The return flow of water through a pipe is known as the reverse flow of water. To avoid backflow, you need to install special devices at each cross-connection point of apartments, buildings and other public & commercial places.
Cross-connection is the point in the plumbing system where the supply of clean water is connected to sources that cannot be drunk or water that is not suitable for drinking. If you are looking for gravesend plumber services then you can search through various online resources.

The type of backflow prevention needed will be in line with the level of danger present at the site. Drinking water or clean water flows under pressure in the city lanes to our homes. When backflow occurs, clean supplies begin to flow in the opposite direction and mix with dirty water.
Dirty water can be contaminated with dirt, chemicals, pesticides or other hazardous materials. Reverse flow can occur at the connection points between drinking water and non-drinking water in residential, commercial or industrial systems.
There are main reasons for reverse flow: Backsiphonage: This is a backflow of water due to negative pressure. Backsiphonage occurs when there is a sudden decrease in partial vacuum in the supply system. This draws water from contaminated sources into drinking supplies. Partial vacuum is created inside the pipe system which creates suction pressure of contaminated water into the drinking system.
