Fire Protection Systems Most water damage losses involving fire protection systems are the result of human activity, whether intentional or accidental. Other losses are the result of supply-main failure or freeze ups. Ensure that “Do Not Hang” signage is present in guest rooms to remind guests not to use pendent or sidewall sprinklers as clothing hangers. Provide portable hanging racks for guests with oversized garments. The failure of a bulk main is a severe water damage exposure. • Provide clearance around bulk mains where they pass through foundation walls or floors to help prevent damage from building settlement. External Water Exposures Water damage from external sources can occur if a building’s exterior is improperly graded and/or not resilient against entry. • Observe grading and other exterior conditions that can cause water to run-off toward a building. Properly protect potential points of entry. • Inspect roofs regularly and ensure: o All roof drains are unobstructed o Roof coverings and perimeter flashing are secured – Loose material/debris is removed o Openings (skylights, hatches, etc.) are properly sealed – Rooftop equipment is adequately secured o Perimeter downspouts are clear, terminate away from the building, and discharge at a safe location
• Weather seal exterior door and window openings.
• Provide backflow preventers on sewer lines where: o Sewer line is connected to a combined sanitary and runoff effluent line o Sewer line is cast iron and more than 30 years old – There is a history of sewer line backups
Sump pumps should be: o Rated for a minimum 50 gpm pumping capacity – Connected to a backup power source, if available o Equipped with monitored high water level alarms, especially for elevator pits
•
• In properties with Packaged Terminal Air Conditioner (PTAC) units: o Install units with internal drains
o For units with external drains, provide a minimum 2° slope to the outside o Ensure adequate caulking around the unit’s exterior sleeve and building wall
