This precision-engineered OEM component is absolutely critical for maintaining the one-way water flow necessary for stable pre-infusion and accurate brewing pressure. Featuring durable, food-grade materials and built to the exact specifications of the original manufacturer, this check valve ensures that water does not backflow into the system, which can cause pressure drops and inconsistent espresso extraction. If you are experiencing problems like a "leaking lever espresso group head" or "inconsistent pre-infusion pressure on my La Marzocco Leva," this bush check valve is the reliable solution.
The Bush Check Valve operates using a spring-loaded mechanism that precisely controls the flow direction within the lever group's hydraulic circuit.

Specifications include its exact dimensions and threading for perfect, leak-free compatibility with the lever group (consult your specific machine manual for proper fitment, often related to La Marzocco Leva models).
