1-1/2 Inch PVC Check Valve

The Legend Valve 203-207 is a 1-1/2 inch S-611 PVC in-line check valve designed for plumbing installations. It uses a 1/2 lb stainless steel spring to prevent backflow in residential and commercial systems. The valve is supplied new and intended for standard piping applications.

Stainless Steel Spring Mechanism

The 1/2 lb stainless steel spring provides the closing force required to maintain a positive seal against reverse pressure. This component resists corrosion inside the PVC body, extending service life in water supply lines. No additional accessories or software are included with the valve.

Flow Capacity and Limits

The 1-1/2 inch connection size determines the flow volume the valve can accommodate in typical plumbing layouts. It handles standard pressure ranges for PVC piping but is not suited for high-pressure industrial systems or large-diameter mains. Installers should verify system pressure against the valve rating before use.

Questions about this item

Will the 1/2 lb stainless steel spring inside the S-611 check valve need periodic replacement?

The spring is built into the valve body and is not designed as a user-replaceable part; if it fatigues the entire valve is replaced.

What pressure or flow limit will the 1-1/2 inch PVC check valve reach first during continuous operation?

The valve opens at the 1/2 lb spring cracking pressure, so that low threshold is the first limit encountered under sustained flow.

How much noise or vibration does the S-611 PVC check valve produce when water runs through it all day?

The light 1/2 lb spring allows quiet opening, but water hammer can occur if flow stops suddenly; secure piping to minimise vibration.
