Andover sits in a High flood risk zone, with the River Test and multiple watercourses nearby. Test Valley Council property records show a significant share of homes were built before 1920, making salt-glazed clay drains and lead-solder copper joints common culprits for failure. Hard water from Southern Water accelerates pin-hole corrosion—especially in radiator and boiler pipework—leading to slow leaks that damage walls and electrical systems. Our acoustic loggers and thermal cameras pinpoint these leaks without disturbing your property, critical in flood-prone areas where foundation moisture threatens structural integrity.
- 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.
Leak Detection prices in Andover
Every Andover job is quoted as a fixed price before work starts — what we quote is what you pay, with no call-out fee for providing the quote. However, the final price depends on access (an external inspection chamber is quicker than internal-only access), the pipe material and condition , and how established the blockage or fault is. Request your free quote and we'll confirm the price and your engineer's ETA in the callback.
In summary, Leak Detection in Andover is backed by a 12-month workmanship guarantee. Furthermore, every job includes a written completion report. Consequently, you have full documentation if the same fault recurs.
