Legend Valve 203-106 T-611 PVC Check Valve 1-1/4

SKU CH-15W5-SS3SM

A 1-1/4 inch PVC in-line check valve with a stainless steel spring for flow control

  • PVC construction resists corrosion for long service life
  • 1-1/4 inch size fits standard plumbing connections
  • Stainless steel spring provides reliable backflow prevention
  • In-line design allows simple installation in existing pipe runs
  • California Proposition 65 warning indicates chemical safety compliance

Product Identity

The Legend Valve 203-106 is a T-611 PVC in-line check valve with a 1-1/4 inch connection. It uses a 1/2 lb stainless steel spring to prevent reverse flow in plumbing installations.

Who This Suits

This valve fits plumbers and maintenance teams needing a non-return device for PVC piping systems where chemical exposure warnings apply. It is not for installers who require metal-bodied valves, different spring pressures, or connections other than 1-1/4 inch solvent-weld ends.

Deciding Specification

The 1-1/4 inch PVC solvent-weld connection size determines whether this valve matches the existing pipework. Verify the pipe schedule and diameter before purchase to ensure a correct fit.

Questions about this item

How do I install the 1-1/4" T-611 PVC check valve and what is the common mistake?

Install the valve in-line with the flow arrow pointing downstream; the step often missed is confirming the 1/2 lb stainless steel spring orientation matches the intended flow direction before solvent-welding the joints.

What maintenance or replacement will the T-611 PVC check valve need over time?

Inspect the PVC body and stainless spring annually for scale build-up or spring fatigue; replace the entire valve if the flapper no longer seats cleanly or if cracking appears on the solvent-welded connections.

What is the first limit that appears on the T-611 PVC check valve under sustained flow?

The 1/2 lb stainless steel spring sets the cracking pressure; sustained flow above that pressure can cause premature spring fatigue and reduced sealing performance before the PVC body shows stress.
