Wastewater drain stopper system

A wastewater drain system, comprising:

• a body having a first, threaded end and a second end adapted for interconnection to wastewater drain pipes of a structure, the body having an opening for receipt of a ball rod;
• a flange interconnected to the first end of the body;
• a seal positioned about the body;
• a nut positioned about the body, the nut and the seal adapted to be abutted against an exterior of a fluid receptacle, wherein the flange is abutted against an interior of the fluid receptacle, and wherein the body is secured to the fluid receptacle by the flange and the nut;
• a stem having a proximal end and a distal end, the distal end operatively interconnected to an end of the ball rod, wherein the proximal end includes a stopper;
• an insert selectively interconnected to the flange;
• and
• wherein the stem can be moved with the ball rod from a first position of use to engage the stopper against a seat positioned in the body to prevent fluid flow through the wastewater drain system, and a second position of use that separates the stopper from the seat to allow fluid flow through the wastewater drain system.
