This week is Mental Health Awareness Week, and we’re shining a light on an issue that hits close to home in our industry.

Construction can be tough, both on-site and off-site. Swipe to see some confronting stats about Mental Health in our industry (thanks to Mates in Construction).

At Semtex and Nuflow, our people come first, and that means looking after mental health as well as physical safety.

Use this as a reminder to check in on your mates! Ask how they’re really going. Listen without judgment. A simple chat can make a big difference.

Te Papa project update 🚧

Our team is working through the installation of stainless steel water pipework throughout the laboratory, forming part of the services on site.

Good progress from the team as this stage of the project continues to move forward.

No digging. Less disruption. Big results. 👊

Another pipe brought back to life with trenchless relining, giving damaged pipework a strong new lining from the inside, without the mess of a full replacement 🔧

Tryp project update 🔧

Levels 1, 2 and 3 of the main building have finished fit-off, with the plant room also complete.

Overall fit-off is now around 80%, and second-fix works have started on the existing heritage Level 1.

Great progress from the team as we keep moving through the final stages of the project.

☀️ Daylight Saving is here this weekend!

As the clocks go forward, it’s a good reminder to give your home a quick plumbing check and make sure everything’s sorted for the warmer months ahead. 💧🔧

✅ Check taps for drips or leaks
✅ Look under sinks for signs of moisture or water damage
✅ Check toilets aren’t constantly running
✅ Test drains and make sure they’re flowing freely
✅ Check outdoor taps and hoses for leaks
✅ Clear leaves and debris from gutters and downpipes
✅ Check around your hot water cylinder for leaks
✅ Listen for unusual noises from pumps or plumbing
✅ Keep an eye out for damp patches, mould or unexplained water
✅ Check that your water pressure feels normal

A few quick checks now could save you heaps on water bills and help catch small problems before they turn into expensive ones.

That little hose under your sink? It could cause a very big problem. 💦

Flexi hoses are found throughout most homes, under sinks, behind toilets and connected to appliances, but they're often forgotten about until something goes wrong.

Keep an eye out for:
🔍 Rust or corrosion
🔍 Bulging or swelling
🔍 Leaks or dampness
🔍 Kinks, twists or fraying
🔍 Old hoses you can't remember being replaced

A quick check now could save you from a flooded cupboard (or worse) later.

We tried to write a joke about a leaky tap. Couldn't make it stop. 💦
