A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow. In water distribution systems , water is normally maintained at a significant pressure to enable water to flow from the tap, shower, or other fixture.

2023年5月31日 · Backflow preventers are key to maintaining safe, clean drinking water — especially in areas where non-potable water could mix with your potable water supply. This guide will discuss what a backflow preventer is, what it does, the three main kinds of backflow preventers, and why you might need one in your home.
2024年4月10日 · In this article, you can find information on what backflow is, types of backflow prevention devices, how these devices work, and how to install them in your home. What is backflow? Backflow is a plumbing term that refers to the pollution of a clean water line by contaminated water flowing in the reverse direction.
2021年9月30日 · High pressure goes to low pressure, always. The laws of physics will control how and where water will go. The water in piping systems can’t see the flow arrows on the outside of the piping — it simply searches for a lower pressure zone to move into. There are two distinct types of backflow.
In plumbing, the term backflow refers to water running in the wrong direction. As plumbing systems are designed to isolate and move water according to different stages of use, backflow can create contamination, property damage, and health risks.
2018年11月24日 · Backflow is defined as an undesirable reverse flow of water that returns contaminated water from a work site back to the potable water source. This can change the pH level of the pure water supply. If backflow occurs, it can lead to corrosion in industrial equipment.
The flow of piped medium in the direction opposite to normal flow is called backflow. It is caused by a difference in water pressures. Backflow is normally prevented by a non-return valve, and sometimes a gooseneck on the pipe system. In the pictured system, only the gooseneck will prevent backflow into the basement.
