Catch basin trap with collapsible outlet pipe connector and method of making a catch basin

A concrete catch basin, comprising:

• a sidewall having an opening therein;
• a catch basin trap attachable to the opening in the side wall of the catch basin, said catch basin trap including:
• a body being monolithically formed and having a front side wall for facing outwardly to outside of said catch basin, and a back side wall for facing inwardly to inside of said catch basin, said body defining a chamber located between said front side wall and said back side wall;
• an inlet opening in said back side wall of said body for receiving drainage water from said inside of said catch basin;
• an outlet opening in said front side wall of said body;
• a collapsible outlet pipe connector attached to said outlet opening, said collapsible outlet pipe connector being configured to be manipulated from a collapsed configuration to an extended configuration defining a discharge end adapted for coupling to an outlet pipe positioned outside said catch basin;
• a water flow path for said drainage water from said inlet opening to said collapsible outlet pipe connector, via said chamber, and said outlet opening;
• and
• an upstanding flange attaching said catch basin trap to said opening in said side wall of said catch basin, said upstanding flange embedded in said side wall of said catch basin;
• wherein said collapsed configuration stows said collapsible outlet pipe connector within said body, and said extended configuration permits watertight coupling of said discharge end of said collapsible outlet pipe connector to said outlet pipe.

A catch basin trap for attachment to an opening in a side wall of a catch basin, said catch basin trap comprising:

• a body having a front side wall for facing outwardly to outside of said catch basin, and a back side wall for facing inwardly to inside of said catch basin, said body being monolithically formed and defining a chamber located between said front side wall and said back side wall;
• an inlet opening in said back side wall of said body for receiving drainage water from said inside of said catch basin;
• an outlet opening in said front side wall of said body;
• a collapsible outlet pipe connector attached to said outlet opening, said collapsible outlet pipe connector being configured to be manipulated from a collapsed configuration to an extended configuration defining a discharge end adapted for coupling to an outlet pipe positioned outside said catch basin;
• a water flow path for said drainage water from said inlet opening to said collapsible outlet pipe connector, via said chamber, and said outlet opening;
• and
• an upstanding flange for attaching said catch basin trap to said opening in said side wall of said catch basin, said upstanding flange extending outwardly from said body continuously around a periphery of said body, between said front side wall and said back side wall, said upstanding flange being configured to have sufficient strength and resiliency to:
• support the body and maintain the position of the body during concrete casting of said catch basin in a mold such that the upstanding flange is embedded in the cast concrete and said body is held in said opening after said cast concrete catch basin has cured;
• and
• provide a substantially watertight seal between the body and the side wall of the catch basin when embedded in the side wall;
• wherein said collapsed configuration stows said collapsible outlet pipe connector within said body, and said extended configuration permits watertight coupling of said discharge end of said collapsible outlet pipe connector to said outlet pipe.
