Product identity
The Legend Valve 203-205 is a 1 inch S-611 PVC in-line check valve equipped with a 1/2 lb stainless steel spring. It allows flow in one direction and prevents backflow in plumbing systems.
Who it suits and who it does not
It suits installers needing a compact PVC check valve with a light spring for low-pressure lines. It is not for buyers who require metal-body valves, higher cracking pressures or larger port sizes.
Build integration
The valve threads into 1 inch PVC piping and relies on solvent-weld or threaded connections supplied by the installer. Its plastic body frees the system from galvanic corrosion concerns when joined to dissimilar metals.

Questions about this item
What pipe size and fitting type must I already have for the 1" S-611 PVC check valve to connect?
You need a 1-inch PVC pipe run with solvent-weld sockets on both ends; the valve slips straight into the line and is cemented in place.
Will the 1/2 lb stainless-steel spring close reliably against the low back-pressure found in older gravity-fed systems?
Yes, the half-pound spring is light enough to seal under minimal reverse flow yet strong enough to prevent chatter in legacy low-head installations.
How can I verify the 203-205 valve is functioning correctly after cementing it into the line?
Pressurise the system and watch for zero downstream flow when the pump stops; a quiet, instant shut-off with no leakage past the disc confirms proper operation.
