Kellyville facts that change a plumbing job
Recycled water, all or part
Sydney Water's Rouse Hill scheme serves all or parts of Kellyville. It's a second supply with its own pipes and meters, marked in purple, and has run in the area since 2001.
Big houses, big households
In 2021, 87.7% of occupied homes in the suburb were separate houses and 78.2% had four or more bedrooms. The average household was 3.3 people, against 2.6 across NSW.
The Hills Shire Council
Kellyville is in The Hills Shire. Kellyville Ridge falls under Blacktown City Council.
Your pipe, your fix
The Hills Shire Council treats sewer and stormwater pipes as the owner's to maintain, and won't remove a public tree because a private pipe is blocked.
Do you have recycled water?
- A second water meter that's purple.
- A purple garden tap, which should carry a 'not for drinking' sign.
- Recycled water charges on your Sydney Water bill.
- In some new homes, a clearly marked recycled water connection in the laundry for the washing machine.
Why it matters on every job
Recycled water is for the garden, toilets, ornamental ponds and a washing machine plumbed for it. Never use it for drinking, cooking, bathing, filling a pool or an evaporative cooler, or cleaning inside the house.
Sydney Water says there must be no cross-connection between the two systems, and that only licensed plumbers may do plumbing and drainage work, which it calls particularly important for recycled water. Before a plumber moves a tap, adds a garden line or connects an appliance, they need to know which supply each pipe carries.
Hot water for a full house
With 3.3 people in the average home, hot water works harder here than in the typical NSW household. If yours runs out before the last shower, size the replacement on people and bathrooms with our hot water size tool, then see hot water replacement in Sydney.
In NSW a tempering valve is required when a water heater is replaced, even like for like, so it belongs in any quote.
Roots and The Hills
The Hills Shire Council says roots are not known to get into well-maintained pipes. They usually find their way in through deteriorated pipe or failed joint seals. A blockage in a private pipe isn't grounds for removing a street tree, and Council won't consider claims about sewer or stormwater plumbing.
On your own land, pruning a tree by more than 10%, or removing one that isn't exempt, needs consent. So the fix is usually the pipe: see tree roots in drains and pipe relining in Sydney.
What we would do
If you're on the recycled water scheme, photograph both meters and your purple taps before any plumber starts, and ask them to confirm which supply each pipe is on. It heads off the one mistake that matters most here. For a slow drain near a street tree, ask for a camera inspection before anyone mentions the tree. Then we'll match you with a plumber who specialises in the job you've described.
