UV Water Purification Systems in Southern NH
UV purification helps reduce bacteria, viruses, and pathogens in well water without chemicals. Installed by licensed NH plumbers.
Chemical-Free Bacteria Protection for Well Water
UV water purification uses ultraviolet light to inactivate microorganisms without adding chemicals. Effective disinfection depends on the selected system, water clarity, flow rate, and proper maintenance. If a well tests positive for coliform bacteria, we review the results and treatment requirements before recommending equipment.

Helps Reduce Bacteria and Viruses
UV light targets E. coli, coliform bacteria, Giardia, Cryptosporidium, and hundreds of other waterborne pathogens.
No Chemicals Added
Unlike chlorination, UV purification adds nothing to your water. No taste, no odor, no chemical byproducts.
Licensed NH Plumbers
All UV system installations by licensed NH plumbers. Properly installed on your main water line.
UV Lamp and Sleeve Care
UV lamps lose effectiveness over time. Replacement timing and sleeve cleaning follow the model requirements and water conditions. We offer annual service.
UV Purification System Configurations
Whole-House UV Purification Installation
A UV purification unit is installed on your main water line after any filtration, so every tap in your home is protected.
- Installed on main water line for whole-house protection
- Helps reduce bacteria, viruses, cysts, and other pathogens
- No chemicals, no taste or odor change
- Works in seconds, no holding tank required
- Bypass valves for service and maintenance
Combining UV with Sediment and Carbon Filtration
UV works best when paired with a sediment pre-filter. Turbid or iron-heavy water can shield microorganisms from UV light. We design complete systems that address all your well water issues together.
- Sediment pre-filter removes particles before UV chamber
- Carbon filtration for taste and odor improvement before the UV unit
- Iron filtration if needed upstream of UV
- Pretreatment and UV matched to your water-test results
- Coordinated service for UV and pretreatment equipment
Planning UV as Part of Well Water Treatment
Water-test results and household flow help determine suitable pretreatment and UV equipment. Sediment, iron, hardness, or colored water can affect how the unit performs. Our well-water treatment service can address additional concerns identified in testing.
UV belongs after the required pretreatment, and the lamp and sleeve need space for service. Our guide to what UV does and does not remove explains how disinfection fits alongside other treatment.

Frequently Asked Questions
Does UV purification kill all bacteria?
UV can inactivate microorganisms when the selected system delivers the required dose under its rated conditions. Water clarity, flow, lamp output, and maintenance affect performance. Pretreatment may be needed so particles and dissolved substances do not interfere with UV transmission.
Is UV purification safe?
Yes. UV purification adds nothing to your water. It simply exposes water to UV light that destroys microorganism DNA. There are no chemical byproducts and no effect on taste or odor.
How often does the UV lamp need to be replaced?
Follow the replacement interval for your UV model. Many lamps need annual replacement, while some series have longer intervals. A glowing lamp does not by itself confirm adequate UV output. The quartz sleeve also needs inspection and cleaning according to water conditions and manufacturer instructions.
Do I need UV if my well water tested clean?
A well can test clean one year and test positive for bacteria the next, especially after heavy rainfall or flooding. Many well owners install UV as a permanent safeguard regardless of test results.
Does UV remove arsenic, hardness, or chemical contaminants?
No. UV is a disinfection step, not a filter for dissolved chemicals or hardness minerals. Those concerns need treatment selected for your water-test results. UV also requires power and operation within the selected model limits; an alarm or power interruption needs attention before relying on the system.
