State Certified backflow testing
Many Beverage Systems create and use Carbonated Water. When mixed with copper tubing and fittings it can create Carbonic Acid. If this is introduced into your water supply or the main water supply this can cause health issues. A properly installed, maintained, and tested Backflow Device prevents this.
cross connection :
a physical connection between drinkable water and a liquid or gas that could make the water unsafe to drink (wherever there is a cross connection, there is a potential threat to public health from the liquid or gas contaminants)
backflow :
water flowing opposite to its intended direction, either from a loss of pressure in the supply lines or an increase in pressure on the customer’s side (in either of these situations, if any affected customer’s pipes include a cross connection, contaminants could be drawn through the cross connection into that customer’s pipes—and, if the backflow continues, perhaps even into the water mains )
QUESTION:
Why do backflow preventers have to be tested periodically
ANSWER:
Mechanical backflow preventers have internal seals, springs, and moving parts that are subject to fouling, wear, or fatigue. Also, mechanical backflow preventers and air gaps can be bypassed. Therefore, all backflow preventers have to be tested periodically to ensure that they are functioning properly. Mechanical backflow preventers have to be tested with properly calibrated gauge equipment by a certified tester.
