5. Function (Operating Principle)
The float and vent assembly within the Watts 800M4 vacuum breaker plays a critical role in preventing backflow. When the water supply pressure drops or a vacuum condition occurs, the float drops, opening the vent. This allows air to enter the system, breaking the vacuum and preventing contaminated water from being siphoned back into the potable water supply. When pressure is restored, the float rises, sealing the vent and allowing normal water flow.
6. Bakım
Regular inspection and maintenance can extend the life of your vacuum breaker and ensure its continued effectiveness:
- Yıllık inceleme: Visually inspect the vacuum breaker annually for any signs of wear, cracks, or leaks.
- Bileşen Kontrolü: Periodically check the vent disc holder assembly and O-rings for signs of deterioration, such as hardening, cracking, or deformation. Replace components from this kit if wear is observed.
- Temizlik: If mineral deposits or debris accumulate, disassemble the unit (following installation steps 1-4) and clean the components with a soft brush and water. Avoid harsh chemicals.
- Kışa hazırlık (varsa): In freezing climates, ensure the vacuum breaker is properly drained or protected from freezing temperatures to prevent damage.
