OS&Y valves typically came FxF and hence the suction side fittings would all be flanged. Grooved OS&Y is becoming more popular... That being said, I have yet to see a pump with grooved inlets and outlets. Pros to all grooved are they are quicker to install. Pros to all flanged is they create a more stable/sturdy connection.

Please take care when clicking links or opening attachments. I've seen two schools of thought with regard to pump suction components. One way is flanged on the suction side and grooved on the discharge. The other is all grooved. I can; t see where NFPA-20 requires it either way. What's the popular choice and are there pro's & cons?
