A plumbing emergency never waits for a convenient time. A pipe bursts at 2am, the hot water dies before work, or you smell gas over the weekend. When it happens in the Hawkesbury or Hills, staying calm and acting fast can save your home from serious water damage and keep your family safe. This guide walks you through exactly what to do for the most common plumbing emergencies, plus when to stop and call a 24/7 emergency plumber.

First, the one thing that stops most emergencies getting worse
Before you troubleshoot anything, know where your water shut off is. Turning off the water buys you time and stops a small leak becoming a flooded home. It is the single most useful thing any homeowner can do in a plumbing emergency, so read the next step even if nothing is wrong today.
Step 1: Shut off the water at the mains stop tap
Your mains stop tap controls all the water coming into your home. In most Hawkesbury properties you will find it in one of these spots:
- Near the front boundary or the water meter, usually inside a small green or black box in the ground
- Under the kitchen sink
- Along an external wall near the front of the house
- Inside the garage on older homes
Turn the tap clockwise until it stops. If you only need to isolate one fixture, look for a smaller isolation valve under the sink, behind the toilet, or beside the appliance and turn that instead. Take two minutes now to find your mains stop tap and show everyone in the house where it is. In an emergency you do not want to be searching in the dark.
Burst pipe: what to do right now
A burst pipe can release a huge amount of water fast, so move quickly and in this order:
- Shut off the water at the mains stop tap straight away.
- Turn off the electricity to any area where water is near power points, wiring or appliances. If water is anywhere near your switchboard, do not touch it and stay clear.
- Drain the remaining water by opening the cold taps around the house. This clears pressure and empties the pipes faster.
- Turn off the hot water system so it does not keep heating an empty tank.
- Contain the water with towels, buckets and a mop, and move furniture or valuables out of the way.
- Call an emergency plumber to find and repair the burst before you turn the water back on.
Do not try to patch a burst pipe permanently yourself. A temporary wrap can slow a leak, but a proper repair keeps it from bursting again in the same spot.
Gas leak: treat it as urgent and get everyone safe
A gas leak is the one emergency where safety comes before everything else. If you smell gas or hear a hissing near a gas line or appliance, act immediately:
- Turn off the gas at the meter or the bottle if you can reach it safely.
- Ventilate the area by opening doors and windows to let the gas escape.
- No flames or sparks. Do not light matches, do not smoke, and do not use candles or the stove.
- Do not touch electrical switches or appliances. Flicking a light switch on or off can create a spark, so leave them alone.
- Get everyone outside to fresh air, including pets.
- Call for help from outside the home once everyone is clear. If anyone feels unwell, call emergency services on 000 first.
Never try to find or fix a gas leak yourself. Gas work is licensed for good reason, and a qualified plumber has the tools to locate and seal the leak safely.

No hot water: quick checks before you call
No hot water is frustrating, but a few of the causes have a simple fix. Run through these checks first so you are not paying for a callout you did not need:
- Check the pilot light on a gas system. If it has gone out, follow the relighting instructions on the unit. If it will not stay lit, stop and call a plumber.
- Check the circuit breaker for an electric system. A tripped switch at the meter box is a common and easy cause. Reset it once, and if it trips again leave it off and call for help.
- Look for a leak around the tank or a pressure relief valve dripping constantly. Water pooling under the unit points to a fault that needs a plumber.
- Listen for unusual noises like banging or rumbling, which can signal sediment build up in the tank.
- Check the age of the system. Most units last around 10 to 15 years. If yours is older and failing, it may be time for a replacement rather than a repair.
If the basics check out and you still have no hot water, a plumber can diagnose the fault and get you back to warm showers fast.
Blocked drain or sewage overflow: first steps
A blocked drain can quickly turn into a health hazard if sewage starts backing up. Act carefully:
- Stop using water throughout the house. Every flush, sink and shower adds to the backup, so hold off until the blockage is cleared.
- Keep clear of the overflow. Sewage carries bacteria, so avoid contact and keep children and pets away.
- Check for an overflow relief gully outside, usually a lower grated drain near the house. It is designed to release the overflow outside rather than inside your home. Keep it clear.
- Skip harsh chemical drain cleaners. They rarely shift a serious blockage and can damage pipes and make the professional repair harder.
- Call an emergency plumber with drain clearing equipment to locate and remove the blockage properly.
Repeated blocked drains often point to tree roots, damaged pipes or a build up further down the line. A plumber can use a camera inspection to find the real cause so it does not keep happening.
