Applications

• Commercial buildings with visible exterior downspouts
• Institutional properties requiring long-term durability
• Industrial facilities exposed to heavy runoff
• Historic restorations where discrete but effective drainage is required

Installation Considerations

The Z199-DC should be securely fastened at the termination point of a downspout to ensure proper deflection of water. It must be positioned to direct flow away from walls, sidewalks, and foundations. During installation, confirm alignment for efficient drainage and allow for access if cleaning is necessary.

Case Study: Commercial Building Facade Protection

Challenge: A mid-sized office complex had recurring staining and deterioration along exterior walls due to uncontrolled stormwater discharge from downspouts. Maintenance teams frequently repainted walls and patched masonry.

Solution: Facility managers installed Zurn Z199-DC Downspout Covers across all exterior downspouts. The covers deflected water away from the façade while preventing debris buildup at the outlets.

Outcome: The building experienced immediate improvement. Wall staining stopped, repair costs decreased by 40%, and the facility projected long-term savings from reduced maintenance needs.

Conclusion

The Zurn Z199-DC Downspout Cover is a simple yet highly effective accessory for protecting building exteriors from stormwater damage. Its rugged construction, corrosion resistance, and ease of integration make it a smart choice for commercial, institutional, and industrial projects where durability and aesthetics both matter.
