Final answer:
All pipe, pipe fittings, traps, fixtures, materials, and devices used in plumbing systems should be carefully selected to ensure proper functioning and safety.
Step-by-step explanation:
In plumbing systems, all pipe, pipe fittings, traps, fixtures, materials, and devices should be carefully selected and installed to ensure proper functioning. It is important to use the appropriate materials that can handle the specific requirements of the plumbing system, such as water pipes for water supply lines and gas & fire pipelines for gas lines.
For example, water pipes may be made of materials like copper, PEX (cross-linked polyethylene), or CPVC (chlorinated polyvinyl chloride), while gas lines typically use materials like black iron or stainless steel. Pipe fittings, traps, and fixtures are also essential components that help connect and control the flow of water or gases in the system.
Using the correct materials and devices ensures the safety and efficiency of the plumbing system, preventing leaks, corrosion, or other issues that can cause damage or health hazards.
