A filter assembly for use in filtering stormwater includes a bottom including a boss that includes a rib extending laterally along an inner surface of the boss. The rib includes a locking portion that mates with a corresponding locking portion on a peripheral surface of a connection to an outlet conduit for securing the bottom to the connection thereby inhibiting rotation of the bottom relative to the outlet conduit. A center tube is secured to the bottom using a locking mechanism that inhibits relative movement between the bottom and the center tube. The center tube is in communication with an opening in the bottom and a hood is secured to the center tube. A filter medium is located between the hood and the center tube.
