Leak Detection in Fleet
Fleet's Thames Water hard water supply accelerates corrosion in copper piping — particularly in Victorian and Edwardian properties where original copper runs are 100+ years old. Pinhole leaks develop silently inside walls, under floors, and beneath gardens, causing water loss, damp, and structural damage before visible symptoms appear. Leak detection technology in Fleet finds these defects without excavation.
Leak detection in Fleet uses acoustic sensors and thermal imaging to locate hidden pinhole leaks in copper pipes without excavation. Hard water corrosion is the primary cause — early detection prevents water loss and structural damp.
Drainage in Fleet — what local engineers know
Thames Water classifies Fleet in a hard water zone — mineral-rich supply that deposits limescale and causes electrochemical corrosion (pitting) in copper pipe joints. Postcodes GU51, GU52, and GU53 contain high concentrations of Victorian stock where original copper is now extremely thin at weak points. Hard water-induced pinholes account for roughly 40% of internal leak investigations in Fleet. Early detection preserves water pressure, prevents secondary damp damage, and avoids the cost of emergency re-plumbing. Hart Council's high flood risk rating means even small internal leaks can contribute to damp conditions that trigger mould and structural deterioration during the town's wet seasons.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Fleet
- Separate sewer system across most of Fleet: misconnections (e.g. washing machines plumbed into surface water drains) are a known local issue and can result in environmental enforcement action
- High flood risk in Fleet: basement and ground-floor properties near watercourses are vulnerable to sewer backflow — non-return valve installation is strongly recommended
- With 34% 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.
