Plumbing Emergencies Explained: What Can’t Wait and What to Do First

When something goes wrong with your plumbing, it can be difficult to know whether you’re dealing with a minor inconvenience or a serious issue that needs urgent attention. Plumbing emergencies often require quick decision-making, especially when there’s a risk to safety, property, or essential services. At Newman & Barker Plumbing, we regularly help homeowners and businesses navigate these situations with clear advice and fast, professional support.

As a team that’s been providing plumbing services for more than three decades, including 24/7 emergency call-outs for homes and businesses, we’ve seen it all, from small leaks that can wait until morning to burst pipes and gas leaks that need immediate attention.

In this guide, we explain what actually counts as a plumbing emergency, what can’t wait, and what to do first to protect your home before our licensed plumbers arrive.

What Counts as a Plumbing Emergency?

Every situation is different, but in general, we consider a job an emergency when:

  • There is a risk to safety (people, pets, or property)
  • There is active water or gas damage occurring
  • You have lost a critical service (such as hot water or working toilets)

Understanding the difference between urgent and non-urgent issues helps homeowners respond calmly and appropriately during plumbing emergencies, reducing damage and safety risks.

Some of the most common plumbing emergencies we attend include:

1. Burst or Severely Leaking Pipes

If water is pouring from a pipe, ceiling, wall, or under a sink and you can’t control the flow, this is an emergency.

Left unchecked, burst pipes can:

  • Cause major damage to floors, walls, and electrical systems
  • Lead to mould growth and structural issues
  • Result in extremely high water bills

If this happens, turn off your main water supply (more on that below) and call us straight away.

2. Gas Leaks

Any suspected gas leak is an urgent situation. Common signs include:

  • A strong smell of gas
  • Hissing sounds near gas pipes or appliances
  • Dizziness, nausea, or headaches when gas is in use

Because we’re licensed gas fitters as well as plumbers, we can safely locate and repair gas leaks, assess gas appliances, and ensure everything is returned to a safe standard.

3. Sewage Backups and Overflowing Toilets

If sewage is backing up into your toilet, shower, or floor drains, or if a toilet is overflowing and won’t stop — this should never be left unattended.

Sewage issues can:

  • Create serious health risks
  • Damage to the flooring and internal surfaces
  • Spread quickly through other drains in the home

If possible, shut off water to the affected toilet, avoid using other fixtures, and call a plumber immediately.

4. Major Stormwater or Drainage Failures

After heavy rain, blocked stormwater drains or damaged pipes can cause water to back up around your property.

If water is:

  • Pooling around the house
  • Flooding garages or under-house areas
  • Coming up through external drains

…you’ll want professional help promptly to prevent further damage.

5. Sudden Loss of Hot Water

A complete loss of hot water can be an emergency, particularly for families with young children, elderly residents, or businesses that rely on hot water to operate.

We work on all gas and electric hot water systems and can assess whether the issue requires urgent attention or can be scheduled for the next available appointment.

What Usually Isn’t an Emergency (But Still Needs Attention)

Some plumbing issues are frustrating but don’t always require an after-hours visit. In many cases, booking a standard appointment can save unnecessary costs.

Examples include:

  • Slow-draining sinks or showers that are still functioning
  • Dripping taps that can be isolated
  • Gradually developing low water pressure
  • Running toilets that aren’t overflowing

While these issues should still be repaired, they don’t usually require the immediate response that true plumbing emergencies do.

If you’re unsure, it’s always best to call and ask — we’ll give honest advice about urgency.

What to Do First in a Plumbing Emergency

If you’re facing any of the situations above, taking the right steps early can reduce damage and keep everyone safe while help is on the way.

1. Turn Off the Water Supply

For burst pipes or major leaks, turn off the main water isolation valve. This is usually located:

  • Near the front boundary of the property
  • Inside a meter box or pit
  • Sometimes along a side boundary

If the issue is limited to one fixture, a local isolation valve may be enough.

2. Turn Off Gas (If Applicable)

If you suspect a gas leak:

  • Turn off the gas at the main meter if it’s safe
  • Avoid naked flames and electrical switches
  • Open doors and windows for ventilation
  • Move people and pets away from the area

Then seek professional help immediately.

3. Protect Electricals and Valuables

If water is near power points or appliances:

  • Avoid standing in pooled water
  • Turn off the power at the switchboard if safe
  • Move furniture and valuables out of harm’s way

Never put yourself at risk. Safety comes first.

4. Contain Water Where Possible

Use towels, buckets, or mops to reduce water spread. For sewage issues, avoid direct contact and keep the area isolated.
