When did you last service your Davey Centurion UV water filter? Is your Centurion UV system beeping, showing alerts, or not performing at its best? If so, it’s time to book your annual UV water filter system service by a trained professional.
Professional servicing is essential. While the Davey Centurion UV system is reliable, it requires precise maintenance, technical handling, and proper safety measures. Below are the five key reasons why Aqua Works is the trusted choice for Centurion UV servicing in Warkworth and greater Auckland.
Davey Centurion UV Water Filtration System
The Davey Centurion UV Water Filtration System provides dependable ultraviolet treatment to support clean, potable water throughout your home. Supplied and supported by Aqua Works, this system helps manage microbiological risks in household water while maintaining fresh taste and clarity at every tap. With practical, proven technology and local expertise, Aqua Works delivers water treatment solutions designed for everyday New Zealand conditions.
1️⃣ Hazardous Pitfalls of Servicing the Centurion UV System Yourself
Why DIY Servicing Is Risky
- The quartz sleeve must be removed and cleaned every 6–12 months. It is extremely fragile and can easily crack during handling.
- If the quartz sleeve breaks, glass shards may enter the water chamber, posing a severe health risk.
- Air trapped inside cartridges or the UV chamber can enter the plumbing, causing water hammer, which can damage the system.
- UV lamps contain mercury and can release dangerous fumes if broken.
- Bacteria can enter the system during servicing unless the water lines are properly sterilised afterward.
How Aqua Works Prevents These Risks
- Our service vehicles carry every spare part needed, allowing us to complete 99% of jobs in a single visit.
- Our technicians have years of specialised experience with Davey, Microlene, and Aquashield UV systems.
- We strictly follow manufacturer guidelines, including full pipe sterilisation after servicing, ensuring your water is 99.9% free from E. coli.
A research review published on ResearchGate highlights that UV disinfection performance depends on multiple technical factors, including lamp intensity, water clarity, quartz sleeve condition, system design, and flow rate consistency. The study emphasises that incorrect handling or poor system setup can significantly reduce UV effectiveness. These findings reinforce why DIY servicing is risky: maintaining optimal UV performance requires specialised knowledge, precise calibration, and experience with the system’s critical components. By relying on Aqua Works’ trained UV experts, you ensure every part of your Centurion system is correctly evaluated, cleaned, calibrated, and safely restored for maximum protection.
2️⃣ Beeping Alerts in Your Davey Centurion UV System
Why Your Davey Centurion UV System Is Beeping
A beeping Centurion system is a sign that something needs attention. Common causes include:
- Low UV lamp life, most UV lamps must be replaced every 12 months.
- Faulty or incorrectly installed UV lamp.
- Voltage fluctuations or power outages.
- Dirty or malfunctioning sensors.
- Internal wiring or circuit issues.
How to Stop the Beeping
Basic steps include:
- Checking the user manual
- Holding down the reset/silence button
- Looking up model-specific videos
However, the safest and most effective solution is to contact a trained UV specialist.
Aqua Works services UV systems across Rodney, Kaipara Flats, Warkworth, Coatesville, Matakana, and Mangawhai, with over 20 years of experience across all major UV brands.
Regular servicing protects your home from harmful microorganisms and keeps your UV system running smoothly.
We Service Older Davey UV Models Too
Even if your Davey UV system is an older model, Aqua Works can help. We service trusted units such as the Steriflo, XL60, and Aquashield Max, providing professional maintenance, fault diagnostics, and UV lamp replacement to keep your system running smoothly and reliably.
3️⃣ Your Health & Safety Depend on Proper UV Handling
The Davey Centurion UV system uses powerful UV-C light to disinfect water. Incorrect handling exposes you to risks such as:
- Eye damage and severe irritation
- Skin burns caused by UV-C radiation
- Permanent vision loss if exposed directly
- Toxic mercury fumes if the lamp breaks
Most systems do not include warning stickers, meaning many homeowners don’t realise the danger.
Aqua Works technicians are trained to safely dismantle, replace, and reassemble UV systems without exposing you to UV-C radiation or harmful contaminants.
Choose an expert for your Puretec UV filter service who will take the necessary precautions to ensure the system is safely maintained and cared for. This way, you don’t have to worry and stay safe. Call us on 0800 278 288.
4️⃣ Proper Installation = Proper Performance
Only a registered plumber in New Zealand can legally install a UV water filtration system. However, many installations done by general plumbers lead to long-term servicing issues.
Common Installation Problems
- Systems placed under houses or in cramped areas, making maintenance unsafe
- Not enough clearance to remove the UV lamp straight out of the chamber
- Incorrect system sizing (too large or too small for the home)
Why Aqua Works Installs UV Systems Correctly
- MASTER-certified plumbers assess your home’s water usage, tank location, pressure, and layout
- We choose a placement that is safe, accessible, and future-proof for annual servicing
- We ensure correct flow direction, pipework, and clearance, preventing future repairs or system failures
