The line on the spigot end of the push on joints needs to be pushed 'home' such that the line __________, when the joint is set completely, and the __________ end of the push on joint is the end that is beveled.

• A. is all the way to face of the bell, spigot
• B. is flush with the bell rim, bell
• C. protrudes beyond the bell, spigot
• D. seated halfway, bell

Answer: (A)

The line depth that signals full engagement is the main idea here. In push-on joints, a witness line on the spigot shows how far the spigot has been pushed into the bell. When the joint is fully set, that line should be at the face of the bell, indicating complete seating and a proper seal. The bevel is on the spigot end, which is the end that goes into the bell to ease insertion. So the correct statement is that the line is all the way to the face of the bell, and the beveled end is the spigot. If the line sits short, is flush with the rim, or protrudes, the joint isn’t fully seated and could leak.
