Ice Machine Backflow Preventer: Your Ultimate Guide
Ice Machine Backflow Preventer: Your Ultimate Guide
A backflow preventer is a device installed in the water line of an ice machine to prevent contaminated water from flowing back into the drinking water supply. This is important because ice machines can be a breeding ground for bacteria, which can cause illness if ingested.
Types of Backflow Preventers
There are two main types of backflow preventers:
1. Atmospheric vacuum breakers (AVBs): These devices use the weight of the atmosphere to prevent backflow. They are the most common type of backflow preventer used in ice machines.
2. Double check valves (DCVs): These devices use two check valves to prevent backflow. They are more expensive than AVBs, but they are also more reliable.
Importance of Backflow Preventers
Backflow preventers are an important part of any ice machine installation. They help to protect the public health by preventing contaminated water from flowing back into the drinking water supply.
According to the Centers for Disease Control and Prevention (CDC), backflow preventers can help to prevent the following waterborne diseases:
* Legionnaires disease
* Escherichia coli (E. coli)
* Cryptosporidium
* Giardia
Benefits of Backflow Preventers
In addition to protecting the public health, backflow preventers can also provide the following benefits:
* Protect your ice machine from damage
* Reduce the risk of water leaks
* Save money on water bills
How to Choose a Backflow Preventer
When choosing a backflow preventer for your ice machine, there are a few things to consider:
* The type of ice machine: There are different types of backflow preventers available for different types of ice machines.
* The size of the water line: The size of the backflow preventer will depend on the size of the water line.
* The location of the ice machine: The location of the ice machine will determine the type of backflow preventer that is required.
Installation and Maintenance
Backflow preventers should be installed by a qualified plumber. Once installed, backflow preventers should be tested annually to ensure that they are working properly.
Troubleshooting
If you are experiencing problems with your backflow preventer, there are a few things that you can do:
* Check the water pressure: The water pressure should be between 20 and 80 psi. If the water pressure is too low, the backflow preventer may not work properly.
* Clean the backflow preventer: The backflow preventer should be cleaned annually. To clean the backflow preventer, remove it from the water line and soak it in a solution of vinegar and water.
* Replace the backflow preventer: If the backflow preventer is damaged, it should be replaced.
Conclusion
Backflow preventers are an important part of any ice machine installation. They help to protect the public health, protect your ice machine from damage, reduce the risk of water leaks, and save money on water bills. If you are not sure whether or not your ice machine has a backflow preventer, contact a qualified plumber.
