TYPES OF VENTS

Types of vents are numerous. Do you know what an island vent is? How much do you know about relief vents? Depending upon your level of knowledge in the plumbing trade, you might be aware of all types of vents, but not all read­ers are.

With this in mind, I will provide a number of vent drawings for readers to devour. So, let’s get on with the visual examples of various vent types.
