CWorking Mechanism
- Thread a Watts vacuum breaker onto the hose bibb & hose. Then tighten the attached set screw till its head breaks off.
- These vacuum breakers allow passage of water in normal conditions and prevent the entry of air. However, when the water pressure at the unit's location decreases below a certain level, the volume breaker starts intaking air to break the suction effect caused by vacuum ( low pressure), thereby preventing backflow or back siphoning.
- They can be drained off in winters after use by removing the hose and lightly pulling down the knurled tip on the stem.

Frequently Asked Questions
How can users perform maintenance operations on these Watts vacuum breakers?
Does a vacuum breaker prevent freezing?
Yes, a properly drained out vacuum breaker can prevent freezing of the fixtures in winters to protect them from cracks.
What is the difference between a backflow preventer and a vacuum breaker?
Backflow preventers prevent the reverse flow of fluids irrespective of the type of fluids and their location. A vacuum breaker is a specialised backflow preventer that stops non potable water from back siphoning into the potable water supply.
What is Back siphonage?
Back siphonage or backflow in a system occurs when a negative pressure (vacuum or partial vacuum) zone is created in the supply piping. It results in siphoning effect from the contaminated water sources into the drinkable water supply lines.
