UV Water Purification Systems in Southern NH
UV water treatment can inactivate microorganisms in private-well water when the system is correctly selected, installed, and maintained. A.J. LeBlanc Heating uses the independent laboratory result, water conditions, flow rate, and selected equipment's verified performance claims before recommending a system. Our licensed New Hampshire plumbers install and service the equipment.
Chemical-Free Bacteria Protection for Well Water
UV water treatment exposes water to ultraviolet light that inactivates microorganisms by damaging their genetic material. Performance depends on the unit's rated dose, water clarity, flow rate, and required pretreatment. We use an independent laboratory result and the selected system's certified claims before recommending equipment. A testing fee applies unless you provide recent results.
A Trusted Choice in Southern NH, Family-Owned Since 1928
Helps Reduce Bacteria and Viruses
A properly selected UV system can address microorganisms covered by that model's certified performance claims. Sediment, color, hardness, iron, and manganese may need to be corrected first so the UV light can reach the water effectively.
No Chemicals Added
Unlike chlorination, UV purification adds nothing to your water. No taste, no odor, no chemical byproducts.
Licensed NH Plumbers
Our licensed New Hampshire plumbers install UV systems on the home's main water line and confirm the equipment is set up correctly.
Annual Lamp Replacement
The VIQUA systems we install call for lamp replacement on the manufacturer's schedule, commonly every 12 months. Annual service can include the lamp, quartz-sleeve inspection and cleaning, alarms, and an operational check for the installed model.
UV Purification System Configurations
Whole-House UV Purification Installation
A point-of-entry UV system is installed on the home's main water line after required pretreatment, so water flowing through that line receives UV treatment before reaching the fixtures.
- 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
- Lamp alarms and optional fail-safe shutoff features, depending on the model
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 post-filter for taste and odor improvement
- Iron filtration if needed upstream of UV
- Complete well water treatment in one system
- Single annual service covers the entire system

Frequently Asked Questions
Does UV purification inactivate bacteria and viruses?
A properly selected UV system can inactivate microorganisms covered by that model's verified performance claims when the required dose, flow, water clarity, and pretreatment conditions are maintained. The independent laboratory result and equipment certification determine the system we recommend. It requires adequate UV dosage and clear water. Turbid water can reduce effectiveness, which is why a sediment pre-filter is recommended.
Is UV purification safe?
UV treatment does not add a disinfecting chemical to the water. It uses ultraviolet light to inactivate microorganisms, and it does not treat hardness, sediment, metals, taste, or odor. The system must be correctly sized and maintained for the intended disinfection performance.
How often does the UV lamp need to be replaced?
For the VIQUA systems we install, lamp replacement is commonly scheduled every 12 months even if the lamp still glows. We follow the exact model's manual, inspect and clean the quartz sleeve as needed, and reset the controller after service.
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. A laboratory result can change after flooding, well work, or another contamination event. We use the test history, well conditions, and homeowner's goals to determine whether ongoing UV treatment and a follow-up testing plan make sense.
