FAQs
Why should I consider upgrading my existing plumbing pipes for water efficiency in Cowan?
Ageing galvanised or copper pipes often have hidden leaks, internal corrosion and narrower internal diameters that waste water and energy. By replacing them with modern PEX-A, PEX-B or recycled-content copper, you lower friction losses, stop seepage and improve flow so fixtures reach working pressure faster and use less water. In Cowan, where Sydney Water’s pricing structure rewards lower consumption, most households see a 10–25 % reduction in water usage after an upgrade, translating to noticeable savings on quarterly bills.
What pipe materials are most suitable for a water-efficient upgrade?
For domestic applications we generally recommend cross-linked polyethylene (PEX) or WaterMark-approved recycled copper. PEX is flexible, needs fewer fittings, resists scale build-up and has excellent thermal properties, minimising heat loss in hot-water lines. Recycled copper offers robust longevity and a smaller environmental footprint than newly mined copper. Both materials carry Australian Standard AS/NZS 3500 and WaterMark certification, ensuring they meet Sydney Water requirements and are safe for drinking-water use.
How will a pipe upgrade actually reduce my water bills?
1. Leak elimination – New pipes eliminate the pinhole leaks common in older plumbing, preventing the continual background loss that can add 20 kL or more to your annual consumption. 2. Faster delivery – Smoother internal surfaces mean hot water arrives at the tap quicker, so you waste less cold water waiting. 3. Pressure optimisation – Correctly sized lines maintain optimum pressure, allowing modern WELS 4–6 star fixtures to operate efficiently. 4. Future-proofing – Upgraded plumbing supports appliances like rainwater top-up systems and greywater reuse, which further reduce reliance on mains supply.
Will replacing my pipes damage walls, floors or landscaping?
We use non-invasive methods wherever possible. Inside, PEX can often be ‘fished’ through existing wall cavities, avoiding large sections of plaster removal. When walls must be opened, we confine cuts to the smallest patchable areas and reinstall insulation and sheeting before repainting. Outdoors, trenchless techniques such as pipe pulling or directional boring let us replace long runs under driveways or gardens with minimal surface disruption. We finish every job with full site clean-up and, if requested, arrange re-landscaping.
Do I need permits or inspections for a pipe upgrade in Cowan, and do you handle them?
Yes. Sydney Water and Hornsby Shire Council require that any alteration to potable-water supply lines be carried out by a NSW licensed plumber and comply with AS/NZS 3500. A Section 60 approval is not normally needed for straight pipe replacement, but a minor works notification must still be lodged. Our team manages all paperwork: we submit the ‘Plumbing Works’ notification, book the final compliance inspection and provide you with the Certificate of Compliance on completion.
What is the typical timeframe and cost for a water-efficiency pipe upgrade?
Most three-bedroom homes in Cowan take 1–2 days for internal pipe replacement and an additional day if the external service line from the water meter to the house is renewed. Costs vary with pipe lengths, access and material choice, but a standard PEX upgrade starts around $2,800–$3,600 inc. GST, while recycled copper averages $4,500–$5,200. We offer free on-site assessments and fixed-price quotes, and many customers recoup the investment through lower water and energy bills within 3–5 years.
