When preparing to use zone boosting, the size of the zone you choose must be ___ the size of the zone being boosted.

• A. Greater than
• B. Greater than or equal to
• C. Equal to
• D. Less than

Answer: (B)

When boosting a zone, plan for the boosting area to have at least the same capacity as the zone you’re boosting. The boost zone must be equal to or larger than the zone being boosted so it can supply enough flow or pressure to cover the entire area. If the boosting zone is smaller, some parts of the zone won’t receive adequate boost, defeating the purpose. Using a larger boost zone is acceptable if the system can sustain it, but the minimum requirement is that the boosting zone be greater than or equal in size to the zone being boosted.
