Sleeves must have a diameter how many inches greater than the pipe it serves?

The correct answer is: 2

Sleeves must have a diameter 2 inches greater than the pipe it serves because this additional space allows for easier installation and adjustment of the pipe within the sleeve, as well as accommodating any potential movements or variations in the pipe. Having a sleeve diameter that is 2 inches larger than the pipe diameter provides the necessary clearance without being excessive, ensuring proper functionality and ease of use.
