A lubrication system is disclosed. The lubrication system may have a collection area for collecting lubricating media and a pumping system for transporting the lubricating media from a withdrawal location of the collection area to a distribution location of the collection area. The lubricating media may collect in the collection area to a static level when the pumping system is off and to a dynamic level when the pumping system is on. The lubrication system may also include a drain valve located between the static level and the dynamic level. The drain valve may operable to open to drain a portion of the lubricating media in response to the lubricating media reaching a predefined threshold temperature and level. The valve may comprise a thermally-activated material, and the material may substantially change phase or volume upon reaching a predetermined temperature.
