Product Overview
The Pentair 263081 is a FullFloXF backwash valve built for D.E. filter installations that require a bottom-inlet valve arrangement. This SKU includes Pentair 2 in. unions and is used on compatible FNS Plus D.E. filter systems, making it a correct-fit replacement or service component where the original valve orientation and connection style must be maintained.
Its valve body is designed for routine filter and backwash operation in larger plumbing systems, with ports that support 2-1/2 in. direct plumbing and 3 in. slip-over connections when the proper fittings are used. The FullFloXF internal flow path helps reduce restriction during normal filtration, while the clearly marked operating positions support consistent day-to-day maintenance and backwash service.
