We know you need quick, practical steps when water is running where it shouldn’t. First, locate and shut off the main valve to stop flow and limit further damage. That single action buys vital time and reduces the risk of worsening the issue.
Once flow is stopped, we assess fixtures and drains to find the source. Mop standing water and avoid contact if there’s any chance of electrical hazards. If a safe temporary measure is possible, we apply it; if not, we wait for a licensed professional.

Assess the situation fast and stay safe
A rapid, focused check of fixtures and drains helps us decide the safest next step.
Quickly scan the area to identify the source. Look for dripping or spraying water, damp cabinetry, ceiling stains, hissing pipes, gurgling drains or sewage odours.
Identify the source: leaks, burst pipes, blocked drains or sewage backups
We scan taps, exposed pipes and toilets to separate minor issues from severe ones. Note flow rate, affected rooms and any chance of overnight damage.
Contain water and evaluate severity before taking action
Use towels, buckets and trays to limit spread. Shut the main valve if possible, then mop up and cordon off wet floors to reduce slips and electrical risk.
- Watch for signs such as sudden sprays, rising wastewater or ceiling bulges.
- Photograph visible damage for insurance and to speed up our response.
- Never stand in pooled water; keep children and pets away until safe.

Shut off the water supply to limit damage
The fastest way to protect your home is to isolate the water at its source.
Finding and turning the main valve off in Australian homes and units
The main shut-off is usually at the front boundary near the water meter for freestanding homes. In units, look under sinks, behind toilets or beside appliances for isolation valves.
Turn the valve clockwise until snug to shut water and stop flow. Test by opening a tap to confirm the supply has stopped.
Isolate fixture valves for toilets, sinks and appliances
Where possible, close mini-stop valves to isolate a toilet, sink or washing machine. This keeps the rest of the property on water while you limit damage to the affected area.
For hot water issues, turn off the cold inlet to the hot water unit but be careful to avoid scald risk when testing taps.
Power safety: consider switching off circuits in wet areas
If water is near outlets or appliances, switch the relevant circuit off at the breaker panel. Do not touch wet switches and avoid standing in pooled water.
If a valve is seized or damaged, don’t force it — call us. Our team is available day and night across Melbourne to help when valves fail or urgent isolation is needed. Call OnCall Emergency Plumbers on 1800 571 216.
Spot the hazards: electricity, slips, sewage and gas
Hazards in a wet area can escalate quickly; spotting them early keeps people safe.
We treat standing water as potentially live until circuits are isolated and the area is checked. Avoid touching switches or appliances if floors are wet. Small patches near powerboards can still pose danger.
- Electrical risk: assume water may carry live current and keep everyone clear until power is off.
- PPE: wear non-slip shoes, gloves and eye protection before entering contaminated zones.
- Hidden hazards: murky water can hide sharp debris and chemical residues that increase cut and contamination risk.
- Ventilate and evacuate: open windows and doors for stale odours. If gas or heavy sewage smells persist, leave the area and wait for help.
- Cordon off the area: restrict access to protect people and pets and reduce further damage.
Wash hands and disinfect surfaces after contact with wastewater. Our team arrives equipped to manage contaminated water safely, using quality materials from reputable brands to resolve hazards quickly and affordably. For urgent support in Melbourne, call 1800 571 216—we respond to emergencies and complex issues with experienced plumbers.
Plumbing emergency first aid for burst or leaking pipes
Stopping water, containing the drip and applying a short-term seal buys time for proper repairs.
After the main valve is closed, drain pressure and dry the affected pipe thoroughly. Adhesives and tape will not stick to wet metal, so dry cloth and a quick blow with a towel work best.
Dry, clean and wrap
Apply pipe repair tape or duct tape under tension with several overlapping layers. Cover a few centimetres either side of the leak and press firmly to seal.
Epoxy putty for pinhole leaks
Knead epoxy putty until consistent, press it into the crack and feather the edges. Allow the cure time shown on the product before turning water back on.
