Common plumbing emergencies in Cork homes
If it's one of these, you're not the first — they're the calls we get most. Here's what's usually going on, why it matters, and how we put it right.
Burst pipe
Water spraying or pooling, often with a drop in pressure.
Risk: fast water damage to floors, ceilings and wiring.
Fix: isolate, repair or replace the section, pressure-test.
Leak through the ceiling
A stain spreading, dripping or a bulging ceiling.
Risk: hidden damage and, near light fittings, an electrical hazard.
Fix: trace the source above, repair, then make safe.
Overflowing toilet
The bowl rising instead of draining, or water at the base.
Risk: hygiene and water damage to the floor below.
Fix: stop the supply, clear the blockage or fault, test.
Hot water cylinder leak
Water pooling around the cylinder or in the hot press.
Risk: damage to the press and ceilings, loss of hot water.
Fix: isolate, repair or advise on a replacement cylinder.
Heating or radiator leak
Damp under a radiator, a drip at a valve, or pressure dropping.
Risk: floor damage and a heating system that won't hold pressure.
Fix: isolate the radiator, repair the joint or valve, re-pressurise.
Broken stopcock or valve
A stopcock that won't turn, or one that leaks when you use it.
Risk: you can't shut the water off when you most need to.
Fix: replace the stopcock or isolation valve so you're back in control.
Overflowing attic tank
Water overflowing outside, or dripping through an upstairs ceiling.
Risk: a steady leak into the attic and rooms below.
Fix: sort the ballcock or valve and check the tank.
Sudden loss of water
Taps run dry or pressure collapses with no warning.
Risk: often a hidden burst or a supply fault.
Fix: find the cause, repair, and confirm the supply is restored.
What to do before we arrive
A few simple steps can stop a small flood becoming a big one. Do what you safely can — and don't worry if you can't manage all of it.
Turn the water off
Find your stopcock and turn it clockwise to shut off the mains. It's usually under the kitchen sink, in a utility, or near the front door.
Drain it down
Open the cold taps and flush a toilet to drain the remaining water out of the pipes and away from the leak.
Switch off heating / immersion
If the leak is on a heating pipe or the cylinder, turn off the boiler and the immersion to stop it heating and circulating.
Protect what you can
Move furniture, electricals and anything valuable clear of the water, and lift rugs if it's safe to do so.
Mind the electrics
If water is anywhere near sockets, fittings or the fuse board, keep clear and switch the electricity off at the board only if it's safe to reach.
Catch the water & call
Put down buckets, basins or towels to catch drips, then give us a ring. Skip risky DIY — we'll talk you through anything else on the phone.
Don't know where your stopcock is? Ring us anyway — we can talk you through finding it, or how to limit the damage until we get there. That's exactly what the call is for.

How to avoid the next emergency
Most call-outs aren't bad luck — they're a small problem that went unnoticed. A bit of upkeep saves you the 2am surprise.
Know where your stopcock is and check it turns freely, so you can shut the water off fast if you ever need to. In winter, lag any exposed pipes in the attic or garage — frozen pipes are one of the most common Cork burst calls when a cold snap hits.
Keep an eye out for the early warning signs: damp patches, a drop in pressure, or a boiler that keeps needing topped up. Catching those early is far cheaper than a flood. A yearly boiler service and general plumbing maintenance are the simplest ways to stay ahead of leaks and breakdowns.
If your pipework or cylinder is old and giving trouble, it can be worth planning a replacement on your terms rather than waiting for it to fail — whether that's tired pipework, an ageing cylinder, or a boiler that's due for replacement.
