La Marzocco Clip for PVC Tube GS3 Water Tank/Pump – Original Spare Part
Under the hood of the GS3, where water flows from the tank to the pump, a small plastic clip holds the PVC tube exactly where it belongs. A part you never see, as long as it does its job – and that's exactly the point.
Water makes up over 90% of espresso, and the journey there begins long before the brew group. If the tube slips at the connection, air can enter the circuit or the flow to the pump can become uneven. A new clip fixes the connection cleanly again – one of the smallest repairs with the biggest impact on a calm, steady water flow.

The Roastery Tip
