Question

ABS and PVC-DWV installations shall be___________.

1) Installed by a licensed plumber
2) Installed by a certified electrician
3) Installed by a qualified HVAC technician
4) Installed by a trained carpenter

Answer 1

ABS and PVC-DWV installations should be installed by a licensed plumber, who has the expertise in plumbing systems required to handle these materials properly.

Step-by-step explanation:

The question pertains to the installation requirements for ABS (Acrylonitrile Butadiene Styrene) and PVC-DWV (Polyvinyl Chloride - Drain, Waste, and Vent) piping systems. Traditionally, these types of pipes are used in plumbing systems, and the installation guidelines specify that they should be installed by professionals who are trained and certified in handling these materials. This would typically mean that the installation should be done by a licensed plumber, as they are the professionals with the necessary expertise in plumbing systems rather than electricians, HVAC technicians, or carpenters.
