How to clean the Vitop S-Connector?

Unscrew the end fitting
Apply pressure from above to remove the valve
Clean the valve, spring, and the connector body, if necessary
Lubricate the valve with a food grease spray

Although many users simply flush a cleaning liquid periodically through the connector or let the entire connector sit in a sanitizing solution, it is also possible to disassemble the connector for complete cleaning of all components.

When putting the connector back together after cleaning, it is important to reseat the valve the right side up and to put back the spring.
