WATTS Vacuum Breaker
Watts vacuum breakers are backflow preventers that attach to portable hoses, hose thread faucets or water supply fixtures and prevent the back siphonage / reverse flow of polluted or non-potable water into the potable water systems. These Watts 8 Series vacuum breakers protect users from health... hazards due to contaminated water in service sinks, swimming pools, urinals & wash racks.Read more

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.
Features
- Watts vacuum breakers feature brass construction with stainless steel working parts and have rubber diaphragm & disc for corrosion resistance and durability.
- They can be screwed directly onto a sill cock and require no plumbing changes.

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.
