5-Step Guide on How to Remove Vacuum Breaker
For this demonstration, I’m using a T-550 faucet. But remember, you can apply the same process for any other faucet. However, when it comes to garden faucets, it is a bit different. So. I’ll explain it later in the article.
Things You’ll Need
- Adjustable pliers
Step 1 – Disconnect the Water Supply to the Faucet
First and foremost, locate and cut off the water supply for the faucet from which you plan to remove the vacuum breaker. It will be nearly impossible to carry out this process while water flows, so make sure it’s off.
Step 2 – Remove the Dust Cap
Then, locate the dust cap. As per my faucet, it is located at the top. Then, rotate the dust cap counterclockwise until you can get it out. You don’t need any tools for the step. Instead, use your hands.
Quick Tip: Dust cap protect the vacuum breaker from dust and debris. Most of the time, these dust caps are made from chrome brass or plastic.
Step 3 – Remove the Body
After removing the dust cap, you can locate the body of the vacuum breaker. For this, you’ll need adjustable pliers. On the surface of the vacuum breaker body, you can find 3 or 4 slots. Adjust the pliers to the size of the slots and turn them in a counterclockwise direction.
After two or three turns, you might be able to turn the vacuum breaker body using your hands.
Step 4 – Pull Out the Vacuum Breaker
A vacuum breaker usually comes with four parts; the body, stainless steel ball, spring, and a retainer tube.
So, pull out all the damaged parts from the hose bibb faucet.
The other three parts should come out easily after you remove the vacuum breaker body.
Step 5 – Vacuum Breaker Replacement
Finally, take a new vacuum breaker and place it on the faucet. Don’t forget to tighten the vacuum breaker body and the dust cap.
What If You are Using a Vacuum Breaker for a Garden Faucet?
As I mentioned earlier, garden faucets differ slightly from the others. According to the National Plumbing Code, you should have a vacuum breaker with every garden faucet. Otherwise, the water will travel backward and go into your house.
Quick Tip: Preventing backflow is the primary purpose of the vacuum breaker.
As you can see from the above image, the garden faucet has a vacuum breaker connected by a screw. So, follow these two steps to remove the vacuum breaker.
- Loosen the screw using a rachet
- Turn the vacuum breaker counterclockwise and pull it out
How Does the Vacuum Breaker Work?
The flowing water pressure opens the valve. So, when you turn off the water, there is no pressure, and the valve closes automatically. Because of that, the water won’t travel backward. That is why checking and replacing the vacuum breaker is a necessary process.
What is Backflow?
When the water flows backward, that process is recognized as a backflow. This common situation can occur in faucets if you don’t install a vacuum breaker.
For instance, the water will travel backward inside your house if your garden hose has no vacuum breaker. If this is drinking water, there won’t be any issues. But when the water is dirty, well, you can imagine.
Here are some troublesome situations where backflow can occur.
- An opened fire hydrant on your street
- Malfunctioning fire protection system
- Burst water main
