I choose the type based on how fast I need the valve to respond and how much backflow protection I want.

Size and Compatibility Are Important to Me

Before I buy, I always confirm the valve size. A PVC one way valve has to fit properly with my existing pipes or fittings. I also check whether it uses solvent weld, threaded, or push-fit connections. In my experience, the wrong connection type can cause installation trouble and leaks.

Pressure and Temperature Ratings I Check
