You've called an emergency plumber and they're on their way. The next 30–90 minutes — while you wait — can make a significant difference to the final cost and disruption of a plumbing emergency. The right immediate actions limit water damage, protect your family's safety, and make your plumber's job easier and faster when they arrive. Here's exactly what to do for each type of plumbing emergency.

For Any Plumbing Emergency: Know Where Your Shutoffs Are

Before any emergency happens, every household member should know where the main water shutoff is. In Newcastle homes, this is typically:

  • The water meter — usually located near the front of the property, often near the street boundary. A handle or tap valve that turns perpendicular to the pipe stops all water supply to the property.
  • Isolation valves — most modern fixtures (toilets, hot water systems, basin mixers) have individual isolation valves nearby. These allow you to isolate a single fixture without cutting water to the whole house.

Take 5 minutes now to locate these on your property — before an emergency happens. In a real emergency, not knowing where the shutoff is costs critical minutes.

Burst Pipe

  1. Turn off the main water supply immediately at the meter. Every second the water runs, it's damaging your home.
  2. Turn off the hot water system — if the system continues heating with no cold water supply, it can damage itself.
  3. Turn off electricity to any affected areas — water and electricity are a fatal combination. If water is near electrical outlets, light fittings or the switchboard, switch off the relevant circuit breakers.
  4. Move valuables, electronics, and electrical items away from the affected area.
  5. Mop, soak, or bucket excess water where possible to limit spread. Towels and buckets contain but don't eliminate damage.
  6. Open windows and doors to begin drying the space.
  7. Don't turn the water back on until the plumber has repaired the break.

Sewage Backup

  1. Stop using all water immediately — every toilet flush, running tap or washing machine adds to the backed-up volume and increases overflow risk. This is the most important step.
  2. Don't flush any toilet — if the main sewer is blocked, flushing risks sewage overflow onto your floor.
  3. Keep children and pets well away from any area where sewage has backed up. Raw sewage is a serious health hazard containing pathogenic bacteria.
  4. Don't attempt to clear it yourself — plunging or using chemicals in a sewer backup situation spreads contamination and can make the plumber's job harder.
  5. Open windows in affected areas to ventilate sewer gases.
  6. Place old towels around any overflow area to contain spread if safe to do so without exposure.

Gas Leak

  1. Don't turn any electrical switches on or off — light switches, appliances, anything. Electrical arcing can ignite accumulated gas.
  2. Don't use your phone inside — exit the building first, then call.
  3. Extinguish all naked flames — candles, pilot lights.
  4. Leave doors and windows open as you exit to ventilate.
  5. Turn off gas at the meter (outside the property) if you can do so safely without going through gas-contaminated areas.
  6. Evacuate everyone and wait outside well away from the building.
  7. Don't re-enter until the plumber or gas fitter has confirmed it's safe.

Blocked Drain with Overflow

  1. Stop using all water that goes to the affected drain — this prevents further overflow.
  2. If it's a main sewer backup, stop using all water in the house (see sewage backup steps above).
  3. If it's an isolated overflow (single sink, toilet), use alternative fixtures if available.
  4. Don't pour chemicals down blocked drains — this doesn't help and creates a hazard for your plumber.
  5. Place towels or buckets around any overflow to contain water damage to flooring and cabinets.

No Hot Water

No hot water is rarely immediately dangerous, but there are a couple of safety checks:

  1. Don't attempt to relight a gas pilot light if you can smell gas near the unit — evacuate and call immediately.
  2. Don't reset a tripped circuit breaker repeatedly — one reset is fine. If it trips again, leave it tripped and call us. Repeatedly resetting a tripping breaker is a fire risk.
  3. Check if the pressure relief valve is actively discharging — a PRV flowing significant water is a safety issue requiring immediate attention.

Information to Have Ready for the Plumber

When the plumber arrives, having this information ready speeds diagnosis and repair:

  • What symptoms appeared first and when
  • Whether any water shutoffs have been turned off and which ones
  • Whether any chemicals have been poured into drains
  • The age of the property and any known plumbing history
  • Access to relevant areas — keys to locked gates, moving furniture if needed

Should I take photos or video during a plumbing emergency in Newcastle?

+

Yes — after ensuring safety, documentation is valuable. Photograph and video the damage before cleaning up, including water levels, affected areas and any visible pipe damage. This documentation supports insurance claims. However, don't prioritise documentation over safety — address immediate hazards first, document second.

If I've shut off the water, do I still need an emergency plumber to come at night?

+

For a burst pipe: yes, you need it fixed before water can be restored. For a blocked drain: if you've stopped all water use and there's no active overflow, you can potentially wait until morning at standard rates — which may save significant after-hours premium costs. Call us and describe the situation — we'll give you honest advice on whether same-night attendance is necessary or whether it can safely wait for morning.
