Straightline Backflow, Inc. is fully insured with A rated insurance 

A backflow prevention device/assembly is installed inside or/and outside of building or residential house and/or by a water meter to protect the public potable water from cross contamination.  In order to maintain that protection, backflow testing is performed to ensure that the backflow device is working probably.  If the backflow prevention device/assembly fails testing then it will need to be repaired and retested for proper operation.
