Hose Bibb Vacuum Breakers

Vacuum Breakers stop the movement of water from the garden hose into the water supply. Water is only supposed to flow in one direction. Clean water flows to faucets. Dirty water from toilets or other drain lines go in one direction away from the clean water. Water flow creates pressure on the flow side. When the water pressure drops, it can create a siphon from your garden hose and send water, potentially dirty water, in your potable water supply. A breaker is installed at the end of your garden hose or hydrant to prevent liquids from being siphoned back into the clean water supply. We carry ASSE 1011 backflow preventers. These hose connection vacuum breakers have been tested at a recognized and listed third party testing lab that confirmed these valves meet the requirements of the American Society of Safety Engineers. 

Vacuum Breaker FAQ

Below you will find some of our most commonly asked questions pertaining to our vacuum breakers

What is a Vacuum Breaker?

A vacuum breaker is a backflow prevention device that stops water from your garden hose from flowing backward into your home’s clean water supply. It ensures that water only flows in one direction—outward. When water pressure drops, it can cause a siphon that pulls dirty water back into the potable water system. A vacuum breaker prevents this by sealing off reverse flow.

Why do I need a Vacuum Breaker?

Without a vacuum breaker, your garden hose can become a source of contamination. If the hose is submerged in dirty water—like a bucket, pond, or even a puddle—a sudden drop in water pressure can siphon that water back into your home's clean water lines. Vacuum breakers eliminate that risk, protecting your family and meeting plumbing codes in many areas.

Are your Vacuum Breakers certified?

Yes. We carry ASSE 1011 hose connection vacuum breakers. These backflow preventers have been third-party tested and certified to meet the requirements of the American Society of Safety Engineers. That means they are both effective and compliant with most plumbing codes.

Will your Vacuum Breakers fit my Hose Bibb?

Yes. Our vacuum breakers are made to fit standard 3/4" garden hose thread (GHT) connections, which are common on most hose bibbs and outdoor spigots. They can be easily installed without special tools—just screw them onto the outlet of your faucet or hose bibb.

Can the Vacuum Breaker be removed?

It depends on the model. Some vacuum breakers are permanent (tamper-resistant) to meet local plumbing codes, while others are removable for seasonal use. Check the product description to determine which style is right for your setup.
