For most of the substances, increasing the pressure when the system is in equilibrium between liquid and solid phases will increase the phase transition temperature. But since water fills a smaller volume when its liquid, rather than solid, it will go to lower melting point, allowing more solid to become liquid.
Eg- When skaters skate on ice, the increased pressure due to their weight causes ice to melt and allow them to move smoothly. When the pressure is removed, the water again freezes.
