Final answer:
Option inline water filters must be installed in any equipment that has a direct connection with potable water supply to ensure its safety for drinking and cooking.
Step-by-step explanation:
The correct answer is option inline water filters. Inline water filters must be installed in any equipment that has a direct connection with potable water supply, such as ice machines, coffee machines, and dishwashers.
These filters reduce the concentration of solutes in tap water, making it safe for drinking and cooking.
The correct answer is that any equipment with a direct connection to potable water supply must have a backflow prevention device installed.
This includes appliances like ice machines, coffee machines, and dishwashers. The primary role of this device is to prevent the reverse flow of contaminated water from these equipment back into the clean potable water supply, which could lead to health risks such as exposure to chemical pollutants or microorganisms.
Given that water is essential not only for basic survival but also for various daily activities, safeguarding the water supply through engineering controls like backflow prevention is crucial for public health and the functionality of modern water distribution systems.
