FAQs
Why should I consider modern pipe upgrades for my Cowan home or business?
Many Cowan properties still rely on ageing galvanised steel or early-generation copper and polybutylene pipes. These older materials corrode, restrict water flow, and can leach rust or chemicals into your drinking water. Modern pipe upgrades—using PEX, Type L copper or trenchless lining—restore full water pressure, improve water quality, lower the risk of leaks, and add value to your property while meeting current Australian Standards (AS/NZS 3500).
What modern techniques do you use to replace or rehabilitate pipes?
We tailor the solution to the problem. Options include: • PEX repiping: Flexible, corrosion-resistant tubing fed through walls with minimal cutting. • Copper repiping: Type L hard-drawn copper for high-temperatures or exposed areas. • Trenchless pipe relining: An epoxy-saturated liner inserted and cured in place to create a seamless new pipe inside the old one—ideal for sewer and stormwater lines. • Pipe bursting: The old pipe is fractured and displaced while a new HDPE pipe is pulled in behind it. • Hydro-jetting and descaling: High-pressure water removes internal buildup before lining or to extend pipe life.
How disruptive is a pipe upgrade and how long does the work take?
With today’s minimally invasive methods, 80 % of our Cowan upgrades are completed within one to three days. PEX or copper repipes usually take 1–2 days for an average three-bedroom home, and water is typically off for only 2–4 hours while changeovers are made. Trenchless sewer relining can be finished the same day without digging up driveways or landscaping. We schedule work in stages, protect floors and furniture, and always leave a clean site.
What costs are involved and can I get an estimate before committing?
Costs vary with pipe length, accessibility, and material choice, but most residential water line upgrades in Cowan fall between $3,000 and $8,000, while trenchless sewer relining ranges from $120 to $250 per metre. We provide a free on-site inspection, pressure test, and itemised quote so you know the exact price before work starts. Finance plans and staged upgrades are available.
Are modern pipe materials safe and how long will they last?
Yes. All materials we install are WaterMark-certified and comply with AS/NZS 4020 (Products for use in contact with drinking water). PEX has a projected lifespan of 50+ years, copper 70+ years, and cured-in-place epoxy liners 40–50 years. They resist corrosion, scale, and chlorine degradation far better than older galvanised or polybutylene piping.
Do you offer warranties and post-installation support?
Every pipe upgrade comes with a written workmanship warranty of 10 years for repiping and 25 years for trenchless relining, in addition to manufacturer warranties on materials. We perform a final camera inspection, provide video footage, and return after 12 months for a complimentary check-up. Our Cowan team is on call 24/7 for any concerns and will lodge Council compliance certificates on your behalf.
