FAQs
Why should I consider upgrading my existing pipes to high-quality materials?
Older galvanised steel or thin-wall copper lines common in Cowan homes are prone to corrosion, scale build-up, and pin-hole leaks. Upgrading to modern, premium-grade piping boosts water pressure, improves water quality, lowers the risk of burst lines, and can add value to your property. It also ensures compliance with today’s plumbing standards and can reduce your insurance premiums because the likelihood of water damage is greatly reduced.
What high-quality pipe materials do you install and how do they compare?
We routinely fit Australian-certified Type L copper, PEX-A cross-linked polyethylene, and HDPE (high-density polyethylene) for cold-water mains. Copper excels in heat resistance and longevity (50 + years), while PEX-A offers excellent flexibility for retrofits and outstanding freeze resistance. HDPE is highly impact-resistant and ideal for long external runs. All three materials carry WaterMark approval and meet AS/NZS 3500, so the choice depends on your budget, installation environment, and performance goals. Your plumber will walk you through the pros and cons of each during the site inspection.
How long does a complete pipe upgrade usually take in Cowan?
A straightforward, single-storey home re-pipe typically takes 1–2 days. Two-storey homes or properties with restricted access (for example, solid masonry or heritage features) can take 3–5 days. We stage the work so you’re rarely without water for more than a few hours, and we’ll always advise you of the exact timeline once we’ve surveyed your property.
Will pipe upgrades be disruptive to my household or business?
We use minimally invasive methods such as wall cavity fishing, under-floor access, and PEX manifold systems to limit demolition. Dust curtains, drop sheets, and end-of-day clean-ups keep your space tidy, and we coordinate water shut-offs around your timetable. For businesses, we can arrange after-hours or weekend work to avoid downtime.
Are your pipe upgrades compliant with local regulations and permits?
Yes. All work is carried out by NSW-licensed plumbers and is fully compliant with the Plumbing Code of Australia, AS/NZS 3500, and Ku-ring-gai Council requirements. We lodge the necessary ‘Notice of Work’ and comply with any council inspections, so you don’t have to handle the paperwork.
What can I expect in terms of cost and warranty?
Re-piping costs depend on property size, material choice, and accessibility, but most Cowan homes fall between $4,000 and $12,000. You ’ll receive a fixed-price quote up front—no hidden extras. All materials come with up to a 25-year manufacturer’s warranty, and we back our workmanship with a 6-year labour guarantee in line with the NSW Home Building Act.
