Backflow Testing

TANZ, Inc. is a NJ Licensed Back Flow Device Inspector Plumbing cross connections are actual or potential connections between a potable and non-potable or unapproved water supply and constitute a significant public health hazard and are controlled by the use of backflow prevention valves.

Therefore it is a state requirement to install and test backflow prevention devices on the public supply lines where they enter facilities, generally near the water meter on domestic lines and before the alarm check and siamese connection for fire lines. Testing must be completed by a certified tester with a valid backflow prevention device tester certificate. New Jersey regulations require backflow devices to be tested quarterly.
