Home › Frozen Pipes
Cork winters are soft and wet far more than they're cold — which is exactly the trap. The hard frost that visits once every few years finds every bare pipe in the county on the same morning. Here's how to be the house that was ready.
Tap down to a dribble in freezing weather? Stopcock off as a precaution, open the affected tap, then gentle heat only, from the tap end back — hairdryer on low, warm towels, a heated room. Never a flame, never a blowtorch. Pipe already split? Leave the water off and ring +44 20 4577 2888, any hour, to be connected with a local plumber.
The one about the soft winter
Rarely — and that rarity is the whole problem. Nobody lags for weather that comes once every few years, so when it comes, it collects.
Ask around after any proper cold snap and you'll hear the same story from every direction: the whole road ringing plumbers on the same morning. Not because Cork's frost is fierce, but because it's rare. Where winter mostly means Atlantic rain, the attic pipes go unlagged, the garage run stays bare, and the outside tap keeps its water all year. Then a clear week turns bitter, and every one of those forgotten pipes is suddenly the main character.
The early warning is modest: a tap that slows to a dribble in freezing weather. Catch the story at that chapter and it ends cheaply — which is what the rest of this page is for.
The one about the fiver of foam
Lag the forgotten pipes, find the stopcock, mind the outside tap. An hour of a mild Saturday against a ruined ceiling — no contest.
The pipes that freeze are always the same ones: attic runs above the insulation, garages and sheds, anything clipped along an outside wall, and the outside tap standing charged through the winter. Foam lagging from any hardware shop is the cheapest plumbing work you'll ever do — mind the bends and joints where cheap kits give up early. Isolate and drain the outside tap before winter if there's a valve for it.
Two habits finish the job. First, when a rare freeze is actually forecast, keep the heating ticking over low rather than fully off overnight, crack the attic hatch so house warmth reaches the tank, and open the cupboard doors under sinks on outside walls. Second, know where your stopcock is and prove it turns, tonight, while the floor is dry. The freeze that becomes a flood is stopped at that valve.
The one about the hairdryer
Water off first, then gentle heat from the tap end back. Hairdryer on low, warm towels, patience — and never, ever a flame.
Shut the stopcock before you warm anything, because here's the catch nobody tells you: you can't yet know whether the ice has split the pipe. Frozen water expands and can crack copper without spilling a drop — the plug of ice seals its own damage — and the flood only begins when the plug melts.
Open the tap the frozen run feeds, so meltwater has somewhere to go and you can see your progress. Then work the heat in gently from the tap end back towards the blockage: a hairdryer on its low setting, towels soaked in warm water and wrung out, a hot water bottle laid along the run, or simply heating the room. The rule with no exceptions, worth saying twice: no blowtorch, no naked flame, no fierce heat of any kind. Ice yields to patience; answer it with violence and you'll trade a frozen pipe for a burst one.
The one where the ice already won
The water stays off — full stop. Thawing a split pipe with the mains on is booking the flood in for later.
A bulge in the pipe, a hairline crack, a bead of water appearing at a joint as things warm — any of those means the freeze has already done its damage, and the job changes from thawing to containing. Keep the stopcock closed, open the cold taps to drain what's left in the pipework, and let the plumber make the repair before anything is refilled and put back under mains pressure.
And if the melt has beaten you to it and water is actively escaping, the burst pipes guide walks the first five minutes in the right order: water, pressure, electrics, boiler, phone. Either way, ring with the plain facts — where, how fast, what you've done — and the van arrives half-briefed.
A tap that slows to a dribble or gives nothing at all during freezing weather is the classic opening line — usually first thing in the morning, usually fed by a run through the attic, the garage or an outside wall. A stretch of pipe noticeably colder than the rest, or wearing actual frost, settles the question. If the other taps run grand, the freeze is local to that one run.
No — and that's the one rule of this story with no exceptions. Naked flames and fierce heat near a pipe risk fire, scalding steam and joints letting go all at once. The safe tools are gentle ones: a hairdryer on low, towels soaked in warm water, a hot water bottle, or simply heating the room and letting patience do the work.
On the rare nights a real frost settles over Cork, yes — low and steady overnight is cheaper than a burst pipe by a distance. Open the attic hatch a crack so house warmth reaches the tank and pipes up there, and open the cupboard doors under sinks on outside walls. An empty house in a freeze wants either background heat or the stopcock closed and the system drained.
Then the water stays off — thawing a split pipe with the mains on is just booking the flood in for an hour later. Keep the stopcock closed, open the cold taps to drain the pipework, and ring to be connected with a local plumber before anything is refilled. If water is already escaping, the burst pipes guide walks the first five minutes in order.
