Finding a hot-return leak in an occupied care home.
Visited March 2025
Water was passing through the floor and cavity wall into the plant room. ADI’s investigation had to account for a busy care home where hot water was still in use.

A hotspot beside a covered hatch
Visual inspection and a thermal camera helped trace the pipe layout and locate a hotspot near a covered inspection hatch. Pressure testing was not possible while the hot-water system remained in use.
Working with the caretaker, the engineer removed laminate and screed to open the hatch. This exposed a leaking 28 mm copper hot-return pipe.
The repair and the check
The hot-water circuit was drained, the affected pipework was repaired and re-piped, and the supply was restored. The engineer then made a visual check. This was not a pressure-test pass or confirmation that the entire system was free of other leaks.
Floor repair still to arrange
Opening the hatch disturbed the flooring. The caretaker was to arrange its repair, and the report recommended keeping the inspection access available for future maintenance.
