## ADI Leak Detection case study 47: hot water system leak in Kingston upon Hull (HU9 3)

Summary: ADI Leak Detection engineer Brett Steele investigated a hot water system leak in Kingston upon Hull, East Riding of Yorkshire (HU9 3), using acoustic correlation, thermal imaging, tracer gas, a damp meter, pressure testing and flow metering. Leak location: compression elbow beneath the sink unit. Work done: both leak sections removed and the hot supply re-piped. Outcome: pressure test proved no further issues on the hot supply.
