Why is there low water flow from my Millipore DIRECT-Q 3 SYSTEM?

  David SteinAug 12, 2025
  If you experience low or no water flow when dispensing from your Millipore Water System, several factors could be the cause. First, ensure the water level in the tank is above 10%; if it's lower, allow the system to enter FILLING TANK mode. Next, verify that the Tank Outlet Valve is closed. An air-locked Millipak Filter can also cause this issue, so vent any trapped air. Lastly, a clogged Final Filter might be the culprit, requiring replacement.
