Every emergency plumbing website tells you to call immediately, about everything, always. Of course they do — emergency call-outs are the product. This guide does something slightly unusual for the genre: it tells you when not to call, because the honest triage is also the correct marketing for the operator confident enough to publish it.
Below is the actual framework our dispatch desk uses to sort 2am form submissions, adapted for the person standing in a Melbourne hallway wondering how bad this is.
Call right now, any hour: the true emergencies
Water you cannot stop. A burst pipe, a failed flexi hose, a split hot water tank — anything flowing that doesn’t respond to turning off a tap. At Melbourne mains pressure a failed braided hose pushes 1,000-1,500 litres an hour into your home; in an apartment, the flat below is collecting within twenty minutes. First move is never the phone: it’s the isolation valve at your water meter (front boundary box for houses, meter cupboard for most flats). Water off, then call. The repair can wait an hour once the flow is stopped; the damage can’t wait five minutes while you search for a phone number.
Sewage coming up. A toilet, shower base or floor waste backing up with wastewater is a health issue, not a convenience issue — and it never improves on its own, because whatever blocked the line is still there while the household keeps adding to it. Stop using water fixtures entirely and call. This is one case where “wait and see” actively makes the situation worse.
Any gas smell. Not us first — 132 771 first, Victoria’s 24/7 gas emergency line. No switches, no flames, ventilate on your way out, everyone outside, call from the street. The distributor makes the supply safe for free; the licensed gasfitting repair and compliance certificate come after. Gas is the one category where over-reacting has no downside and under-reacting can be fatal.
Ceiling bulging with water. A sagging or dripping ceiling below a bathroom or roof space is holding water and deciding whether to fail. Don’t poke it (people genuinely do). Water off at the meter, electricity off to that circuit, call.
Call today, but 8am is fine: the urgent-not-emergency tier
No hot water — in most households. Uncomfortable, urgent, worth same-day service; not worth a 3am dispatch unless the unit is actively leaking from the tank body. The exception is vulnerable households — young children, elderly members, medical needs — where a Melbourne winter without hot water crosses into genuine emergency, and we treat it accordingly.
One blocked fixture with alternatives. A blocked ensuite toilet when the main bathroom works, a slow kitchen sink, a single sluggish shower. Book it, don’t dispatch it. But note the multiplication rule: several fixtures misbehaving at once is a mainline problem — gurgling toilet plus slow shower plus smelly floor waste means the sewer branch itself, and that escalates to the emergency tier before it becomes sewage-coming-up.
The running toilet and the dripping tap. The most profitable fixtures in Melbourne for water retailers. A constantly running toilet can waste hundreds of litres a day. Neither will hurt your house tonight; both are cheap business-hours fixes that pay for themselves.
The Melbourne-specific tells worth knowing
A few local patterns change the maths of “how bad is this”:
- In post-2000 apartments — Southbank, Docklands, the Collingwood and Brunswick in-fill — treat any dampness under a sink or vanity as a pre-echo of a flexi hose failure. Those hoses fail suddenly, at full pressure, in batches by building age. Damp braiding today is a burst at 4am on a long weekend.
- In heritage homes — Albert Park, East Melbourne, the Collingwood cottage rows — a “small” leak in original galvanised pipework is rarely isolated. The pipe that pinholed is the same age everywhere else in the wall. Worth a proper look rather than a patch-and-forget.
- West of the river, a wet winter is a leading indicator: the basalt clay’s swell-and-shrink cycle cracks buried sewers, and the blockage surge follows a few months later. A Maribyrnong drain that gurgles in spring is asking for a camera inspection before it’s a Christmas Day emergency.
- Along the bay, external plumbing ages roughly twice as fast. If your St Kilda or Port Melbourne hot water unit is ten years old and the cladding is showing rust, plan its replacement — don’t wait for the cold-shower morning.
The rule of thumb
If it’s flowing, filling, or you can smell gas — emergency, any hour, and with us the hour doesn’t change the rate. If it’s dripping, draining slowly, or merely dead — it’s a booking, and booking it promptly is what keeps it out of the first category. When you genuinely can’t tell, submit the form and say so: honest triage is the dispatcher’s whole job, and “this can actually wait until morning, here’s a slot” is an answer we give out several times a week.
