Product identity

The Legend Valve 203-237 S-614 is a PVC check valve designed for plumbing systems that require back-flow prevention. It suits installers and maintenance teams working on residential or light commercial pipework.

Upgrade path

This valve replaces a worn or missing check valve in 1-1/4" or 1-1/2" PVC lines. The jump is worth it when an existing valve no longer seals reliably or when a new installation demands a direct-fit PVC body.

Compatibility checks

Verify that the pipe schedule and solvent-cement method match PVC specifications before ordering. Confirm the line pressure and media are compatible with the valve materials and note the Proposition 65 warning for California installations.

Questions about this item

What pipe sizes does the 203-237 valve connect to?

The valve connects to 1-1/4 inch and 1-1/2 inch pipe sizes for solvent-weld installation on PVC piping systems.

How is the S-614 check valve installed and what is a common error?

Solvent-weld the valve into the pipeline with flow direction matching the arrow; a common error is installing it backwards which stops flow completely.

What maintenance or replacement will the PVC check valve need over time?

Inspect the internal flapper and seal periodically for debris or wear; replace the valve if the flapper fails to close or if cracking appears on the PVC body.
