Wet pipe sprinkler assessment checklist

01 What to verify first

1. The exact building area and scope under review
2. Whether the requirement is new work, alteration, repair or assessment
3. Which current approved plans and system records are available

02 Information to prepare

1. Floor plans, reflected ceiling information and room-use details
2. Available water-supply, pump, tank and riser records without estimating missing values
3. Photos and labels for existing valves, alarms, drains and affected pipework

03 Decision factors

1. Occupancy, storage and room-use information shown in the project documents
2. Existing-system condition and how the proposed work connects to it
3. Access, shutdown constraints, phasing and required project documentation

04 Common mistakes to avoid

1. Assuming visible pipe size proves system capacity
2. Sending plans without identifying the exact work area
3. Treating a product list as a complete system design