Rubber pads and clamps
Place a rubber pad over the split, then fit a clamp to compress the rubber. Tighten evenly — do not over-torque corroded fittings as this can cause further burst or damage.
Containment tactics
- Use a bucket under the drip and lay towels to protect cabinetry and floors.
- Direct steady drips into a drain if safe, and cordon off wet areas to reduce slip risk.
- Never apply open flame, boiling water or heat guns to a pressurised pipe.
These steps are stop-gap only. We use branded, quality materials for permanent repairs. For 24/7 response in Melbourne, call OnCall Emergency Plumbers on 1800 571 216.
| Temporary method | Best for | Time to cure/use |
|---|---|---|
| Pipe repair tape / duct tape | Small splits and weeps | Immediate hold; inspect within 24 hours |
| Epoxy putty | Pinhole leaks and hairline cracks | 15–60 minutes to set, full cure per product |
| Rubber pad + clamp | Short longitudinal splits | Immediate; check tightness regularly |
| Containment (buckets, towels) | Ongoing drips until repair | Use until the pipe section is replaced |
Unblocking drains and toilets without causing damage
Simple techniques often shift stubborn blockages, but careful handling prevents costly damage to pipes and seals.
Start with a good plunger. Seal the outlet, keep the cup covered with water and use steady, controlled strokes. Avoid aggressive jerks that splash contaminated water or dislodge seals.
When to try hot (not boiling) water
Pouring hot (not boiling) water can soften grease and soap scum. Use moderate heat to protect ceramic, rubber seals and joints. Repeat slowly and check for flow between pours.
Baking soda and vinegar for mild clogs
For slow drains, add a cup of baking soda, then a cup of vinegar. Wait 15–30 minutes, then flush with hot water. Stop if bubbling grows intense or fumes form.
- Avoid mixing chemicals—never combine products; fumes and heat can damage pipes.
- Do not force a drain snake; if the cable kinks, stop to avoid puncturing the pipe.
- Pause immediately if the toilet bowl rises or wastewater backs up—this may signal deeper issues.
- Contain splashes with towels, wash hands afterwards and keep children and pets away.
If DIY measures don’t clear the blockage or water rises dangerously, call OnCall Emergency Plumbers Maidstone on 1800 571 216 for fast, affordable help from experienced professionals.
| Method | Best for | Risk |
|---|---|---|
| Plunger | Toilet and sink blockages | Low if used correctly |
| Hot (not boiling) water | Grease and soap build-up | Low when moderate heat used |
| Baking soda + vinegar | Minor slow drains | Moderate; stop if vigorous reaction |
| Drain snake | Deeper obstructions | High if forced or kinked |
Use tools with care to avoid injury and further damage
When tools are in use around water, safe handling is the difference between a minor fix and a major claim.
Handle sharp and heavy items carefully and secure them when not in use. Inspect handles, jaws and cables for cracks or frays before you start.
Gloves, eye protection, and steady handling of wrenches and drain snakes
We recommend basic PPE—gloves and eye protection—before you pick up any wrench, plunger or snake in a wet area. Insert augers slowly to reduce splash and contamination.
Keep your stance stable and use short, controlled movements. That lowers the risk of slips, strain and accidental damage to a pipe or fitting.
What not to do: forcing augers, mixing chemicals, or over-tightening fittings
- Avoid forcing an auger or over-tightening compression nuts; both can crack plastics, crush ferrules or distort soft copper.
- Never mix drain chemicals—if one product was used, stop and call us instead to prevent dangerous reactions.
- Stop DIY if water rises, you hear a sudden crack or a new leak appears elsewhere; these are signs of burst pipes or deeper issues.

FAQ
What should we do immediately when a pipe bursts in our home?
Shut off the main water supply straight away to limit damage, move people away from the wet area and electrical outlets, then use towels and buckets to contain drips. Contact OnCall Emergency Plumbers on 1800 571 216 for rapid professional help if the leak is large or we cannot isolate it ourselves.
