Product Identity

The Legend Valve 202-263 is a 3-inch S-641 backwater valve supplied with a sleeve. It is intended for drainage installations that require a backflow prevention device on a three-inch line.

Suitable Applications

This valve suits plumbers and contractors fitting a backwater device on a 3-inch pipe where a sleeve connection is specified. It does not suit installations that require a different pipe diameter, a different connection style, or a valve without an integrated sleeve.

Decisive Specification

The critical detail is the 3-inch S-641 designation with included sleeve, which determines whether the valve matches the piping system and connection method required for the job.

Questions about this item

What does the 3-inch size mean for my drainage pipe?

The 3-inch designation matches a standard 3-inch drainage pipe so the valve fits directly without adapters.

How does the S-641 backwater design work in the line?

The S-641 uses a flapper that opens for normal flow and closes automatically if sewage tries to reverse direction.

What does the included sleeve provide for installation?

The sleeve slides over the pipe ends to create a secure, sealed connection without extra couplings.
