Well its a question I get quizzed on time after time by my customers.
So here's the scenario, you've had a new place built whether it be domestic or commercial and the first annual test of your backflow valve has now fallen due since you took possession of the property. You contact Mayfair Plumbing and Gasfitting to book a plumber for the backflow test, the plumber arrives on site and whether it be a RPZ or a DCVA one of the check valves fails the test. The plumber approaches the customer and tells them of what is going on with there backflow preventor and immediately the question is asked "how is this possible as the backflow valve is only 12 months old?"
The answer to this is quite simple, all it takes is a small amount of debris to get into the backflow valve and mark the soft rubbers inside which seal against the seats to prevent backflow and no longer will the check valve inside the backflow prevention device seal properly. So it doesn't matter how young or old the backflow valve is it can fail a test at any time depending on the circumstances it is exposed to.
In this short video below from you tube it gives a detailed explanation of just what backflow is and the varying types of hazards which can be associated with backflow and the different valves we use to combat these hazards.
