Study Guide for NCCER Construction Technology

Describe the role of each major component in a typical home’s drainage and water distribution system.

• The drainage system removes wastewater and the water distribution system supplies clean water.

• The drainage system supplies clean water and the water distribution system removes wastewater.

• Both systems remove wastewater.

• Both systems supply clean water.

What steps would you follow to assemble a basic SWV system for a new residential building?

• Identify the components needed, plan the layout, install the system, test the system

• Purchase a pre-assembled SWV system, install it, and test it

• Consult with a professional, purchase components, and hire a contractor

• Research online, buy components, and assemble without a plan

Explain the process and materials required to install a water distribution system in a small commercial building.

• The process involves planning, selecting materials like pipes and valves, and installation.

• It requires only the selection of materials.

• The process is only about installation.

• It involves only planning.

Different plumbing fixtures and equipment like boilers and water heaters contribute to the functionality of a residential plumbing system by:

• providing heating and hot water supply

• enhancing the aesthetic appeal of the home

• reducing the need for regular maintenance

• increasing the water pressure in the system

What tools and techniques would you use to measure, cut, and join plastic and copper piping in a repair scenario?

• Use a hacksaw and soldering iron for copper, and a pipe cutter and adhesive for plastic.

• Use a pipe cutter and adhesive for both plastic and copper.

• Use a hacksaw and adhesive for both plastic and copper.

• Use a pipe cutter and soldering iron for plastic, and a hacksaw and adhesive for copper.

How do the drainage and water distribution systems in a building interact? Describe a scenario where a malfunction might occur.

• The drainage and water distribution systems in a building are completely independent and do not interact.

• The drainage system removes wastewater while the water distribution system supplies clean water, and a malfunction might occur if a pipe bursts, causing flooding.

• The drainage system supplies clean water and the water distribution system removes wastewater, and a malfunction might occur if a pipe bursts, causing flooding.

• The drainage and water distribution systems are the same, and a malfunction might occur if a pipe bursts, causing flooding.

An efficiently designed plumbing system can reduce water usage and impact overall energy costs in a building by:

• Reducing water waste and lowering heating costs

• Increasing water pressure and energy consumption

• Decreasing the need for water recycling systems

• Eliminating the use of renewable energy sources
