Not every plumbing issue is an emergency — but some definitely are. Knowing the difference can save you thousands in water damage and repair costs. Here are five warning signs that mean you should call an emergency plumber immediately.
1. Burst or Leaking Pipes
A burst pipe is the most obvious plumbing emergency. If you can see water spraying or flowing from a pipe, turn off your mains water supply immediately and call a plumber. Even a small leak that's spraying under pressure can cause significant structural damage within minutes.
Signs of a hidden burst pipe include unexplained wet patches on walls or ceilings, a sudden drop in water pressure, or your water meter spinning when no taps are on. Don't wait for the leak to get worse — hidden leaks cause mould growth and can compromise your home's structural integrity.
2. Sewage Backup or Overflow
If sewage is backing up through your drains, toilets, or floor wastes, this is a health hazard that requires immediate attention. Raw sewage contains harmful bacteria and pathogens that pose serious risks to your family's health.
Warning signs include multiple drains blocking simultaneously, gurgling sounds when you flush the toilet, and foul odours coming from your drains. A sewage backup usually indicates a blockage in your main sewer line, which needs professional equipment to clear.
3. No Hot Water in Winter
While losing hot water in summer might be inconvenient, losing it in the middle of winter is a genuine emergency — especially if you have young children or elderly family members at home. A failed hot water system in cold weather needs urgent attention.
Before calling, check the obvious: has the pilot light gone out on a gas system? Has a circuit breaker tripped for an electric system? If these quick checks don't resolve the issue, you need a licensed plumber to diagnose and repair the fault.
4. Gas Leak Smell
If you can smell gas (a distinctive rotten egg odour) inside or outside your home, this is a life-threatening emergency. Natural gas is highly flammable and can cause explosions in enclosed spaces.
Immediate steps:
- Do not turn any electrical switches on or off
- Do not use your phone inside the house
- Open doors and windows if safe to do so
- Turn off the gas supply at the meter if you can access it safely
- Evacuate the property and call your gas provider's emergency line, then call a licensed gas fitter
5. Overflowing Toilet That Won't Stop
A toilet that overflows once can usually be fixed with a plunger. But if your toilet is continuously overflowing and won't stop, or if sewage water is coming up through the bowl, you have a serious problem that needs professional help.
Turn off the water supply to the toilet using the isolation valve (usually located on the wall behind the toilet) and call a plumber. Continuous overflow often indicates a blockage further down the line that a plunger can't reach.
What to Do While You Wait
While waiting for your emergency plumber to arrive, take these steps to minimise damage:
- Turn off your mains water supply if there's an active leak
- Move valuables and electronics away from affected areas
- Use towels or buckets to contain water where possible
- Take photos for your insurance claim
- Do not attempt DIY repairs on gas lines — ever
