Private Well Water
Wells aren't treated by a municipal plant, which means bacteria and other microorganisms aren't automatically removed. UV is one of the most effective safeguards available.
Chemical-free disinfection that destroys bacteria, viruses and protozoa in seconds — the essential final step for well water and any home that wants true peace of mind.
Excalibur's Ultraviolet Sterilizer Systems expose your water to concentrated UV-C light as it flows through a sealed stainless steel chamber. That light disrupts the DNA of microorganisms — bacteria, viruses, algae and mold — so they can no longer reproduce or cause illness. No chlorine, no added taste or odor, no chemical byproducts.
It's fast-acting, low-maintenance (an annual bulb replacement is typically all it needs), and works continuously as water passes through your home's main line.
Wells aren't treated by a municipal plant, which means bacteria and other microorganisms aren't automatically removed. UV is one of the most effective safeguards available.
Any non-municipal water source — a lake, spring, or cistern — benefits from continuous UV disinfection to guard against contamination.
Even on municipal water, homeowners recovering from a positive water test or simply wanting a final layer of protection choose UV as cheap insurance.
Excalibur offers UV systems from the Optimum Series through premium Signature Series models, sized to your home's flow rate — we'll help you pick the right one after testing your water.
We'll test your water and tell you exactly what it needs — no guesswork, no pressure.
If your home uses a private well, a UV sterilizer is one of the most effective ways to protect against bacteria, viruses and protozoa that municipal treatment plants would normally remove. Many mortgage lenders and local health departments also recommend or require water testing (and sometimes UV disinfection) for well water before closing on a home.
No. UV sterilization uses ultraviolet light to destroy the DNA of microorganisms so they can't reproduce — there's no chlorine or chemical residue added to your water.
A whole-home UV sterilizer is installed at your main water line, typically after sediment and carbon filtration, so every fixture in your home receives disinfected water — not just a single faucet.
No. UV disinfection handles biological contaminants (bacteria, viruses, protozoa) but doesn't remove hardness, chlorine, sediment or chemicals. It's typically installed alongside a whole-house filter or softener as the final disinfection step.
The best way to know is a free in-home water test. If you're on well water, or you've had a positive coliform/E. coli test, a UV system is almost always worth adding.
Pair UV disinfection with an RO system for the purest possible drinking water at your kitchen tap.
