This check valve comes with either 1/2 lb or 2 lb springs. When would I need a 2 lb spring?

Most systems will only require a 1/2 lb spring. The 2 lb spring is required for situations with greater head or backflow pressure. An example would be solar panels mounted on an 8' high roof.

Can the 1700C15 check valve be supplied with Viton seat material. EPDM doesn't have very good compatibility with chlorine and doesn't provide satisfactory service life.

Hi, Don. Unfortunately, the 1700C15 is not available with Vition seals.

installed this valve on the suction side of my new pump. Now my pump won't prime. I think the suction from the pump won't pull the spring valve open?

Hi. This check valve has a 1/2 lb spring, your pump should be sufficient to open the mechanism. I would check to see if the valve was installed correctly. The arrow pointing towards the pump inlet.
