Hello everyone! I am new to this forum and am currently an apprentice plumber just starting out. I am confused on the dwv system . I understand a waste stack is for drainage but I am very confused on the venting system. What is the difference between a vent stack? and stack vent? I am currently working at an apartment building of five floors and the amount of dwv stacks is confusing any help appreciated thanks
