Quick Answer
Call an emergency plumber immediately for burst pipes, no water to the whole house, sewage backing up into fixtures, gas leaks near plumbing, or water leaking near electrical fittings. Emergency call-out fees in Melbourne range from $150–$350, with total job costs typically $300–$800 for after-hours work. Knowing your mains shutoff location before an emergency happens can limit water damage to minutes rather than hours.
True Plumbing Emergencies: Call Now
These situations require an immediate call to a licensed emergency plumber. Every minute of delay increases damage and cost.
Burst or Fractured Water Pipe
A burst pipe can release 400–1,000 litres of water per hour into your walls, floors, and subfloor. Turn off the mains water immediately at the meter (usually at the front of the property near the boundary), then call an emergency plumber. In Melbourne’s SE suburbs, many homes have polypipe or copper supply lines that are susceptible to corrosion or movement in reactive clay soils.
Complete Loss of Water to the Property
If you’ve confirmed neighbours have water (check South East Water or Melbourne Water outage maps first), sudden total loss of pressure can indicate a main supply pipe failure, a broken backflow preventer, or a burst pressure limiting valve. This is an emergency — a house without water is unlivable.
Sewage Backup into Fixtures
If sewage or grey water is backing up into your toilet, shower, or floor waste, the main drain is blocked or the sewer has collapsed. Sewage in your home is a serious health hazard. Do not use any plumbing until the blockage is cleared. In clay-soil suburbs like Berwick, Pakenham, and Cranbourne, tree root intrusion is a common cause.
Gas Smell Near Plumbing Appliances
If you smell gas near a hot water system, gas cooktop, or gas heater — leave the house immediately, don’t operate any switches or open flames, and call APA Group (1800 427 532) and your gas plumber. Gas fitting in Victoria requires a separate gas licence from a licensed plumber.
Hot Water System Flooding or Active Leak
A tempering valve or pressure relief valve on a hot water system that’s actively releasing water (not the normal pressure bleed when heating) can indicate dangerous pressure buildup. This is an emergency — call a plumber and do not use hot water until inspected.
Urgent but Not Immediate: Book Within 24–48 Hours
These issues need attention quickly but can wait for a standard booking:
| Issue | Urgency | Why It Can Wait Briefly |
|---|---|---|
| Blocked toilet (one toilet, others working) | 24 hours | Can use other bathroom while waiting |
| Slow-draining sink or shower | 48–72 hours | Can DIY with drain snake or caustic cleaner |
| Dripping tap | 1 week | Wastes water but rarely causes damage; DIY-able |
| Running toilet (not overflowing) | 3–5 days | Costs money on water bill; can DIY flush valve |
| Hot water not heating | 24–48 hours | Inconvenient but not dangerous; check pilot light first |
| Low water pressure (single tap) | 1 week | Often an aerator blockage — clean or replace the aerator |

What to Do While Waiting for the Plumber
- Turn off the mains water. The meter box is usually at the front boundary. A standard 25mm mains shutoff valve needs a flathead screwdriver or water meter key (available at hardware stores for $10–$15).
- Turn off the hot water system. This is especially important for storage systems — without cold water flowing in, continuing to heat can damage the unit. The isolating valve is on the cold water inlet pipe to the HWS.
- Move valuables away from water. Pull furniture, electronics, and documents away from wet areas. Use towels to contain water movement.
- Photograph the damage. Take photos and video immediately — this is important for insurance claims.
- Call your insurer’s 24hr line. Most home insurance policies cover sudden and accidental water damage. Many have approved plumber networks — call the insurer first to avoid jeopardising the claim.
- Don’t use electrical appliances near the water. Even if the power is still on, don’t use anything electrical in a wet area until an electrician has cleared it as safe.

Frequently Asked Questions
What counts as a plumbing emergency in Melbourne?
Any plumbing fault that poses an immediate risk to health, property, or safety. This includes burst pipes actively flooding, sewage in the home, gas leaks near appliances, and complete loss of water to the property. A dripping tap or slow drain is urgent but not an emergency.
How do I find my mains water shutoff in Melbourne?
The main shutoff is at your water meter, usually at the front boundary of the property in a small concrete pit under a lid marked “Water” or “W”. You’ll need a flathead screwdriver or a standard water meter key to open it. In older Melbourne suburbs, meters may be set further back from the road — check along the driveway edge if you can’t find it at the boundary.
Will home insurance cover emergency plumbing in Melbourne?
Most home building insurance policies cover sudden and accidental water damage from burst pipes. They typically don’t cover the cost of repairing the pipe itself — only the resultant damage (water-damaged floors, walls, plasterboard). Read your policy’s “gradual damage” exclusion — leaks that developed slowly over time are usually not covered. Call your insurer before authorising major repair work.
Can I unblock a drain myself to avoid an emergency plumber call?
Yes, for minor blockages. A plunger on a toilet or a 3–5m drain snake on a sink can clear simple blockages without a plumber. For main drain blockages where multiple fixtures are affected, or where you suspect tree root intrusion, you need a licensed plumber with a jet blaster and CCTV — DIY tools won’t reach or clear these.
Why is my emergency plumber so expensive after hours?
After-hours rates in Melbourne typically include a call-out fee ($150–$350), an after-hours labour rate (often 1.5x normal), and minimum charge periods (usually 1 hour minimum). An emergency plumber called out at 11pm on a Sunday can legitimately charge $400–$600 before they’ve fixed anything. The best way to reduce this is to know your shutoff locations so you can stop damage immediately while waiting for a business-hours call.
