Backflow Testing in Porirua

At LB White, a big part of our work happens quietly.

No headlines. No fanfare. Just steady, compliant, professional backflow testing that keeps Porirua’s drinking water safe,, every single day.

We’re proud to serve the Porirua community by testing and maintaining backflow prevention systems across some of the city’s most important facilities.

Working Directly with Porirua City Council

We carry out testing on behalf of Porirua City Council at key public sites, including:

• Arena Aquatics
• Cannons Creek Pool
• The sewerage treatment plant out through Titahi Bay

These are high-risk sites where water safety is critical. Backflow prevention devices ensure that contaminated water can’t reverse back into the public supply during pressure changes.

It’s technical work. It’s regulated work. And it has to be done properly.

Hospitals, Embassies & High-Security Sites

We’ve been trusted for years to test at the local hospitals, facilities where compliance, safety, and documentation standards are non-negotiable.

We also service embassies and sites requiring discretion. These environments demand professionalism, confidentiality, and precision.

Supermarkets & Essential Services

Every major supermarket in Porirua relies on compliant backflow systems. We test, repair, and maintain these devices to ensure food retail environments remain safe and fully certified.

Beyond that, we service:

• Hairdressers
• Veterinary clinics
• Restaurants & cafés
• Mechanics
• Industrial workshops
• Commercial kitchens
• Office buildings
• Multi-storey buildings (including sprinkler systems and server rooms)

If a business is connected to the water supply, there’s a good chance we’re involved.

From Large Infrastructure to a Single Garage

Backflow prevention isn’t only for big sites.

Sometimes it’s a single device installed in a residential garage workshop. Sometimes it’s a multi-level commercial building with multiple testable devices protecting fire sprinkler systems.

We handle it all, from one preventer to entire facilities.

Why It Matters

Backflow occurs when pressure changes in the main water line cause water to reverse direction. Without a functioning prevention device, contaminated water can flow back into the public supply.

That’s why annual testing is mandatory for many properties.

Our job is to:

• Test each device
• Repair where needed
• Certify compliance
• Ensure Porirua’s water remains protected

It’s technical work. It’s regulated. And it directly protects the community.

Proud to Serve Porirua

We don’t just work here, we’re part of the local network of businesses, property managers, and council teams that keep this city running.

From public pools to hospitals, supermarkets to small workshops, LB White is committed to keeping Porirua compliant, safe, and flowing.

If you’re unsure whether your site requires testing, or if your certification is due, get in touch. We’ll make sure it’s sorted properly.
