Plumber & Gasfitter for Manukau

Manukau is one of South Auckland's biggest suburbs — and one of the busiest for plumbing work. The area has a massive stock of 1950s-1970s state houses with galvanised steel pipes that are well past their lifespan, alongside 1990s-2000s homes with polybutylene (poly-B) pipes that are known to fail without warning. Then there's the Kainga Ora redevelopments bringing new housing that needs plumbing from scratch.

Water & Gas Worx handles everything — re-pipes, poly-B replacements, hot water cylinders, gasfitting, and drainage. Plumbing AND gas. Water and gas — it's what we do.

We know Manukau's housing stock. The state houses along Wiri Station Road and Barrowcliffe Place with their original galv pipes. The newer developments around Manukau Central and along the train line. The 1990s builds in Randwick Park and Clendon where poly-B is a ticking time bomb. Whatever era your home is from, we know what to look for.

Common Plumbing Issues in Manukau

Manukau's mix of old state houses, 1990s builds, and new developments means we see a wide range of plumbing problems. Here are the most common:

• Corroded galvanised pipes — The 1950s-1970s state houses across Manukau were built with galvanised steel water pipes. After 50-70 years, these pipes corrode from the inside out. You get brown water, restricted flow, and eventually pinhole leaks through walls and ceilings. Full re-pipe in copper or PEX is the only lasting fix — patching just delays the inevitable.
• Polybutylene (poly-B) pipe failures — Homes built in Manukau during the 1990s and early 2000s often used poly-B, a grey plastic pipe that degrades over time. It can split suddenly — one day it's fine, the next you've got water pouring through the ceiling. If your Manukau home is from this era, get it inspected before it fails on you.
• Aging hot water cylinders — Many Manukau homes still have original hot water cylinders that are 25-30+ years old. They're inefficient, expensive to run, and a flood risk when they finally give out. Replacement with a modern mains-pressure cylinder or continuous flow unit saves money and gives you better showers.
• Blocked and broken drains — Older Manukau properties have clay drain pipes that crack and let tree roots in. Combined with increased housing density putting more demand on aging infrastructure, drain blockages are one of our most common callouts across South Auckland.
• Non-compliant gas installations — Older gas hobs, heaters, and califonts that haven't been serviced or checked in years. Some don't meet current safety standards. As certified gasfitters, we test, service, and bring gas installations up to code — especially important if you're buying or selling.
