Question

a form of individual venting where both waste pipe and vent pipe are installed together vertically is known as?
a. none
b. an individual wet vent
c. an individual back vent
d. an individual and continuous vent

Explanation:

An individual wet vent is a type of venting system where the waste pipe and vent pipe are installed together vertically. This allows for the proper venting of plumbing fixtures while also carrying waste. An individual back vent is a different type of venting that is not installed vertically with the waste pipe. An individual and continuous vent is also not the correct term for this specific installation. Since the question describes the waste and vent pipes installed together vertically, the correct answer is an individual wet vent.

Answer:

B. An Individual wet vent
