Use the flow required by the manufacturer rather than assuming any visible water is sufficient. A partly blocked tap outlet or restricted supply can leave the disposer without adequate rinsing even though the tap is open.
What the observation tells you
Do not increase the food load to test the limit. Notice whether the flow has changed across other taps and whether a spray setting diverts water away from the opening. These observations help distinguish a supply issue from disposer performance.
A useful next step
Use a separate food-waste container until the required flow is available. If drainage is also slow, report both problems rather than treating extra tap pressure as the cure.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
