Q: How difficult is the installation process?

Detailed Features & Benefits
Enhanced Hygiene Solution: The ZERK-SM's touchless operation eliminates a primary touch point in restrooms, significantly reducing the transmission of germs and bacteria. This hands-free technology is particularly valuable in high-traffic commercial restrooms where hygiene is paramount, providing users with a more sanitary experience without requiring costly plumbing renovations.
True Mechanical Override System: Unlike electronic overrides found in competing products, the ZERK-SM features a genuine mechanical override button that ensures reliable operation even when batteries are completely depleted. This critical feature guarantees fixture functionality in all situations, preventing service disruptions and user frustration in busy commercial environments.
Intelligent Sensor Technology: The advanced infrared sensor is calibrated to detect user presence and provide reliable activation every time. The 3-second delay flush ensures the user has completed using the fixture before activation, optimizing water efficiency while maintaining proper fixture cleaning. The optional 24-hour auto-flush feature prevents odors and staining during periods of non-use.
NOTICE: All products come with a limited three-year warranty on materials and workmanship when properly installed and maintained according to instructions. Decorative finishes warranted for one year.
