What is a Vacuum Breaker?
Before diving into the steps for draining a vacuum breaker, it’s important to understand what it is and its purpose.
The Function of a Vacuum Breaker
A vacuum breaker is a safety device installed in plumbing systems. Its primary function is to prevent the creation of a vacuum that can draw contaminants back into the drinking water supply. This typically occurs when there is a sudden drop in pressure within the system. The vacuum breaker acts as a check valve, allowing air to enter the system and neutralize the vacuum effect.
Common Applications
Typically, vacuum breakers are found in various applications, including:
- Outdoor irrigation systems
- Hoses and hose bibs (outdoor faucets)
- Sprinkler systems
- Water fountains
Understanding where vacuum breakers are used can help homeowners identify where they need to focus their maintenance efforts.
Why is it Important to Drain a Vacuum Breaker?
Draining a vacuum breaker is necessary for several reasons:
Preventing Damage from Freezing
In colder climates, residual water inside the vacuum breaker can freeze, leading to cracks and extensive damage. This is particularly important during winter when temperatures drop significantly.
Avoiding Contamination
If water is allowed to sit in a vacuum breaker, it may become stagnant and potentially lead to contamination issues. Proper drainage helps maintain a clean and bacteria-free water supply.
How to Drain a Vacuum Breaker: A Step-by-Step Guide
Now that we understand the importance of proper maintenance, let’s get into the step-by-step process of draining a vacuum breaker. This process can apply to most common types of vacuum breakers found in residential setups.

The vacuum breaker is typically located near the top of your irrigation system, hoses, or outdoor faucets. It may look like a dome-shaped cap or a cylinder bolted to the plumbing.
Step 3: Open the Drain Valve
Many vacuum breakers come equipped with a drain valve.
Locating the Drain Valve
Look for a small valve or screw on the vacuum breaker itself. This valve is usually found at the bottom and may require a wrench to open.
Opening the Valve
- Place your bucket or container underneath the valve.
- Open the drain valve slowly and allow any residual water to flow into your container.
- If your vacuum breaker does not have a drain valve, you may need to remove the entire vacuum breaker for draining.
Step 4: Remove the Vacuum Breaker (If Necessary)
If there is no drain valve or if residual water still remains, you may need to take the vacuum breaker off the system for deeper cleaning.
- Use your wrench to unscrew the vacuum breaker gently.
- As you remove it, keep it level to avoid spilling any water.
- Once removed, turn it upside down to let any trapped water escape.
Step 5: Clean the Vacuum Breaker
While you have the vacuum breaker removed, this is an excellent opportunity to clean it.
- Use a towel or rag to wipe off any dirt or debris that may be present.
- Ensure that the air vents are clear of blockages to maintain proper function.
Step 6: Reinstall the Vacuum Breaker
After draining and cleaning the vacuum breaker, it’s time to put it back in place.
- Screw the vacuum breaker back onto the plumbing, ensuring a snug fit to prevent leaks.
- Tighten the connection using the wrench, but be careful not to overtighten.
Step 7: Restore the Water Supply
Once everything is securely in place, it’s time to turn the water supply back on.
- Go back to the main water supply valve and turn it on slowly.
- Check for any leaks around the vacuum breaker after restoring the water supply.
Step 8: Test the System
After the water supply is restored, it’s essential to test the system for functionality.
- Turn on any connected irrigation systems or faucets.
- Ensure that water flows properly and that there are no noticeable issues.
Additional Maintenance Tips for Vacuum Breakers
Proper maintenance extends beyond just draining the vacuum breaker. Here are some tips to ensure it operates efficiently throughout the year:
Regular Inspections
Make it a habit to check your vacuum breakers regularly, especially before winter. Look for any signs of wear, rust, or damage that might need addressing.