How do we find and turn off the main water valve in an Australian house or unit?
The main valve is often near the water meter, under the house, in a meter box on the footpath, or inside a garage or laundry. Turn the valve clockwise to close. If unsure, isolate individual fixture valves (toilets, sinks, washing machines) while we locate the main supply.
Can we safely use tape or clamps as a temporary fix on a leaking pipe?
Yes — pipe repair tape, duct tape, rubber pads and hose clamps can provide a short-term seal to reduce flow. Clean and dry the area first, wrap the tape tightly or compress the pad with a clamp, then call a qualified plumber to perform a permanent repair.
When is it necessary to switch off electrical circuits during a water incident?
If water reaches power points, appliances or electrical switchboards, turn off the circuit at the meter or main switch before entering the wet area. If we cannot access the switch safely, evacuate and call emergency services and our plumber for advice.
What are safe steps to clear a blocked toilet or drain at home?
Start with a plunger using steady, controlled pressure. For sinks and showers, remove visible debris and try a mixture of baking soda and vinegar for mild clogs, followed by hot (not boiling) water. Avoid chemical drain cleaners and do not force a drain snake if resistance is strong — call a professional to prevent damage.
How can we reduce health risks from sewage backups?
Keep people and pets away, ventilate the area, wear gloves and eye protection, and place buckets or containers to contain flow. Disinfect affected surfaces once the water has been contained, and arrange a specialist clean-up and repairs with our team to address the source safely.
What personal protective equipment should we use when attempting a temporary repair?
Use gloves, eye protection and sturdy footwear. A torch helps in dark spaces. Avoid direct contact with contaminated water and never mix chemicals. If the task exposes us to sharp debris, sewage or potential gas odours, we should step back and call professionals.
How effective is epoxy putty for small pipe cracks or pinhole leaks?
Epoxy putty can seal minor cracks temporarily when applied to a clean, dry surface and allowed to cure. It’s a short-term measure to reduce leakage until a qualified tradesperson can replace the damaged section and verify the integrity of the line.
What should our household emergency toolkit include for water incidents?
Keep a plunger, bucket, heavy towels, pipe repair tape, rubber pads and clamps, epoxy putty, adjustable wrench, torch, gloves and eye protection. Also note who in the house will shut off the main valve and who will call OnCall Emergency Plumbers or an approved plumber.
When should we stop DIY attempts and call OnCall Emergency Plumbers on 1800 571 216?
Call us immediately if the leak is large, water affects electrical systems, there’s sewage backflow, the main valve won’t close, or temporary fixes fail. We provide 24/7 assistance across Melbourne to limit damage and carry out safe, permanent repairs.
Are there quick containment tactics to limit water damage until help arrives?
Yes — turn off the water supply, use buckets and towels to catch and soak up water, place waterproof sheeting over furniture, and move valuables to dry areas. We can advise on immediate containment steps over the phone while our technicians are en route.
What not to do when dealing with blocked drains or damaged pipes?
Don’t pour harsh chemicals down the drain, force augers or plungers aggressively, over-tighten fittings or attempt complex repairs without experience. These actions often worsen damage and increase repair costs — call professionals to avoid risk and further issues.
How can we spot early warning signs that a pipe or drain needs attention?
Watch for slow draining, recurring clogs, damp patches, musty odours, unexplained increases in water bills, or minor leaks that reappear. Regular maintenance and prompt attention to these signs reduce the chance of major failures.
Do we need specialised tools to handle minor leaks safely?
Basic tools like an adjustable wrench, plunger, bucket, tape and clamps cover most temporary responses. More complex tasks require drain snakes or power tools handled by trained technicians to avoid injury and further damage.
Will temporary repairs affect future insurance claims?
Temporary, documented efforts to limit damage — such as shutting off supply and using containment measures — typically support insurance claims. Keep photos, notes and receipts, and arrange permanent repairs promptly with a licensed plumber to satisfy policy conditions.
