That can bring a household to a screeching halt! There are two main causes of backflow in
plumbing – back pressure and back siphonage.
Back pressure is defined as water being forced to flow in the opposite
direction. Back siphonage might be more
complicated. It occurs when the pressure
in the water supply becomes smaller than the pressure in the plumbing system.
The most important thing is how is it prevented? Here are some tips –
1. Have a hose bib
backflow preventer
2. Have a vacuum
breaker that constantly monitors water pressure in the system
3. Something called a
barometric loop shaped like an inverted U
Now, what about fixing the problem if it occurs. That’s easy!
