Which materials are water-tight \ suitable for immersion in water?

  1. I was thinking of making a 3D printed part out of plastic to replace a broken part of a valve in a water tank.

    The water is not used for drinking but the part would need to be able to stand being immersed in cold water and not degrade and also it couldn't have water seeping through it or such.

    Are any of the materials here suitable for such use?
