What to do if my Watson-Marlow 630 U Water Pump runs but has little or no flow?
- SShane SmithAug 17, 2025
If your Watson-Marlow Water Pump is running but you're not getting the expected flow, here are a few things to check: * Make sure fluid is being supplied to the pump. * Inspect the lines for any kinks or blockages. * Ensure any valves in the line are open. * Verify the tube and rotor are correctly installed in the pumphead. * Check the tube for splits or bursts. * Confirm the correct wall-thickness tube is being used. * Check the direction of rotation. * Ensure the rotor isn't slipping on the drive shaft.
