Why is my RKIN Water Filtration System production limited?

  Selena DavisJul 29, 2025
  If your RKIN Water Filtration System has limited production, it might be due to several reasons. First, check the inner tube for any pinching and repair if necessary. Another potential cause is the water quality being outside the operating range; in this case, check the quality of the water to be filtered. If the filter elements have exceeded their useful life, replace them following the instructions on page 14. Taste and odor can also limit the production; flush the system by running 2 cycles and if the problem persists, replace the filters.
