Many parishes in Louisiana are starting to enforce the requirement to test your backflow assemblies. Thus, PIE Advisors’ backflow testing work has been increasing. PIE is nationally and state certified to test backflow assemblies. In addition, we work with many licensed plumbers that carry the water safety certification so on the chance your assembly fails, we can fix it! In addition our Business Partner – Backflow Prevention Services is a fully capable and certified cross connection control specialist and trainer for backflow assembly tester certification.
