About the Hills District
Why Hills District plumbing has its own playbook
Established brick houses from the 1960s to the 1990s around Castle Hill and Baulkham Hills, newer estates toward Kellyville, and apartment towers near the metro stations.
Plumbing problems in the Hills District follow the region's housing and its ground. The same kinds of homes and the same local conditions repeat from one postcode to the next, so a plumber who works here knows what to expect before a wall is opened.
The 3 suburbs we list as core coverage — Castle Hill, Baulkham Hills, Kellyville — are covered by local plumbers. Surrounding postcodes are also covered; tell us your suburb on the quote form and we'll give you a real ETA.
What we see most
Common Hills District plumbing patterns
Four problems account for most plumbing emergencies across the Hills District. Each comes from the kind of homes built here and the ground they stand on.
- 1
Hot water systems too small for large households
- 2
Leaks in pipes under concrete slabs on clay soil
- 3
Gas line work for cooktops, heaters, pools and outdoor kitchens
- 4
Stormwater problems on sloping blocks
Big houses, long pipes
A Hills District house has more plumbing in it than most Sydney homes: several bathrooms, a kitchen and a laundry a long way from the hot water unit, often a pool and an outdoor kitchen on gas. The common complaints follow from that. A hot water system that suited the house when it was built may not keep up with the way it is used now, and a long pipe run means a long wait for hot water at the far end and more joints that can leak.
When a hot water unit is replaced here, sizing it for the household rather than like for like is usually the better decision, and it is worth asking about the options: a larger storage tank, a continuous-flow gas unit, or a heat pump, which qualifies for rebates under the NSW energy savings schemes.
The emergencies we are called to most in the Hills
- No hot water, or not enough of it. In an electric storage unit, often an element or thermostat. If the tank is leaking from the base, it has to be replaced.
- A warm or damp patch on the floor. A leak in a pipe under the concrete slab, common on clay soil. Read the water meter with every tap off; if it moves, water is escaping.
- A smell of gas. Leave the house and ring Jemena on 131 909 first. Gas cooktops, heaters, pool heaters and barbecues are all common here.
- Stormwater against the house. On a sloping block, water that is not carried away ends up on the low side of the house. Keep grates and downpipes clear.
- Burst flexible hose or leak in a new apartment. In the towers near the metro stations. Turn off your own water and ring the building manager.
Clay soil and concrete slabs
The Hills sit on clay over shale, and clay moves with the weather: it swells when wet and shrinks when dry. Pipes buried in it are strained every season, and in houses built on a concrete slab the pipes under or through the slab are the ones that give. The signs are quiet: a warm or damp patch on a tiled floor, the sound of water with everything off, a bill that has risen, a hot water system that seems to run all day.
A leak under a slab is found with detection equipment before any concrete is cut, and often the better fix is a new pipe run around the slab rather than through it. Outside, the same movement cracks sewer lines at the joints, and roots from the large trees on these blocks follow. A drain that blocks repeatedly has a break in it that a camera will show.
Gas: who can touch it
More homes in the Hills run on gas than in most of Sydney: cooktops, ducted heating, hot water, pool heaters and barbecue lines. All of it, from the meter to the appliance, has to be installed and repaired by a licensed gasfitter, and the work comes with a compliance certificate. A plumber's licence alone does not cover it. Our gas plumber page explains what a gasfitter checks and what the work costs.
What an emergency plumber costs in the Hills District
Prices in the Hills are the same as anywhere else we work in Sydney: $120-160 an hour for emergency work at any hour, with no separate call-out fee. Distance adds a little to arrival times, not to the price. The larger jobs here are hot water replacements and slab leaks, both quoted in writing before any work starts.
- Hot water repair (element or thermostat)$200-400
- Hot water replacement (electric storage)$1,200-2,200
- Hot water replacement (gas instantaneous)$1,800-3,500
- Heat pump installation (after rebates)$3,500-5,500
- Hidden leak detection and repair$350-800
- Slab leak detection and repair$1,500-4,500

What to Do Right Now, Before the Plumber Arrives
Pick what is happening. These are the safe first steps to take in the next five minutes, before the plumber arrives.
Burst or leaking pipe: what to do now
Stop the water first, then deal with the mess.
- Turn the water off at the meter. It is usually in a box near your front boundary. Turn the tap clockwise, or turn the lever a quarter-turn so it sits across the pipe. In a unit, look for the isolation tap under the kitchen sink, in the laundry or in the bathroom.
