It allows a full 200mL of water to build up in a spring-loaded reservoir and releases that full amount back through the brewing pipe over the 3-way solenoid and into your drip tray. That means less time spent cleaning, and 20x the volume of water used to clean per cycle.
Our brand new see-thru version allows you to watch the process in all its grime-removing glory, for a fraction of the price of the original.
Fits all standard 58mm portafilter machines that utilize a pump and backflush system for cleaning and maintenance. This includes E61 style group heads, most LaMarzocco (all except KB-90), and Decent compatible.
Our upgraded version has a dual-pressure valve safety group, which combines mechanical pressure relief with high-pressure valves to ensure user safety！
Upgrade the buckle handle similar to installing a water purifier, ensuring that it will not be scalded by hot water during use!
