Not every leak announces itself with a flood. Some spend a whole season working quietly behind a wall or under a floor, and the house drops hints long before it shows the damage. This chapter is about hearing those hints early — and the simple test that says whose pipe is talking.
Water near sockets, or a ceiling starting to sag? That is no longer a hidden leak — shut the main stopcock, switch off the electrics at the consumer unit if you can reach it dry-footed, stay out from under any bulge, and ring 020 4577 2888 to be connected with a local plumber, whatever the hour.
The house speaks first in small tokens: a damp patch on a wall or ceiling that was not there last month, a tide-line stain spreading on the plaster below the bathroom, a musty smell in one room that airing never quite shifts, a floorboard that has begun to lift or a skirting gone soft. Listen, too — a faint hiss of running water in a silent house, with every tap closed, is one of the most reliable tells there is. And the boiler keeps its own diary: a sealed system that needs topping up every week is losing water somewhere, and that water is going into the fabric of the house. If your home has a water meter — most in Scotland do not — a reading that creeps while everything is off tells the same story in numbers.
A quiet half hour · The stopcock testOne unhurried test settles most of it, and it costs nothing. Turn off every tap, pause the washing machine and dishwasher, then close the main stopcock. Now watch and listen. If the damp patch stops growing, or the hiss falls silent, the leak sits on your own pipework — somewhere downstream of that valve — and a plumber can trace it from there. If nothing changes, the trouble may be on the supply side, or not be plumbing at all; a slipped slate or a failed gutter seal writes very similar stains on a stone wall. In the minority of homes hereabouts with a meter, add arithmetic: read it, use no water for a solid half hour to an hour, and read it again. A meter that moved on its own has answered the question. Honesty matters here — this test tells you which side of the stopcock the leak is on, not its exact address; the pinpointing is the plumber's craft.
March – April · The thaw's favourite trickAround Elgin the hidden leak has a favourite season, and it is the thaw. A pipe that froze quietly in a January cold snap can split without spilling a drop — the ice seals its own crack — and only when the first mild week arrives does the water find its way out, slowly, behind a wall in the old part of the house or above a bedroom ceiling. That is why the spring walk-through earns its place in the almanac: sniff for new damp, look over the loft, run a hand along pipework in the cold corners, and treat any new stain in March as a message from December. Caught at the stain stage it is a repair; left until the ceiling speaks, it is a redecoration.
Any night · When hiding time is overThree signs promote a leak from the diary to the phone. Water anywhere near sockets, appliances or light fittings — electricity and water hold no negotiations, so the consumer unit goes off if you can reach it dry-footed. A ceiling that sags or bulges, which means water is pooling above the plaster and choosing its moment; stay out from under it. And a patch that spreads while you watch, because that is not seepage but flow. In each case the order of work is the one this almanac always gives: stopcock off, electrics safe, then ring and say plainly what you can see and hear.
Turn off every tap and water-using appliance, then close the main stopcock. If a damp patch stops growing, or a hiss of running water falls silent, the leak is on your own pipework, downstream of that valve. If nothing changes with the stopcock shut, the trouble may be on the supply side, or may not be plumbing at all — rain finding a way in tells a very similar story on a wall.
Very often, yes. A sealed heating system that needs topping up again within days is losing water somewhere — a weeping radiator valve, a joint under a floor, or a fault within the boiler itself. Top up once and watch the gauge; if the needle keeps sinking, stop topping up and have the loss traced, because the escaping water is going somewhere in the house.
Most homes in Scotland are unmetered, so the meter trick is often unavailable — but the stopcock test works in any house, and your senses do the rest. Pick a quiet moment, turn everything off, and listen for hissing at pipework, under floors and at the stopcock itself. Watch suspect patches over days, and check the overflow pipes outside — a steady drip from one is a leak announcing itself.
When water is anywhere near sockets, light fittings or appliances; when a ceiling is sagging or bulging; or when a patch is visibly spreading while you watch. Shut the stopcock, switch off the electrics at the consumer unit if you can reach it without standing in water, stay out from under a bulging ceiling, and ring straight away rather than waiting for morning.
