FAQs
Why should I consider upgrading my old plumbing pipes?
Ageing pipes made from galvanised steel, poly-butylene or early copper alloys are prone to corrosion, scale build-up and pin-hole leaks. Upgrading eliminates the risk of sudden bursts, improves water pressure and quality, and brings your home up to current Australian Standards. A proactive pipe upgrade is usually far cheaper than repairing water damage and mould after a major leak, and it can add value to your Cowan property when you decide to sell.
What pipe materials do you recommend for long-term reliability in Cowan’s climate?
For most homes we recommend Type B copper or PEX-A (cross-linked polyethylene) with crimp or expansion fittings. Copper offers 50+ years of proven durability, excellent heat tolerance and high resistance to bushfire radiant heat—important in northern Sydney’s bush-adjacent suburbs. PEX-A is more flexible, resists corrosion, and can handle Cowan’s moderate temperature swings without the noise of thermal expansion. In some cases we use a hybrid system—copper risers with PEX distribution—to balance cost, performance and ease of installation.
How can I tell if my existing pipes are nearing the end of their service life?
Warning signs include rusty or brown water after periods of non-use, frequent pin-hole leaks, unexplained moisture in walls, sagging ceilings, reduced flow at multiple fixtures, and water hammer even after pressure reduction. If your home was built before the early 1990s and still has original pipes, the materials themselves may be obsolete or recalled. A licensed plumber can perform a pressure test and camera inspection to confirm the condition of concealed pipework.
What is involved in a whole-house repipe and how long does it take?
First we map your existing water and, if required, gas lines with electronic locating equipment. After shutting off the main supply, we cut small access openings in walls, ceilings or under the floor to remove old pipes section by section. New copper or PEX lines are then installed, pressure-tested to 1500 kPa, insulated and secured to prevent movement. Finally, we patch and paint all access points. A three-bedroom, two-bathroom home in Cowan typically takes 2–4 working days, with water service restored at the end of each day so you are never completely without supply overnight.
Will upgrading my pipes improve water efficiency and reduce utility bills?
Yes. Modern pipes have a smoother internal bore, which means less friction loss and the ability to deliver the same flow at a lower pressure setting. That lets us install a pressure-reducing valve calibrated to the optimum 350–500 kPa range, reducing both water and energy consumption (if you have a hot-water recirculation pump). New pipework also allows for easy addition of water-saving fixtures such as thermostatic mixing valves and smart leak-detection meters, all of which contribute to lower quarterly bills.
Are there any local regulations or permits required for pipe upgrades in Cowan?
Cowan falls under the Hornsby Shire Council and Sydney Water jurisdiction. While minor like-for-like repairs don’t usually need approval, any substantial pipe upgrade, especially one that alters the layout, must be performed by a NSW licensed plumber who can issue a Certificate of Compliance (Form 4) to Sydney Water. If sections of the work are outside the property boundary or involve connection to the water main, a Sydney Water Tap-in application may be required. We take care of all permits, inspections and compliance paperwork so you don’t have to.
