Question: 1 / 400

What type of connector is required to attach plastic DWV to cast iron DWV?

Screwed Connector

Hubless Connector

The required connector to attach plastic Drainage, Waste, and Vent (DWV) to cast iron DWV is a hubless connector. This type of connector is designed specifically for joining non-metal and metal pipes, such as plastic and cast iron. The hubless connector utilizes a rubber sleeve and a stainless-steel band to create a tight seal around the pipes, facilitating a secure and leak-free connection.

This method of connection is particularly advantageous in plumbing because it allows for flexibility and ease of installation, accommodating the different expansion and contraction rates of the materials involved. Furthermore, it complies with plumbing codes that dictate how different materials can be joined within a system. By employing a hubless connector, it ensures that the integrity of both the plastic and cast iron components is maintained without compromising the overall drainage system's functionality.
