    Looks like a pressure release/safety valve, and yes you can replace it. But it looks like you might want to try cleaning it out first.

      Agreed, It looks fairly easy to disassemble and clean. I would attempt that before replacing. You may find a YouTube vid or two showing how. Pvc thread tape is your friend. Dirt in the valve will stop it from closings properly as pressure builds.
