What is the issue with the installation of the AVB in this scenario?
What is the issue with the installation of the AVB in this scenario?
- It is not compatible with atmospheric conditions
- It is not properly installed in the correct location
- It is under continuous pressure due to downstream shutoff valves (correct)
- It is not connected to separate irrigation zones
Why is the installation of the AVB considered improper in this case?
Why is the installation of the AVB considered improper in this case?
- It is not designed for use in irrigation systems
- It remains pressurized due to having downstream shutoff valves (correct)
- It does not provide atmospheric vacuum protection
- It lacks compatibility with other irrigation components
