Backflow Testing
The State of Connecticut Department of Public Health requires that your backflow prevention device be tested annually. This service requires special training and equipment and therefore will be billed separately from any other service. The cost of this test is $55.00. Grass Helper currently employs several state certified testers. For more information on cross connections, check out the following links.
