Have you recently serviced your VIQUA UV water filtration system? Is your Viqua Bug Buster UV system beeping, showing alerts, or not performing at its best? If so, it’s likely time for your annual professional servicing. Regular maintenance is essential to keep your home’s water clean, safe, and free from harmful microorganisms.
Manufactured in Canada, VIQUA UV systems are recognised worldwide for their quality and reliability. Previously known as Sterilight, some systems may still carry the Sterilight name, reflecting the brand’s long history and proven UV technology. Throughout this evolution, Aqua Works has spent more than 20 years serving Warkworth homeowners, building trusted expertise in UV water filtration systems including today’s VIQUA UV filter systems. Our certified technicians ensure your system continues to operate at peak performance, helping protect your household from bacteria, viruses, and waterborne contaminants.
Why Annual VIQUA UV Filter Servicing Matters
Regular UV servicing prevents system underperformance, protects your health, and ensures consistent disinfection. Here’s why it matters for every homeowner in New Zealand.
Below are the five key reasons homeowners choose Aqua Works to service their VIQUA UV water filtration system.
Viqua UV water filter system NZ
Aqua Works provides professional VIQUA UV Water Filtration System Service to help ensure your household water remains safe, potable, and suitable for everyday use. With expert servicing and support, VIQUA UV systems help reduce the risk of harmful microorganisms, delivering clear, fresh tasting water throughout your home with reliable performance you can trust.
1️⃣ Long-Term Expertise You Can Trust
Your Viqua UV water filtration system is designed to neutralise microorganisms in your water using powerful UV-C light. However, UV-C technology requires precise handling and consistent annual servicing. Because UV-C systems are highly technical, proper installation, calibration, and servicing must be performed by trained specialists to avoid system underperformance or safety risks.
Aqua Works technicians are highly trained in servicing Viqua UV systems, from the Bug Buster Pro and Gold UV’s to the Arros whole house units. We conduct a complete inspection, remove and clean the quartz sleeve, replace old UV lamps, check sensors, and ensure your system is operating safely.
A research study published by ScienceDirect on ultraviolet technology in urban water supply systems highlights that UV‑C disinfection is highly effective only when systems are expertly designed, calibrated, and maintained. The study explains that several factors can restrict UV performance, including water turbidity, fouling or scaling on the quartz sleeve, ageing UV lamps, inaccurate or unmonitored sensors, and inconsistent flow rates. These limitations require specialist technical knowledge and long‑term operational expertise to manage correctly, reinforcing why professional servicing is essential for consistent disinfection performance and safe drinking water.
2️⃣ Prevent Costly Mistakes & Protect Your Health
Costly DIY Errors
One of the most common mistakes homeowners make is mishandling the quartz sleeve.
This delicate glass tube protects the UV lamp but can easily crack if squeezed, overtightened, or incorrectly reinstalled.
If a quartz sleeve breaks:
- Glass shards may enter your system chamber
- Your water may become unsafe to drink
- Your UV lamp becomes ineffective
Health Risks During Incorrect Handling
The UV-C lamp in your Viqua system emits high-intensity ultraviolet radiation. Direct exposure can cause:
- Severe eye damage
- Skin burns
- Permanent vision issues
Additionally, UV lamps contain small amounts of mercury. If the lamp breaks, handling shards or inhaling fumes poses a serious health risk.
Our Aqua Works technicians follow strict safety protocols to protect both you and your water supply.
3️⃣ Say Goodbye to Beeping Alerts
If your VIQUA UV system is beeping, it’s signalling that something needs attention.
The causes can vary:
- Lamp expiry – UV lamps lose strength after 12 months
- Faulty or incorrectly installed lamp
- Power fluctuations affecting system stability
- Dirty or failing sensors
Instead of guessing, our technicians quickly diagnose the cause and restore your system’s performance. We specialise in troubleshooting Viqua Bug Buster and Viqua whole house UV systems, ensuring your water remains safe and your household remains undisturbed.
4️⃣ Proper Installation = Proper Performance
In New Zealand, only a certified plumber can legally install UV water filtration systems like the Viqua VH410 and VH200 whole house UV system. Incorrect installation can result in:
- Poor water flow
- Leaks or incorrect pipework
- Difficult maintenance access
- System inefficiency
Aqua Works manages the installation with MASTER-certified plumbers who ensure your unit is accessible, compliant, and positioned for efficient servicing.
We evaluate:
- System placement
- Water flow direction
- Accessibility for future servicing
- Correct pipe sterilisation procedures

5️⃣ Professional Service & Maintenance for Safe Drinking Water

Our comprehensive Viqua UV service includes:
- Full system performance test
- Quartz sleeve cleaning/replacement
- UV lamp installation & timer reset
- Sterilisation of water pipes to prevent bacteria entering the system during service
This crucial sterilisation step is often skipped in DIY servicing, yet it is essential to prevent contamination during maintenance.
With Aqua Works, your household enjoys clean, clear, safe drinking water that is 99.9% free from harmful microorganisms such as E. coli.

Frequently Asked Questions (FAQ)
1. How often should I replace my VIQUA UV lamp?
Every 12 months. UV lamps lose intensity even if they still “look” functional.
2. Why is my VIQUA UV system beeping?
Most often: expired lamp, faulty installation, sensor issues, or power fluctuations.
3. Do I need a certified technician to service my Viqua system?
No, however, NZ regulations require registered plumbers for UV installations, and servicing requires technical expertise from properly trained technicians.
4. What happens if I don’t service my UV system annually?
Reduced disinfection, higher risk of E. coli exposure, and possible system failure, which leads to your family’s health being jeopardised and put at risk.
5. Is VIQUA a Canadian made UV water filtration system?
Yes. VIQUA UV water filtration systems are manufactured in Canada and are widely used in residential and commercial water treatment applications worldwide. Canadian manufacturing is often associated with high quality standards and reliable performance, making VIQUA a trusted choice for New Zealand homeowners.
6. Is Sterilight the same as VIQUA?
Yes. Sterilight was the original brand name before it became VIQUA. The technology, manufacturing standards, and product range remain consistent, so some systems may still display the Sterilight name while using the same proven VIQUA UV components.
Which UV water filter brands do we service?
Aqua Works takes care of rural houses, farms and rural schools, as well as lifestyle blocks and commercial premises with rainwater, groundwater, tank water or service water.
