    Why Viqua Water System has no power?
    • J
      Justin RobinsonJul 27, 2025
      The Viqua Water System might not have power due to several reasons: the GFCI or breaker tripped (reset it), the transient voltage surge suppressor (TVSS) is damaged (replace it), or the controller is damaged (replace the controller and use a TVSS).

    What to do if the lamp timer on my Viqua Water System doesn't read anything?
    • K
      kevin85Jul 31, 2025
      If the lamp timer on your Viqua Water System isn't displaying anything, check the following: ensure the unit is plugged into a working AC power outlet, replace the fuse or reset the breaker if there's no power at the outlet, replace the power cord if it's damaged, or replace the controller and use a surge protector (TVSS) if a power surge damaged the electrical assembly.

    Why does the GFCI or breaker repeatedly trip on my Viqua Water System?
    • D
      David ZimmermanAug 6, 2025
      If the GFCI or breaker repeatedly trips on your Viqua Water System, it could be due to a wet connection between the lamp and lamp plug (clean and dry them, and check for leaks or condensation) or a short-circuit in the electrical assembly (replace the controller).

    What to do if Viqua Water System is operating but water tests show bacterial contamination?
    • A
      Anita CurryAug 10, 2025
      If your Viqua Water System is running but water tests still show bacterial contamination, consider these possibilities: ensure the UV system is the last piece of treatment equipment, as equipment downstream might be a breeding ground for pathogens; ensure all distribution lines have been disinfected with chlorine; remove any pipe dead-ends and flush with chlorine.

    How to fix a leak from the UV chamber area of Viqua Water System?
    • L
      Lisa ParkerAug 16, 2025
      If you notice a leak from the UV chamber area of your Viqua Water System, the cause might be condensation of moist air on the cold chamber (control humidity or relocate the unit), a damaged, deteriorated, or incorrectly installed O-ring (inspect and replace if needed), or the lamp/sleeve assembly not properly installed (tighten the assembly hand-tight).

    How to fix a leak at the inlet or outlet of my Viqua Water System?
    • W
      Wendy LopezAug 21, 2025
      If there's a leak at the inlet or outlet of your Viqua Water System, the threaded pipe fittings may be leaking. Clean the threads, reseal with Teflon tape, and retighten them.
