    Hi,

    1. There are a few reasons why this may be happening.
    • Tube not fully inserted onto clear tube adapter
    • RO-style fittings are being used


    2. If by "red light" you mean the light on the left-side of the doser, that means the pump is currently running either due to a manual dose or scheduled dose.
