Burst Pipe, Sewage Backflow & Fire Investigation Services​

Independent forensic investigation – pipe bursts, sewage backflow, and fire incidents. Liability determination, loss quantification, and claim support for homeowners, landlords, management companies, and insurers.

✅ Scope of Liability Determination (Burst Pipe / Sewage Backflow / Fire)

- Burst pipes: distinguish between age-related failure, excessive water pressure, construction defects, human damage, or inadequate maintenance.

- Sewage backflow: identify blockage or silting of common drainage mains / manholes; intrusion of cement slurry or construction debris into common drains during rooftop works or renovations; cross-connection or improper alterations by multiple units; failed check valves or vent pipes.

- Fire origin: determine short circuits, faulty wiring modifications, kitchen appliance misuse, negligence, or arson.

- Output: clear opinion on who bears responsibility, which party can be pursued for recovery, and whether insurance coverage applies.

✅ Core Investigation Areas

• Burst pipe cause analysis: identify ageing fractures, construction defects, human damage, or management negligence.

• Sewage backflow tracing: inspect common drainage / soil stacks, manholes, podium slabs, and external wall pipes for blockages; check whether rooftop works or renovation debris (cement slurry, stone chips, waste) entered common drains; assess multi-unit connections, check valves, and vent pipe condition; collect water samples for chemical analysis (salinity, ammonia/urea) to distinguish fresh water, salt water, sewage, or toilet return flow.

• Fire origin identification: residue analysis, circuit reconstruction, and burn pattern examination to determine electrical faults, improper modifications, kitchen violations, or intentional ignition.

• Loss quantification: calculate repair costs for floor screeds, false ceilings, timber doors, wardrobes, electronic locks, electrical systems, and contents damaged by clean water or sewage; post-fire structural, finishing, and equipment restoration costs for insurance claims.

• Prevention & liability assessment: inspect building fire services, water supply and drainage maintenance records to clarify legal duties of the owners' corporation, management company, or individual owners.

🔍Advanced Technical Support

- Water pressure testing: simulate peak pressure to verify whether burst was caused by overload or material defect.

- CCTV drain inspection: examine common drainage mains, podium and external wall pipes for blockages, cracks, and misconnections; record location and severity.

- Dye / ball / high-pressure jet testing: trace backflow paths and return points to distinguish private pipes from common mains.

- Infrared thermography + conductive moisture metering: locate hidden water beneath floor screeds, false ceilings, and wall finishes; differentiate new from old leaks.

- Water sample laboratory analysis: salinity, ammonia/urea, turbidity, and pH to classify water source (fresh, salt, sewage, or toilet effluent).

- Concealed leak tracking: combine infrared, moisture readings, and sounding tests to detect hairline cracks and prevent secondary backflow.

- Fire debris / electrical forensics: metallurgical fatigue testing of short-circuited conductors, melt mark comparison, MCB / distribution board data reconstruction.

⚖️Legal Application & Claim Support

- Court‑admissible reports: full evidence chain covering cause, liability ratio, and quantified loss; directly usable in the District Court, Small Claims Tribunal, or Lands Tribunal.

- Insurance negotiation: counter insurer rejection grounds with independent scientific data to secure full payout.

- Expert witness attendance: chartered surveyors, fire engineers, and water specialists appear in court to reinforce your case.

- Sewage backflow specific: where common drainage defects are identified, reports support parallel action under the BD Drainage Repair Notice or FEHD Nuisance Seepage procedure; if poor maintenance, missing drain-clearing records, or contractor negligence is found, assist owners in pursuing the owners' corporation, management company, or responsible contractor.

🚨 Emergency Response Plan

- 24/7 site attendance: priority response for active pipe bursts, ongoing backflow, or dripping sewage from false ceilings; immediate photo/video documentation of floor traps, manholes, rooftop works, and blockage materials; collect water samples before cleanup.

- Interim damage control: advise shutting down affected bathrooms/toilets, setting up absorbent barriers, and isolating power circuits near flooded areas to prevent contamination spread and electric shock risk.

- Cross-agency coordination: cross‑reference Fire Services attendance records, Water Supplies Department / BD drainage plans, and management company maintenance logs to strengthen evidence.

📊 Success Case Highlights

- Pipe Burst Dispute: Confirmed corroded water tank as cause within 3 days, securing HKD 1M+ compensation for owners.

- Sewage Backflow Case:​ The owner was notified that water was accumulating outside their villa unit. The kitchen and bathroom floors, as well as the communal staircase, were flooded. Rooftop floor screeding works were underway at the time. Using multiple detection methods, we concluded that construction debris from the rooftop works had entered the common drainpipe, causing a blockage that led to sewage/wastewater backflow through the floor trap. This was not due to private pipes or waterproofing failure within the unit. Silver Surveyors assessed the repair, demolition, and protection costs at approximately HK$25,200.16, and issued an independent report for the owner to pursue repairs and claims against the contractor / responsible party.

- Sewage Backflow Case:​ The owner experienced sewage backflow in multiple areas including the bathroom, kitchen, and living/dining room. Using various detection methods, we confirmed that the backflow resulted from a common soil stack serving multiple units, not from any single private alteration. The cause was blockage or improper connection of the public drainage system, placing responsibility on the owners' corporation / management company and their duty to maintain common drains. Silver Surveyors assessed the costs for deep cleaning, disinfection, replacement of timber doors, main entrance with digital lock, wardrobe, carpet, etc., at approximately HK$69,588.12. The owner subsequently relied on our expert report to win the case in court and recover the full amount of loss.

- Sewage Backflow Case:​ The owner experienced continuous sewage seepage from the ceiling in the basement. Using multiple detection methods, we confirmed that the sewage backflow originated from the common pipe duct of the building, spreading through the ceilings of bathroom 1 and bathroom 2 to the rooms and corridor. This was not caused by any individual tap or waterproofing failure within the unit. Silver Surveyors assessed the costs for false ceiling, tiling, timber doors, electrical inspection, replacement of smart toilet / bathtub / shower screen, demolition, and cleaning at approximately HK$102,427.67. The owner subsequently relied on our expert report to win the case in court and recover the full amount of loss.

- Restaurant Fire: Exposed illegal kitchen wiring, overturning insurer's denial.

- Industrial Building Leakage: Traced fault to upstairs cooling pipe aging, ending 5-year legal battle.
