Why is there little or no flow from my Watson-Marlow Water Pump?
- NNicole MaloneAug 21, 2025
If your Watson-Marlow Water Pump is running but not producing adequate flow, consider the following: * Ensure fluid is being supplied to the pump. * Inspect the lines for kinks or blockages. * Verify that any valves in the line are open. * Confirm the tube and rotor are correctly placed in the pumphead. * Check the tube for splits or bursts. * Make sure you're using the correct wall-thickness tube. * Verify the direction of rotation. * Ensure the rotor isn't slipping on the drive shaft.
