PRESSURE BALANCED SIPHON BREAKER VALVES (and VACUUM BREAKER VALVES) are installed at the top of the pipe humps (comanding positions). They will break the vacuum and cut off the flow underneath in time when the systems are out of order or in need. This function surely safeguards the whole working units, keeping the flow from back running or the pump units running backwards which may easily cause the impellers to fly away.
