But Manukau also has a second problem: polybutylene (poly-B) pipes. Homes built in the late 1980s through to 2005 — particularly around Wiri and the newer subdivisions — used grey plastic poly-B piping. These pipes look fine from the outside but become brittle over time and can split without warning, flooding your home with no advance notice.
Whether it's corroded galvanised or ticking-time-bomb poly-B, we replace failing pipes in Manukau with copper or PEX (cross-linked polyethylene). Both materials are proven, long-lasting, and won't leave you with surprise leaks at 2am.
Brown or rusty water — corroded galvanised pipes shedding rust into your Manukau water supply.
Low water pressure — rust buildup narrows galvanised pipes, starving taps and showers of flow.
Pinhole leaks — small leaks appearing in walls or ceilings as corrosion eats through pipe walls.
Grey plastic pipes — if your Manukau home has grey poly-B pipes, they need replacing before they fail.
Pipes over 40 years old — Manukau's state housing galvanised pipes are well past their intended lifespan.
Frequent repairs — if you're patching leaks every few months, a full re-pipe saves money long-term.
A full re-pipe for a typical 3-bedroom Manukau home varies depending on pipe material and accessibility. Poly-B replacement in Manukau is often simpler than galvanised because the pipes are easier to access. We assess your Manukau property first and provide a fixed quote.
Poly-B pipes in Manukau homes are grey plastic, usually stamped with "PB" and a date code. Check under sinks, behind the hot water cylinder, and in the ceiling cavity. If your Manukau home was built between 1988 and 2005, there's a good chance it has poly-B. We can inspect and confirm for you.
Yes — poly-B pipes in Manukau don't give warning before they fail. They become brittle from chlorine in the water supply and can split suddenly, flooding your Manukau home. Insurance companies are increasingly wary of poly-B claims. We recommend replacing them before they fail.
Both are excellent for Manukau properties. Copper has a proven 50+ year track record. PEX is flexible, faster to install, and often more cost-effective for Manukau homes where pipes run through tight spaces. We'll recommend the best option after assessing your Manukau home.
