System Component and Hardware Series

When water needs to be removed from a sprinkler system, whether for testing, routine maintenance, or other reasons, it must be discharged efficiently, and sometimes very quickly. Following our previous videos on system components and hardware, we now arrive at drains , a critical part of sprinkler system design. This session will be especially valuable for designers, contractors, and inspectors seeking clarity on code compliance and practical applications. 🔹 Topics Covered: ✅ Purpose of drainage ✅ Drain design considerations (general requirements) ✅ Pipe slopes in different types of sprinkler systems (wet pipe system, dry pipe and preaction system) ✅ Different types of drains ✅ Main drain essentials: sizing, location and compliance (main drain, gauge placement for main drain, main drain test connection) ✅ Sectional drain essentials: sizing, location and compliance ✅ Auxiliary drains for wet pipe and preaction systems in areas not subject to freezing ✅ Auxiliary drains for dry pipe and preaction systems ✅ Automatic drip valve #fireprotection #sprinklersystems #NFPA13 #sprinklerdesign #Drains #codecompliance #NFPA25 #RahilKiaghadi
