A filter assembly for relieving hydrostatic pressure includes a housing with a flange and a shell. The flange includes an opening extending through the flange and the shell includes a base and a terminating end. The base of the shell is connected to the flange at the opening and extends away from the flange toward the terminating end. The filter assembly also includes a coupling mechanism with a drain pipe orifice to accept a drain pipe therein. The coupling mechanism is movably connected to the terminating end of the shell such that the coupling mechanism can move relative to the shell to change a position of the drain pipe orifice relative to the terminating end of the shell. The filter assembly also includes a filter cartridge removably positioned inside the shell and a face plate removably connected to the flange to secure the filter cartridge inside the shell.
