What fitting is used to connect the ejector pump outlet to a horizontal main?

Wye
Coupling
Cleanout
All of the above

The correct answer is: Wye

The correct choice is a wye fitting, which is specifically designed to connect pipes at a 45-degree angle, allowing for smoother flow and minimizing turbulence. This characteristic is particularly important when connecting an ejector pump outlet to a horizontal main because it helps to reduce the risk of clogging and allows fluids to flow more efficiently into the main line. Using other types of fittings would not provide the same benefits. A coupling, for example, is typically used to connect two straight sections of pipe in a linear fashion and does not accommodate the angle needed to match the flow direction from the ejector pump outlet to the horizontal main. Similarly, a cleanout is used for access and maintenance purposes but does not function as a fitting for connecting two pipes. While it’s crucial in the overall drainage system, it does not serve the connection purpose in this particular application. The wye fitting's design is thus essential in ensuring the proper functioning of the system, making it the most suitable choice for this application.
