Ultraviolet (UV) Disinfection System: What Is It?

If you're looking for a safe and efficient way to disinfect your well or lake water, UV disinfection is the answer. Unlike chemical treatments, this non-chemical disinfection method harnesses the power of ultraviolet light to eliminate harmful bacteria while leaving the natural characteristics of your water untouched. No more compromise between safety and quality! What's even better is that UV disinfection systems come with an easy pre-assembled manifold, making installation a breeze. 


Types of UV Systems

When it comes to UV disinfection systems, there are different types to suit various needs.

  1. The first type is the whole house UV system, designed to ensure that every tap in your home delivers safe and bacteria-free water.

  2. Another option is an add-on UV system, which can be integrated into your existing drinking water system, such as a reverse osmosis (RO) unit, providing an extra layer of protection for your drinking water.

  3. Lastly, there are minirack or stand-alone UV systems, perfect for smaller spaces or situations where a dedicated UV disinfection setup is required.

Regardless of the type you choose, UV disinfection offers a reliable and non-chemical solution for maintaining the safety and purity of your water supply. At Water eStore, we have a wide range of UV systems to cater to your specific requirements.

UV System Maintenance 

  1. The UV lamp needs to be replaced once a year, whether it goes into alarm or not. The prefilters will need replacement at least once a year or more often if the flow slows down due to excess sediment in your water. The replacement procedure differs by make and model.  We have over 100 videos, email us a picture and we can help you identify what you have, what you need and which video shows you how to do the maintenance yourself.

  2. The UV sleeve needs to be cleaned whenever the lamp is replaced or more often if you do not have water filtration equipment before the UV to bring the water into the pretreatment requirements. You would need a descaler like CLR or even vinegar to get the UV lamp perfectly clean.  If you can’t get it clean, replace the UV sleeve.

  3. If you have a monitored UV, you will need to clean the sensor whenever you clean the sleeve.

  4. The ballast will last anywhere from 4 – 20 years.  There is no way to predict when it will need replacement, but you can definitely make it last longer by plugging it into a surge suppressor.

  5. Be sure to shut OFF your water and depressurize the system before opening anything up.

  6. Always be sure to have a spare sleeve on hand because they are very fragile and can easily be broken!  If you need one, your family won’t have any water until you get a replacement. >> SHOP REPLACEMENT LAMP AND FILTER BUNDLES HERE
