Question

Of those listed the acceptable fitting for connecting a horizontal drain line with another horizontal drain line is a?

1) Tee fitting
2) Elbow fitting
3) Coupling fitting
4) Union fitting

Answer 1

The correct answer is option 2) Elbow fitting. To connect a horizontal drain line with another horizontal drain line, the appropriate fitting is an elbow fitting, as it permits a smoother flow and mitigates the risk of clogging.

Step-by-step explanation:

When connecting a horizontal drain line with another horizontal drain line, a tee fitting is not acceptable as it does not allow for proper flow and can lead to blockages. The better choice would be an elbow fitting, which is designed to create a cleaner, 90-degree turn between two pipes, allowing for a smoother flow of waste water and a lower chance of clogging. A coupling fitting is used to connect two pipes of the same diameter, whereas a union fitting is designed to join two pipes end-to-end, facilitating future disconnection if necessary.

A tee fitting is used to connect two horizontal drain lines at a 90-degree angle. It has three openings, where one is used to connect to one drain line and the other two are used to connect to the other drain line. The tee fitting allows for a smooth flow of water from one drain line to another without any obstruction.
