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. Тэхнічнае абслугоўванне
Regular inspection and maintenance can extend the life of your vacuum breaker and ensure its continued effectiveness:
- Штогадовая праверка: Visually inspect the vacuum breaker annually for any signs of wear, cracks, or leaks.
- Праверка кампанента: 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.
- Уборка: 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.
- Уцяпленне (калі прыдатна): In freezing climates, ensure the vacuum breaker is properly drained or protected from freezing temperatures to prevent damage.
