This customer thinks there is a leak under their kitchen floor.
It's the only logical explanation as to why there is water
coming up through the floor. The water is puddling and making
the grout lines wet.
There is also a faint noise of running water under the kitchen
sink.
First Matt tested the Hot & Cold Feeds from the hot water tank
to the kitchen sink – both held pressure so were confirmed as
not leaking.
The next pressure test is on the mains feed for the drinking
water which confirms a leak.
We then use
Tracer Gas leak detection
which gives inconclusive results.
Then Matt uses an
Acoustic Ground Microphone
to listen for the sound of the leak below the ground.
Matt located the leak to under a single kitchen floor tile –
lifting the tile revealed the leak! The leak was found to be a
small split on a copper pipe which Matt repaired.
