Panic wastes the minutes that matter most. A fixed sequence helps because you do not have to think; you just move to the next step. This post walks through the first five minutes of a household plumbing emergency. It complements the emergency guide, which covers specific situations in more detail.
Minute one: is anyone in danger?
Look before you act. Is there a gas smell? Is water reaching power points, appliances or light fittings? Is anyone hurt or at risk of slipping, scalding or being cut? If there is fire, a gas escape or danger to life, leave and call 000. Nothing else on the list outranks this.
Minute two: stop the water
Go to the mains isolation valve and close it fully. If you do not know where it is, this is the moment you find out, so take a minute after the emergency to photograph it. If the leak is at a single fixture, a small isolation tap under the basin or behind the toilet may be enough. In an apartment, the unit may have its own valve, but a riser fault may need the building manager.
Minute three: power and heat
- Keep electricity away from water. If the switchboard is dry and you can reach it without standing in water, switch off circuits to the affected area. If you cannot, stay clear and call 000.
- Protect the hot water unit. With the water shut off, switch off power to an electric unit, or turn gas off at the unit if it is safe. Never let an electric element run in an empty tank.
Minute four: contain and drain
Open the lowest cold tap to relieve pressure and drain what is left in the pipes. Use towels, buckets and a mop to slow spreading water, and move rugs, electronics and valuables out of its path. Do not stand under a ceiling that is sagging or dripping heavily, because it may hold more water than it looks.
Minute five: record, then call
Take photographs and a short video of the damage and the source, with the date visible if you can. Then call for help, and give a short, factual description: what is happening, where, what you have already shut off, and whether anyone is at risk. For a checklist of details that help, see how to brief a plumber. Check the licence of whoever you choose on the NSW Fair Trading licence check.
What to avoid in those minutes
- Do not search for tools before closing the valve.
- Do not flush, run taps or use machines to see whether the problem is fixed.
- Do not pour chemicals into a blocked drain, especially mixed ones.
- Do not open a hot water unit casing or its relief valve.
- Do not ignore a smell of gas, even if it is faint.
After the five minutes
You have not fixed anything; you have bought time. Now decide how urgent the repair is. Emergency plumbing helps you sort what must happen today from what can wait, and burst pipes explains the common causes and repairs. If sewage is involved, keep people and pets away until it is dealt with properly.
