Essential Plumbing Tools Every Pro Should Know
What is the purpose of a plumbing air gap?
Correct Incorrect An air gap is a vital component in plumbing systems, designed to prevent contaminated water from siphoning back into the clean water supply. It physically separates the water supply outlet from the flood level of a fixture, ensuring that even if a vacuum occurs, the water cannot reverse flow. This simple yet effective method helps maintain sanitary conditions and public health.