- Keep water away from electricity. If water is near power points, lights or appliances, switch the power off at the switchboard — but only if you can reach it without standing in water.
- Drain what is left in the pipes. Open a cold tap at the lowest point of the house (a garden tap is ideal) and turn the hot water system off.
- Limit the damage. Put buckets and towels under the leak, move furniture and valuables, and take photos for your insurer.
Don't use electrical appliances in a wet room, and don't turn the water back on to test it.
Smell of gas: what to do now
Get out first. Make every call from outside.
- Don't touch anything electrical. No light switches, exhaust fans or appliances, and no flames or cigarettes. A single spark can ignite gas.
- Turn the gas off at the meter if you can reach it safely. The gas is off when the handle sits across the pipe.
- Open doors and windows and get everyone outside. Pets too. Stay out until you are told it is safe.
- From outside, ring Jemena on 131 909. That is the gas network's 24/7 faults and emergencies line for Sydney. If anyone feels unwell or there is a fire, ring 000. Ring Jemena: 131 909
- Then call a licensed gasfitter. The network crew makes the supply safe. Finding and repairing a leak on your side of the meter is a gasfitter's job.
Don't go back inside to look for the leak, and don't relight pilot lights yourself.
Sewage or drains backing up: what to do now
Every litre you send down the drain comes back up.
- Stop running water. No flushing, taps, showers, washing machine or dishwasher until the blockage is cleared.
- Keep people and pets away. Sewage is a health hazard. Wear gloves and wash well if you have to touch anything.
- Check the overflow gully outside. It is the grated drain against the wall near the laundry or kitchen. Clear pot plants and leaves off it, so any overflow happens outside and not through your floor drains.
- Ask next door. If the neighbours have the same problem, or sewage is coming up in the street, the blockage may be in the Sydney Water main. Report it on 13 20 90. Ring Sydney Water: 13 20 90
Don't pour chemical drain cleaner into a blocked drain. It rarely clears a sewer blockage, and it is dangerous for whoever opens the pipe next.
No hot water or leaking tank: what to do now
A leaking tank is urgent. A cold shower can usually be fixed the same day.
- Leaking tank? Turn off its water supply. Close the tap on the cold-water pipe going into the unit.
- Turn off its power or gas. Electric: switch off the hot water circuit at the switchboard. Gas: close the gas tap on the pipe to the unit.
- No leak, just cold? Electric: check whether the hot water breaker has tripped. Gas: check that your other gas appliances work and whether the pilot light is out — relight it only by following the instructions printed on the unit.
- Read the label. Note the brand, model and size printed on the tank. It lets us quote a repair or a replacement before we arrive.
Don't block or cap the relief valve that drips from the side of the tank. It is a safety device.
Overflowing or blocked toilet: what to do now
Stop the water going in before you do anything else.
- Turn off the tap behind the toilet. It is the small tap on the wall or floor beside the cistern. Turn it clockwise.
- Don't flush again. If the bowl is still filling, lift the cistern lid and push the rubber flapper down, or lift the float.
- Mop up straight away. In a unit, tell the building manager if water may reach the apartment below.
- Check the other drains. If the shower or floor drain gurgles or backs up as well, the blockage is in the sewer line — follow the sewage steps.
Don't keep plunging once water reaches the rim, and don't use chemical cleaners.
General guidance only. If anyone is in danger, ring 000.
Hills District FAQs
Plumbing in the Hills District — what people ask
Do you have an emergency plumber in the Hills District at night and on weekends?
Yes. Our plumbers take emergency jobs across the Hills 24 hours a day, every day of the year, at the same $120-160 an hour that applies during the day.Why does the hot water run out so quickly in a large house?
Usually because the storage tank was sized for a smaller household, or the unit is old and its element or thermostat is failing. A larger tank, a continuous-flow gas unit or a heat pump are the usual options when it is replaced. A tank leaking from the base cannot be repaired.How do I know if I have a leak under the slab?
Look for a warm or damp patch on the floor, the sound of running water when everything is off, or a water bill that has gone up. Then turn off every tap, read the water meter, use no water for at least an hour and read it again. If it has moved, you have a leak, and detection equipment finds it before any concrete is cut.Can a plumber fix my gas cooktop or heater?
Only a licensed gasfitter can. Many plumbers hold both licences, but not all. Ask for the licence number and check it with NSW Fair Trading. Gas work in NSW comes with a compliance certificate when it is finished.How fast can a plumber actually reach the Hills District?
