Backflow is a major plumbing problem that can lead to water contamination.
Backflow is when water flow is reversed in pipe networks. This can cause clean and dirty water to mix and stop your plumbing working properly.
What causes backflow?
There are two things that can cause backflow:
- Back siphonage. This is when the supply end of a pipe loses pressure quickly. It creates a vacuum that can suck fluids back through the pipes and cause contamination.
- Back pressure. This is when the water pressure is reversed, usually from an outlet in the water mains.
What should I do if I’ve got backflow?
If you think you have backflow then the best thing to do is call in a professional plumber. Backflow can be a serious health risk and damage your plumbing system, so needs rectifying as soon as possible.
