Red Seal Sprinkler Fitter Practice Exam

Identify a benefit of using CPVC pipes in sprinkler systems.

1. High weight and cost

2. Poor temperature resistance

3. Corrosion resistance

4. Complex installation process

The correct answer is: Corrosion resistance

Using CPVC (Chlorinated Polyvinyl Chloride) pipes in sprinkler systems offers significant benefits, particularly in terms of corrosion resistance. CPVC is resistant to a wide range of corrosive substances that can affect metal pipes, leading to longer-lasting systems with reduced maintenance needs. This characteristic is particularly advantageous in environments where chemicals may be present or in areas with high humidity that could promote corrosion in metal piping. The ability of CPVC to withstand the corrosive elements typically found in water resources helps to ensure the integrity of the sprinkler system over time, ultimately leading to more reliable fire protection. Additionally, the lightweight nature of CPVC makes it easier to handle and install, contributing to efficiency during the installation process. These properties are crucial for ensuring that the sprinkler system remains operable and effective over the long term.
