Push-fit joint under a new kitchen floor
The property
A newly built house with a cold pipe laid in the concrete under the tiles, running from the utility to a sink in the kitchen island.
The problem
The water company's letter said readings showed constant use. The grout round the island looked darker than elsewhere, and the owners doubted a house so new could leak.
How we found it
With the stop tap shut the meter fell still. The island branch then failed a pressure test, and tracer gas surfaced through the grout by its plinth.
The outcome
Lifting two tiles at the mark exposed a push-fit joint that had never fully seated. The repair was priced separately, and the owners then answered the water company's letter.
