NOTE: These optional components are shown in a typical installation diagram. They should be used at the installer’s discretion as required for particular applications.
* When connected to a municipal system, if the plumbing does not have a backflow prevention device, a check valve is required on the incoming water supply line.
If installed on a cistern, the check valve should be passive or be eliminated.
