What to Do in a Plumbing Emergency (Before Your Plumber Arrives)

A burst pipe at 11pm. Sewage backing up through the floor waste. The hot water system dumping water across the laundry floor. When a plumbing emergency hits, the first 10 minutes matter.

What you do before your plumber arrives can be the difference between a contained problem and thousands of dollars in water damage. Most of it comes down to shutting off the right valve and knowing what not to touch.

Here's the step-by-step process.

Step 1: Shut Off Your Water

The single most important thing you can do in any plumbing emergency is stop the water flow.

Where to find your mains shutoff valve: In most Northern Rivers homes, the main water shutoff is located at the front of the property near the water meter, usually in a plastic or concrete meter box at ground level near the street boundary. The valve is a lever or gate valve on the pipe coming out of the meter. Turn it clockwise (or move the lever perpendicular to the pipe) to shut off all water supply to the house.

If you can isolate the problem instead: Many fixtures have individual isolation valves. Taps have small valves underneath the basin. Toilets have a valve on the wall behind the cistern. Hot water systems have a valve on the cold water inlet. If the emergency is limited to one fixture and you can see the isolation valve, turn it off there instead of shutting down the whole house.

For hot water system failures: If your hot water system is leaking or has burst, shut off both the water isolation valve on the unit AND the power supply. For electric systems, switch off the circuit at the switchboard. For gas systems, turn off the gas valve on the supply line to the unit.

Tip: If you've never located your mains shutoff before, do it now while there's no emergency. Walk outside, find the meter box, identify the valve, and make sure it turns. Valves that haven't been used in years can seize up. Finding this out during a flood is not the time.

Step 2: Turn Off the Power if Water Is Near Electrics

Water and electricity together create a serious safety risk. If water is spreading across floors, pooling near power points, or has reached the switchboard area, turn off the power at the main circuit breaker.

Do not step into standing water to reach the switchboard. If you can't safely access the breaker, call your emergency electrician or Essential Energy (the Northern Rivers electricity distributor) on 13 20 80.

Step 3: Assess and Contain the Damage

Once the water is off and the area is safe, focus on limiting damage.

Move valuables and electronics away from the affected area. Water damage to personal items, electronics, and timber floors happens fast in the Northern Rivers humidity. Mould can begin forming within 24 to 48 hours in subtropical conditions.

Mop up standing water. Use towels, mops, or a wet vacuum. The faster you remove standing water from timber or carpet, the less damage it causes.

Open windows and doors to start airflow. This helps slow mould growth, especially in the warmer months.

Take photos of the damage. Your insurer will need documentation if you make a claim.

Do not attempt to fix pipes, gas lines, or hot water systems yourself. Plumbing work in NSW must be carried out by a licensed plumber. Attempting DIY repairs on gas lines is illegal and dangerous. Temporary patches on water pipes often fail and can cause more damage when they let go.

What Counts as a Plumbing Emergency?

Not every plumbing problem needs an after-hours callout. Knowing the difference helps you avoid unnecessary emergency fees and ensures genuine emergencies get the priority they need.

Call an emergency plumber now if:

• A pipe has burst and water is flooding your home or property.

• Sewage is backing up through floor wastes, toilets, or drains.

• You can smell gas inside your home. Evacuate immediately, do not use any electrical switches, and call your gas supplier's emergency line first, then a licensed gas plumber.

• Your hot water system has burst and is actively leaking.

• A major water leak is causing structural damage or electrical risk.

• You have no water supply to the property and the mains valve is open (the issue may be with the supply, not your plumbing; check with Rous County Council first on 02 6621 8055).

Can wait until business hours:

• A dripping tap or slow leak that can be contained with a bucket or towel.

• A single slow-draining sink or shower (not sewage backup).

• A toilet that runs continuously but still flushes and drains.

• Low water pressure that isn't caused by a leak.

• A hot water system that produces lukewarm water but isn't leaking.

If you're unsure, call JF Plumbing and describe the situation. Jesse will tell you straight whether it needs immediate attention or can wait.

What to Expect When JF Plumbing Arrives

On-site assessment: Once on-site, Jesse assesses the problem, identifies the cause, and explains what needs to happen. You'll get a clear explanation before any work starts, including what it will cost.

Repair: JF Plumbing's vehicle is stocked with the parts and equipment needed for most common emergencies, including burst pipes, blocked drains, hot water system failures, and gas leaks. Most emergency jobs are resolved in a single visit.

Follow-up: If the emergency reveals a larger underlying issue (for example, a burst pipe caused by root intrusion through an aging sewer line), Jesse will outline the next steps and provide a quote for the follow-up work separately.

How to Prepare for a Plumbing Emergency Before It Happens

The best time to deal with a plumbing emergency is before it starts. Five minutes of preparation now saves you stress and damage later.

Locate your mains water shutoff and test it. If the valve is stiff, apply a small amount of lubricant and work it gently until it moves freely.

Know where your switchboard is and which circuits control wet areas (bathrooms, laundry, kitchen, hot water system).

Label your hot water system's isolation valves. Most homeowners have never looked at their hot water unit until the day it fails.

Save your plumber's number in your phone. When a pipe bursts at midnight, you don't want to be Googling. JF Plumbing: 0412 230 635.

Book a preventative plumbing inspection. Properties in the Northern Rivers, especially older homes and coastal properties in Lennox Head and Ballina, benefit from periodic inspections that catch small issues before they become emergencies. JF Plumbing's leak detection service can find hidden problems before they turn into floods.

Frequently Asked Questions

What should I do first in a plumbing emergency? Shut off the water supply. If the problem is isolated to one fixture, close its isolation valve. If it's a major leak or burst pipe, turn off the mains at the water meter, usually located in a meter box at the front of your property. If water is near electrical outlets, turn off the power at the switchboard.

How much does an emergency plumber cost in Australia? Emergency plumbing rates are higher than standard hours, with call-out fees typically ranging from $150 to $300 and hourly rates from $150 to $350. JF Plumbing provides upfront pricing when you call, so you know the cost before committing. Most emergency jobs are resolved in one visit.

Is a blocked drain a plumbing emergency? It depends. If sewage is backing up into your home through floor wastes or toilets, that's an emergency. A single slow-draining sink that isn't overflowing can wait until business hours. If multiple drains are backing up at the same time, the main sewer line is likely blocked and needs prompt attention.

Who is responsible for plumbing emergencies in a rental property in NSW? The landlord (or property manager) is responsible for organising and paying for emergency plumbing repairs. As a tenant, you should take immediate steps to prevent damage (shutting off water) and contact your property manager straight away. If you can't reach them during an after-hours emergency, you're generally within your rights to arrange an emergency repair and notify the landlord afterwards.
