Frequently Asked Questions

How durable is TradePex?

The design life of our pipe is in excess of 50 years when installed in accordance with approved standards and application. Backed by our 25-year manufacturer's warranty with supplier backed support, we’re in for the long haul.

Can I use TradePex to connect to solar panels?

No. Like all other PEX systems, TradePex mustn’t be used to connect between a solar panel or other uncontrolled heat sources outside recommended working temperatures.

Can I use TradePex pipe that has been kinked?

No. The damaged section of pipe must be cut out and replaced. Another job for the apprentice.

Can I connect TradePex to other pipe systems of a different material?

Yes, we’ve got you sorted. We offer threaded fittings, brazing adapters, copper flare connectors and more to enable quick connection to other pipes.

Is TradePex UV stable?

Short-term exposure to direct sunlight is ok. Unless sleeved or lagged, TradePex must not be permanently installed where it will be exposed to sunlight.

How is TradePex installed?

A brief five step guide showing how easy it is to install is available in the TradePex Brochure.

What is the TradePex warranty?

All TradePex products are covered by a 25-year insurance backed warranty. We’ve put our money where our mouth is, because we know our pipes will get the job done – and no job’s worth doing unless it’s done well. So rest easy knowing we’ve got your back for the quarter century.

Do I need to use TradePex tools?

TradePex tools are specifically designed for use on the TradePex system. You must use TradePex pipe expanders for sleeve joints to ensure the system is warranted.

Other approved brand tools may be used for crimp joints, if they meet our high standards. Check with your local TradePex rep to make sure you’re

What is the TradePex Code of Practice?

Local authority approval

Double-check with your local authority before installation. Some authorities may have special requirements.

Storage and handling

TradePex pipes should be covered if they are being stored in direct sunlight for more than 30 days. Although flexible, avoid scoring or crushing the pipe. Pipe installed externally or between walls
must be enclosed in protective material to avoid UV or wear damage. Do not place heavy or sharp objects on top of pipe.


TradePex pipe can be repeatedly flexed without harm. The recommended minimum bending radius is eight-times the pipe diameter. Where tighter bends are required, you’ll need elbow or bend supports. Avoid over-bending or buckling the pipe. If kinked, the damaged section must be replaced.

Under concrete

TradePex must be installed in accordance with AS/NZS3500 or local authority requirements.

Just make sure you install the pipework in a conduit and avoid joints under concrete.

Concrete walls

Pipe should be placed in a formed chase, wrapped with a sealed, flexible material. Avoid joints wherever possible.


Spacing between supports should meet AS/NZS3500. Use purpose-made clips to allow free thermal movement. Don’t use metal pipe clips.


Do not pull pipe tight during installation. This will restrict movement during expansion and contraction.


The expansion rate for our pipe is roughly 1.4mm per 1°C temp change for every 10m of pipe. Allow for expansion based on this value. Pipes must not be anchored rigidly or pulled tight between fixed points.


Once you’re done, the install must be pressure tested, as per supplier specification sheet. When testing an existing installation, cap the addition and test it independently (as existing pipework and fixtures may be damaged by the high pressure).
