Beschreibung
Zusammenfassung:	Improved valve assemblies (e.g., multi-position valve assemblies) are provided. More particularly, the present disclosure provides for high efficiency multi-position rotary backwash valve assemblies. In exemplary embodiments, the present disclosure provides for a four-position rotary high efficiency valve assembly for a swimming pool or spa filter. The present disclosure provides multi-position valve assemblies having infrequent maintenance and allowing for user-friendly service. The present disclosure provides for improved multi-position valve assemblies and related features, systems and methods of use. Improved, convenient and effective systems and methods for utilizing improved multi-position valve assemblies (e.g., high efficiency multi-position rotary backwash valve assemblies) are provided. The valve assembly can be utilized in fluid systems as a flow control assembly (e.g., as a backwash valve associated with a pool or spa filter).
