Home › Hidden leaks
Hidden leaks announce themselves quietly — a stain, a smell, a gauge that will not hold. Here is how to read the signs, run the one honest test, and know when quiet stops being safe.
The short version: damp patches, ceiling stains, a musty smell, a hiss with everything off, or boiler pressure that keeps dropping all point the same way. Turn everything off, close the stopcock, and watch: if the signs stop, the leak is on your own pipework. Spreading fast or near electrics?

No single clue proves it, but two or three together build a case. Walk the house and tick what you find:
This is the one honest test you can run without tools, and it answers the most useful question first: is the leak on your pipework at all?
In Banbridge's older mill-era terraces, pipework of very different ages often shares the same walls — a stain can sit a surprising distance from the leak that feeds it, so resist the urge to open the wall at the stain.
A slow weep can wait for a daytime visit. These three cannot:
Leak tracing is detective work, and your observations are the case file. Have these ready when the phone rings back:
Quite often, yes. A sealed heating system that needs topping up every few days or weeks is losing water somewhere — a weeping radiator valve, a joint under a floor, or occasionally the boiler itself. Stop treating the top-up as the fix and have the loss traced; quiet pressure drop is one of the politest warnings a hidden leak ever gives.
Only if your usage is metered — and most homes in Northern Ireland are not, so an unexplained bill jump is a clue you may simply never get. That makes the physical signs matter more here: damp patches, musty smells, the hiss of water when everything is off, and boiler pressure that will not hold. If your home does have a water meter, the read-wait-read version of the stopcock test is worth doing.
First rule out the innocent explanations: a toilet cistern refilling because its flush valve is letting by, or a washing machine or dishwasher mid-cycle. If every appliance is idle, every tap is closed and the hiss continues, water is moving where it should not be — run the stopcock test, and if closing the stopcock silences the sound, the leak is on your own pipework.
If the patch is spreading, the ceiling is bulging, or water is anywhere near electrics — yes, stopcock off and keep it off. If the leak is slow and stable, you can keep the water on for normal life, but note how fast the signs change so you can describe the pattern. Either way, knowing where your stopcock is before the visit saves real time.
