    The UV lightbulb arrived on time and in great shape. It was packaged well. It's been installed for the past 46 days without any issue. I will be ordering it again next year.

    Great Service!

    I watched Gary’s YouTube video which explained exactly how to change my uv bulb and change the prefilter. I ordered the replacement uv kit from them and had it within a day or two. Wonderful service, I definitely recommend The Water Store!

    About Sterilight

    Viqua Sterilight is a brand of ultraviolet (UV) water purification systems manufactured by Viqua. These systems use UV light to disinfect water, making it safe to drink and use for other purposes.

    The Sterilight systems work by passing water through a chamber containing a UV lamp. UV light penetrates the cell walls of microorganisms, such as bacteria and viruses, and disrupts their DNA. This prevents them from reproducing and effectively kills them, making the water safe to drink.

    One of the advantages of UV water purification is that it does not add any chemicals to the water, unlike other treatment methods such as chlorination. This makes it a popular choice for those who are concerned about the taste or smell of chemically treated water.

    Viqua Sterilight systems come in a variety of models to suit different needs. The company offers both residential and commercial systems, with flow rates ranging from 4 to 400 gallons per minute. Some models are designed for specific applications, such as well water or irrigation.

    The company also offers advanced features with its Sterilight systems such as digital displays, automatic lamp replacement reminders, and remote monitoring capabilities. This allows the user to monitor their system and receive alerts if anything is wrong.

    In addition to their water purification systems, Viqua also offers a range of accessories and replacement parts to ensure that the Sterilight systems are operating at optimal performance. They also provide technical support and customer service to help customers with the installation, operation, and maintenance of their systems.

    Overall, Viqua Sterilight is a reliable and effective water purification solution that uses UV light to disinfect water. These systems are available in a range of sizes and models to suit different needs and are an excellent choice for those who are concerned about the taste or smell of chemically treated water. They also offer advanced features and monitoring options to ensure the system is running optimally.
