In plumbing installations, what is the purpose of an isolation valve?

• A. To prevent backflow from fixtures
• B. To allow for repair without shutting off the main supply
• C. To regulate the pressure in the lines
• D. To connect multiple fixtures together

Answer: (B)

An isolation valve plays a crucial role in plumbing systems by allowing specific sections of the system to be shut off without affecting the overall water supply. This is particularly important for maintenance and repair work. When an isolation valve is installed, a plumber can easily isolate a fixture or a segment of piping, enabling them to perform necessary repairs or maintenance without the need to shut off the main water supply to the entire building. This functionality ensures minimal disruption to water service for other fixtures and simplifies the repair process. Understanding the purpose of an isolation valve clarifies its essential role in maintaining the overall efficiency and functionality of plumbing systems. This is particularly useful in residential or commercial environments where convenience and ongoing operation are priorities.
