Mr. Water Professional Water Treatment of Maryland is a local well water softening and conditioning company specializing in new system sales and the maintenance/repair of Residential and Light Commercial Ultraviolet (germicidal) Lights in Maryland and the surrounding Tri-State area. Not installing your new U.V. light in the proper manner will only void the manufacturers warranty; it will eventually render it ineffective against the bacteria and viruses for which it was originally installed. All manufacturers of ultraviolet lights have similar influent water quality requirements that must be met at the time of installation and maintained throughout the service life of the unit.

The following water quality and installation standards for an Ultraviolet Disinfection System are:

  • No Sulfur
  • No Turbidity or other Filterable Solids
  • No greater than 0.3ppm of Iron
  • No greater than 0.05ppm of Manganese
  • No excessive Hardness (Where total hardness is less than 7gpg, the UV unit should operate efficiently provided the quartz sleeve and/or sensor probe is cleaned periodically. If total hardness exceeds 7gpg, the water should be softened).
  • A flow restrictor must be installed for the flow rating and disinfection requirements that the application requires.
  • The system must be sized based on the projected flow rate needed for the proper functioning of plumbing systems.
  • All germicidal 254nm bulbs are rated for a service life of approximately 9,000 hours (one year is 8,760 hours), and even though they can remain lit for a much longer period of time, their intensity and disinfection capacity are greatly reduced.
