What is Dux Qest Plumbing?9 Feb 2021

During your building inspection, you may get introduced to Dux Qest pipes

So what even is Dux Qest?



This is an old redundant form of piping that was typically used in homes across New Zealand in the 1970's and the 1980's. They were galvanised steel pipes, which became an issue with rust.

While the exterior of the piping can appear ok, it's the inside of the pipe where the issues can occur including corrosion, leaks and water flow issues.

It's a very distinctive looking pipe that experts are able to identify throughout your property.

Why is Dux Qest even an issue?


Faulty, leaking pipes can cause massive issues to your property, with many issues only being identified after the leaking of potentially hundreds of litres of water.

Faulty plumbing can be the root cause of many costly renovation jobs that may not be covered by your insurance, so it pays to know this information before you buy a home so that you can factor this increase in costs in your purchase price.

How do I know if my Property has Dux Quest pipes?


The best way to identify this is by having a professional building inspector to review the property. A qualified building inspector will be able to advise whether the house is using Dux Qest plumbing and whether further investigation would be required.

These are important details that you need to be aware of when purchasing a home, as most insurance companies won't always pay out on Dux Qest piping issues, due to the product being so widespread when it was introduced.

You'll also get an idea and recommendation on whether the whole properties piping will need to be replaced, as opposed to just fixing and replacing the Dix Qest piping that is causing the property any issues.
