## ADI Leak Detection case study 208: underfloor heating leak in Marlborough (SN9 5)

Summary: ADI Leak Detection engineer James Bexter investigated an underfloor heating leak in Marlborough, Wiltshire (SN9 5), using acoustic correlation, pressure testing and visual inspection. Leak location: buried pipework in the corner of the office room. Work done: temporary repair only, as the buried pipework is plastic. Outcome: no warranty on the temporary repair, which the customer understands.

## ADI Leak Detection case study 175: underfloor heating leak in Nottingham (NG17 9)

Summary: ADI Leak Detection engineer Adam Regan investigated an underfloor heating leak in Nottingham, Nottinghamshire (NG17 9), using acoustic correlation, thermal imaging, tracer gas and pressure testing. Leak location: middle of the left side floor, where the thermal camera showed a faint anomaly. Work done: repair carried out by the onsite plumbers.

## ADI Leak Detection case study 101: underfloor heating leak in Battle (TN31 6)

Summary: ADI Leak Detection engineer Grant Corney investigated an underfloor heating leak in Battle, East Sussex (TN31 6), using thermal imaging, a damp meter, pressure testing, an endoscope camera, acoustic listening and leak dye. Leak location: 22mm/22mm/15mm tee on the hot supply. Work done: fitting taken out and replaced with a Hep20 22mm/22mm/15mm tee. Outcome: pressure held on retest with no further current leaks.
