A service visit is designed to restore performance and confirm the system is operating safely and reliably. - Condition check of the UV chamber, fittings and seals - UV lamp replacement (where due) and correct handling of parts - Cleaning and inspection of the quartz sleeve (where fitted) - Electrical and control checks, including indicator lights, alarms and power supply - Flow and bypass checks to help ensure the UV dose remains effective - Review of any pre-filtration, as sediment can reduce UV performance - Leak check and restart, with practical advice on service intervals ### When this service is most useful This service is a good fit if you: - Use a private supply (for example borehole or stored water) and rely on UV for disinfection - Have noticed changes in taste, clarity, odour, or are concerned about water hygiene - Have moved into a property with an existing UV unit and want confidence it is working properly - Need planned maintenance for a rental property to reduce breakdown risk - Want to avoid unexpected lamp failure and keep running costs predictable ### How the service is delivered We start by reviewing the system layout and any recent issues. The unit is isolated safely, then key components are inspected, cleaned where required, and the lamp is replaced if due. Once reassembled, we run checks to confirm the system powers up correctly, operates without leaks, and is set up to support effective treatment. ### After the service: ongoing value You will know what was done, what condition the unit is in, and what to plan next. If we spot issues outside the UV unit, such as poor pre-filtration, incorrect flow control, or scale build-up affecting the installation, we will explain the options clearly. Where appropriate, we can also recommend water testing so any wider treatment needs are based on evidence, not guesswork.

Most UV lamps are replaced every 12 months, even if they still light up, because UV output reduces over time. A regular service helps you keep to the correct interval for your specific unit and usage. Does UV water treatment remove limescale, chlorine or metals? No. UV treatment is designed to inactivate microorganisms, not remove dissolved chemicals or hardness. If you need help with limescale or taste and odour issues, filtration or water softening may be more suitable alongside UV. What happens during a UV water treatment service? We isolate the unit safely, inspect the chamber and seals, clean key components, and replace the lamp if due. We then check controls and alarms, confirm there are no leaks, and make sure the system is operating correctly after restart. Will my water need to be turned off? Yes, there is usually a short interruption while we isolate and reopen the unit. We will keep downtime to a minimum and confirm everything is running normally before we leave. Can you install a new UV system if I do not have one? Yes. We can assess your water supply, flow rate and pipework layout, then specify a suitable UV unit and any required pre-filtration. If water quality is uncertain, we may recommend testing first to ensure the system is correctly matched to your needs.
