Vacuum Breaker

Vacuum Breakers

Vacuum Breakers provide effective protection against unwanted vacuum in the fuel oil piping. This is typicallyfound on a fuel system where the oil is pumped up to a much higher elevation. Once the pumping has stopped the oil will tend to want to return to the main tank. This can cause large vacuum in the supply line which could causeproblems. A vacuum breaker is typically installed in the line at the high point.
